+**Team Win Recovery Project (TWRP)**
+
+The goal of this branch is to rebase TWRP onto AOSP while maintaining as much of the original AOSP code as possible. This goal should allow us to apply updates to the AOSP code going forward with little to no extra work.  With this goal in mind, we will carefully consider any changes needed to the AOSP code before allowing them.  In most cases, instead of changing the AOSP code, we'll create our own functions instead.  The only changes that should be made to AOSP code should be those affecting startup of the recovery and some of the make files.
+
+If there are changes that need to be merged from AOSP, we will pull the change directly from AOSP instead of creating a new patch in order to prevent merge conflicts with AOSP.
+
+This branch is under final testing and will be used shortly for public builds, but has not officially been released.
+
+You can find a compiling guide [here](http://forum.xda-developers.com/showthread.php?t=1943625 "Guide").
+
+[More information about the project.](http://www.teamw.in/project/twrp2 "More Information")
+
+If you have code changes to submit those should be pushed to our gerrit instance.  A guide can be found [here](http://teamw.in/twrp2-gerrit "Gerrit Guide").

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+commit 2e20319843ea85d77c51a9ce9a9b278662426d98
+Author: Michael Casadevall <mcasadevall@ubuntu.com>
+Date:   Tue Jun 7 19:19:30 2011 +0200
+
+    Correcting miscalculation of sector number in some cases.
+    
+    mkdosfs will incorrectly calculate the number of sectors of a
+    given FAT partition if the number sectors are odd due to
+    count_blocks incorrectly handling the remainder of a division
+    operation. This miscalculation causes the OMAP4 bootloader to
+    fail to boot.
+    
+    This bug can be observed by comparing the total sector size in
+    fdisk expert more to fsck.msdos; this discrepancy only shows up
+    when the number of sectors are odd.
+    
+    See https://bugs.launchpad.net/ubuntu/+source/dosfstools/+bug/794043
+    for more information.

+
+    When compiling a 32-bit version of dosfstools on an x86_64 machine,
+    the resulting applications report strange errors on "large" (> 2 GiB)
+    partitions:
+    
+      Seek to -2118967808:Invalid argument
+    
+      Warning: Filesystem is FAT32 according to fat_length and fat32_length fields,
+      but has only 8613 clusters, less than the required minimum of 65525.
+      This may lead to problems on some systems.
+    
+    This appears to be due to compilation with a 32-bit off_t and lseek() library

+    
+    Use lseek64 for positioning, and change some suspect uses of off_t to loff_t.

+
+    On x86_64, dosfsck incorrectly claims that a free_cluster summary of
+    0xFFFFFFFF, defined by Microsoft to be "uninitialized," is wrong.

+    mkdosfs: correct alignment of the root directory.
+    
+    Correct the code to align the root directory; it was broken before
+    since bs.dir_entries had already been set at the point of alignment.
+    This patch removes the dual use of bs.dir_entries and root_dir_entries
+    to carry the same information: the information is carried in
+    root_dir_entires exclusively, and then bs.dir_entries is set inside
+    setup_tables() at a late point.
+    
+    The code to align the root directory is also wrapped in
+    if (align_structures); this avoids rounding the number of root
+    directory entries up to a whole sector when used with -a
+    (i.e. preserves the previous behavior.)

+
+    mkdosfs: by default align all structures to cluster boundaries
+    
+    Align all data structures (reserved sectors, FATs, root directory for
+    FAT12/16) to an even multiple of the cluster size. This means that if
+    the partition is aligned, so will all clusters be. This adds
+    significant performance for anything where the physical sector size is
+    larger than the logical sector size, e.g. flash media or large-sector
+    hard disks.

+Announcing the release of mkdosfs version 0.3b (Yggdrasil)
+
+It seems I didn't get the bug completely fixed in 0.3a.  Some
+borderline cases would still allocate too many sectors for the FAT.
+Again, nothing to worry about, just a nitpick -- this one would only
+in certain cases add one sector per FAT.
+
+Announcing the release of mkdosfs version 0.3a (Yggdrasil)
+
+Fixed a bug which would cause too many sectors to be reserved for the
+FAT (filesystem will still work fine, but have slightly less space
+available).
+
+Announcing the release of mkdosfs version 0.3 (Yggdrasil)
+
+This version correctly handles even very large filesystems, and
+properly supports the modern (3.3+) DOS bootsector format, including a
+message printed on boot attempts.

+			    --------------
+
+Announcing the release of mkdosfs version 0.2
+
+
+I've just uploaded mkdosfs to sunsite.unc.edu.  It works in a similar way
+to Remy Card's mke2fs, but creates an MS-DOS file system.
+
+The filename is mkdosfs-0.2.tar.gz.
+
+This second release should fix a small bug that could lead to FAT sizes that
+Linux's dosfs would accept but MS-DOS wouldn't.
+
+The archive contains a manual page, binary and source versions.

+version 2.11
+============
+
+ - all: don't use own llseek() anymore, glibc lseek() does everything we need
+ - dosfsck: lfn.c: avoid segfault
+ - dosfsck: check.c, lfn.c: check for orphaned LFN slots
+ - dosfsck: check.c alloc_rootdir_entry(): set owner of newly alloced clusters
+ - dosfsck: dosfsck.h: better use <byteswap.h> for byte swapping
+ - dosfsck: io.c: added code for real DOS
+ - mkdosfs: raised FAT12_THRESHOLD from 4078 to 4085, introduced MIN_CLUST_32
+ - mkdosfs: fix loop device size
+ - mkdosfs: by default, use FAT32 on devices >= 512MB
+ - mkdosfs: fix a memory leak (blank_sector)
+ - mkdosfs: fix parsing of number of blocks on command line, so that numbers
+   >2G can be used
+ - mkdosfs: add 'b' to getopt() string so this option can be used :)
+ - mkdosfs: fix parsing of -i arg (should be unsigned)
+ - mkdosfs: change default permissions of created images (-C) to 0666 & ~umask
+ - mkdosfs: relax geometry check: if HDIO_GETGEO fails, print a warning and
+   default to H=255,S=63
+ - dosfsck: new option -n (no-op): just check non-interactively, but
+   don't write anything to filesystem
+ - A few #include changes to support compilation with linux 2.6
+   headers (thanks to Jim Gifford <jim@jg555.com>)
+ - dosfsck: remove directory entries pointing to start cluster 0, if they're
+   not "." or ".." entries that should actually point to the root dir
+   (pointed out by Thomas Winkler <twinkler@sysgo.de>)
+ - mkdosfs: new option -h to set number of hidden sectors
+   (thanks to Godwin Stewart <gstewart@spamcop.net>)
+ - all: updated my mail address everywhere...
+
+version 2.10
+============
+
+ - dosfsck: various 64-bit fixes and removed some warnings by Michal
+   Cihar <mcihar@suse.cz>
+ - mkdosfs: better error message if called without parameters (also
+   suggested by Michal)
+
+version 2.9
+===========
+
+ - dosfsck: if EOF from stdin, exit with error code
+ - dosfsck: Fix potential for "Internal error: next_cluster on bad cluster".
+ - dosfsck: When clearing long file names, don't overwrite the dir
+   entries with all zeros, but put 0xe5 into the first byte.
+   Otherwise, some OSes stop reading the directory at that point...
+ - dosfsck: in statistics printed by -v, fix 32bit overflow in number
+   of data bytes.
+ - dosfsck: fix an potential overflow in "too many clusters" check
+ - dosfsck: fix 64bit problem in fat.c (Debian bug #152769)
+ - dosfsck: allow FAT size > 32MB.
+ - dosfsck: allow for only one FAT
+ - dosfsck: with -v, also check that last sector of the filesystem can
+   be read (in case a partition is smaller than the fs thinks)
+ - mkdosfs: add note in manpage that creating bootable filesystems is
+   not supported.
+ - mkdosfs: better error message with pointer to -I if target is a
+   full-disk device.
+
+version 2.8
+===========
+
+ - dosfsck: Fixed endless loop whenever a volume label was present.
+
+version 2.7
+===========
+
+ - dosfsck: Don't check volume label for bad characters, everything
+   seems to be allowed there... Also ignore duplicate names where one of
+   them is a volume label.
+
+version 2.6
+===========
+
+ - mkdosfs: Added correct heads definition for 2.88M floppies if not
+   created via loopback.
+ - dosfsck: If boot sector and its backup are different (FAT32), offer
+   to write the backup to sector 0. (tnx to Pavel Roskin for this)
+ - For 64 bit alpha, struct bootsector in dosfsck.h must be defined
+   with __attribute__((packed)).
+ - mkdosfs now actually accepts -R option. (tnx to David Kerrawn)
+ - Fixed typo in dosfsck boot.c (recognition of boot signature in FSINFO)
+ - Various compilation fixes for 2.4 kernel headers and for ia64.
+
+version 2.5
+===========
+
+ - The llseek() implementation for alpha didn't really work; fixed it.
+
+version 2.4
+===========
+
+ - Fix compiling problem on alpha (made a silly typo...)
+
+version 2.3
+===========
+
+ - mkdosfs: Fixed usage message (printed only "bad address").
+ - both: made man pages and usage statements more consistent.
+ - both: fix llseek function for alpha.
+ - dosfsck: fix reading of unaligned fields in boot sector for alpha.
+ - dosfsck: fixed renaming of files (extension wasn't really written).
+
+version 2.2
+===========
+
+ - Added dosfsck/COPYING, putting dosfsck officially under GPL (Werner
+   and I agree that it should be GPL).
+ - mkdosfs: Allow creation of a 16 bit FAT on filesystems that are too
+   small for it if the user explicitly selected FAT16 (but a warning
+   is printed). Formerly, you got the misleading error message "make
+   the fs a bit smaller".
+ - dosfsck: new option -y as synonym for -y; for compability with
+   other fs checkers, which also accept this option.
+ - dosfsck: Now prints messages similar to e2fsck: at start version
+   and feature list; at end number of files (and directories) and
+   number of used/total clusters. This makes the printouts of *fsck at
+   boot time nicer.
+ - dosfsck: -a (auto repair) now turns on -f (salvage files), too. -a
+   should act as non-destructive as possible, so lost clusters should
+   be assigned to files. Otherwise the data in them might be
+   overwritten later.
+ - dosfsck: Don't drop a directory with lots of bad entries in
+   auto-repair mode for the same reason as above.
+ - dosfsck: avoid deleting the whole FAT32 root dir if something is
+   wrong with it (bad start cluster or the like).
+ - general: also create symlinks {mkfs,fsck}.vfat.8 to the respective
+   real man pages.
+
+version 2.1
+===========
+
+ - Fix some forgotten loff_t's for filesystems > 4GB. (Thanks to
+   <ki@kretz.co.at>).
+ - Fix typo in mkdosfs manpage.
+ - Removed inclusion of <linux/loop.h> from mkdosfs.c; it's unnecessary and
+   caused problems in some environments.
+ - Fix condition when to expect . and .. entries in a directory. (Was
+   wrong for non-FAT32 if first entry in root dir was a directory also.)
+ - Also create mkfs.vfat and fsck.vfat symlinks, so that also
+   filesystems listed with type "vfat" in /etc/fstab can be
+   automatically checked.
+
+version 2.0
+===========
+
+ - merge of mkdosfs and dosfstools in one package
+ - new maintainer: Roman Hodek <Roman.Hodek@informatik.uni-erlangen.de>
+ - FAT32 support in both mkdosfs and dosfsck
+ - VFAT (long filename) support in dosfsck
+ - Support for Atari variant of MS-DOS filesystem in both tools
+ - Working support for big-endian systems in both tools
+ - Better support for loop devices in mkdosfs: usual floppy sizes are
+   detected and media byte etc. set accordingly; if loop fs has no
+   standard floppy size, use hd params
+   (mainly by Giuliano Procida <gpp10@cus.cam.ac.uk>)
+ - Removed lots of gcc warnings
+ - Fixed some minor calculation bugs in mkdosfs.
+

+dosfsck, version 1
+==================
+
+WARNING: This is ALPHA test software. Use at your own risk.
+
+dosfsck is the Linux equivalent of PC/MS-DOS' CHKDSK. It checks the
+consistency of PC/MS-DOS file systems and optionally tries to repair
+them. The tests dosfsck performs are described in the man page.
+
+dosfsck needs header files from dosfs.9 (or later) to compile.
+
+Before using dosfsck to repair a file system that contains data of any
+value, you should verify that dosfsck is able to correct all reported
+errors. (Except fatal errors and those reported as unfixable, of
+course.) In order to do this, run it with the -V option, e.g.
+
+   dosfsck -V /dev/sda1		(automatic check)
+or dosfsck -V -r /dev/sda1	(interactive check and repair)
+
+dosfsck will perform two passes: in the first pass, inconsistencies are
+detected and a list of changes to correct the problems is generated. In
+the second pass, those changes are applied whenever dosfsck reads data
+from disk. Hence no fixable errors should be reported in the second
+pass if the first pass was successful.
+
+Please notify the author if fixable errors are reported in the second
+pass.
+
+After verifying that dosfsck appears to be able to perform the desired
+operations, either confirm that you want the changes to be performed
+(if dosfsck was started with -r) or re-run dosfsck with the -a option
+(if it was started without -r).
+
+Please send bug reports, comments, flames, etc. to
+almesber@nessie.cs.id.ethz.ch  or  almesber@bernina.ethz.ch

+
+FAT32 and LFN support
+=====================
+
+I've finally implemented some of the new features of MS-DOS
+filesystems: FAT32 and long filenames.
+
+FAT32 is automatically detected and of course the different FAT
+structure is handled. (Internally many changes were needed, so 32 bit
+variables for all cluster numbers and 64 bit vars for offsets inside
+the filesystem.) New checks for FAT32 are most notably on the backup
+boot sector and the new info sector. Also the possibility that the
+root directory resides in a cluster chain (instead of in a static
+area) on FAT32 is handled.
+
+dosfscheck also knows about VFAT long filenames now. It parses those
+names and uses them in listings etc. when available. There are also
+some checks on the (cruel) structure of how LFNs are stored and some
+attempts to fix problems.

+
+Atari format support
+====================
+
+Both mkdosfs and dosfsck now can also handle the Atari variation of
+the MS-DOS filesystem format. The Atari format has some minor
+differences, some caused by the different machine architecture (m68k),
+some being "historic" (Atari didn't change some things that M$
+changed).
+
+Both tools automatically select Atari format if they run on an Atari.
+Additionally the -A switch toggles between Atari and MS-DOS format.
+I.e., on an Atari it selects plain DOS format, on any other machine it
+switches to Atari format.
+
+The differences are in detail:
+
+ - Atari TOS doesn't like cluster sizes != 2, so the usual solution
+   for bigger partitions was to increase the logical sector size. So
+   mkdosfs can handle sector sizes != 512 now, you can also manually
+   select it with the -S option. On filesystems larger than approx. 32
+   MB, the sector size is automatically increased (stead of the
+   cluster size) to make the filesystem fit. mkdosfs will always use 2
+   sectors per cluster (also with the floppy standard configurations),
+   except when directed otherwise on the command line.
+
+ - From the docs, all values between 0xfff8 and 0xffff in the FAT mark
+   an end-of-file. However, DOS usually uses 0xfff8 and Atari 0xffff.
+   This seems to be only an consmetic difference. At least TOS doesn't
+   complain about 0xffff EOF marks. Don't know what DOS thinks of
+   0xfff8 :-) Anyway, both tools use the EOF mark common to the
+   system (DOS/Atari).
+
+ - Something similar of the bad cluster marks: On Atari the FAT values
+   0xfff0 to 0xfff7 are used for this, under DOS only 0xfff7 (the
+   others can be normal cluster numbers, allowing 7 more clusters :-)
+   However, both systems usually mark with 0xfff7. Just dosfsck has to
+   interpret 0xfff0...0xfff7 differently.
+
+ - Some fields in the boot sector are interpreted differently. For
+   example, Atari has a disk serial number (used to aid disk change
+   detection) where DOS stores the system name; the 'hidden' field is
+   32 bit for DOS, but 16 bit for Atari, and there's no 'total_sect'
+   field; the 12/16 bit FAT decision is different: it's not based on
+   the number of clusters, but always FAT12 on floppies and FAT16 on
+   hard disks. mkdosfs nows about these differences and constructs the
+   boot sector accordingly.
+
+ - In dosfsck, the boot sector differences also have to known, to not
+   warn about things that are no error on Atari. In addition, most
+   Atari formatting tools fill the 'tracks' and 'heads' fields with 0
+   for hard disks, because they're meaningless on SCSI disks (Atari
+   has/had no IDE). Due to this, the check that they should be
+   non-zero is switched off.
+
+ - Under Atari TOS, some other characters are illegal in filenames:
+   '<', '>', '|', '"', and ':' are allowed, but all non-ASCII chars
+   (codes >= 128) are forbidden.

+mkdosfs - Make DOS file system utilty.
+
+
+I wrote this, partially to complement the dosfsck utility written by Werner
+Almesberger (who graciously gave me some pointers when I asked for some
+advice about writing this code), and also to avoid me having to boot DOS
+just to create data partitions (I use Linux to back up DOS :-) ).
+
+The code is really derived from Remy Card's mke2fs utility - I used this as a
+framework, although all of the file system specific stuff was removed and the
+DOS stuff inserted.  I believe originally mke2fs was based on Linus' mkfs
+code, hence the acknowledgements in the source code.
+
+Neither Remy nor Linus have had any involvement with mkdosfs, so if there are
+any bugs they're almost certainly "all my own work".
+
+The code has been available for ftp since 1st September 1993, and I have yet
+to receive any bug reports from users.  I don't know of any bugs, but if you
+do find a bug or have any constructive comments, please mail me!
+
+The only bug I found with version 0.1 was an obscure fault that could lead
+to an invalid (for MS-DOS, not Linux's dos fs) number of sectors used in the
+file allocation table(s).
+
+
+Dave Hudson
+dave@humbug.demon.co.uk
+
+
+FAT32 support
+=============
+
+mkdosfs now can also create filesystems in the new FAT32 format. To do
+this, give mkdosfs a "-F 32" option. FAT32 isn't selected
+automatically (yet), even if very large clusters are needed with
+FAT16. With FAT32 you have two additional options, -R to select the
+number of reserved sectors (usually 32), and -b to select the location
+of the backup boot sector (default 6). Of course such a backup is
+created, as well as the new info sector. On FAT32, the root directory
+is always created as a cluster chain. Sorry, there's no switch to
+generate an old static root dir.
+
+One bigger bug fix besides FAT32 was to reject filesystems that need a
+16 bit FAT to fit all possible clusters, but the bigger FAT needs some
+more sectors, so the total number of clusters drop below the border
+where MS-DOS expects a 12 bit FAT. So such filesystems would be FAT16,
+but interpreted as FAT32 by DOS. The fix is to reduce filesystem size
+a bit.

+
+.SH NAME
+\fBdosfsck\fR \- check and repair MS\-DOS filesystems
+
+.SH SYNOPSIS
+\fBdosfsck\fR|\fBfsck.msdos\fR|\fBfsck.vfat\fR [\-aAflnrtvVwy] [\-d \fIPATH\fR \-d\ \fI...\fR] [\-u\ \fIPATH\fR \-u \fI...\fR] \fIDEVICE\fR
+
+.SH DESCRIPTION
+\fBdosfsck\fR verifies the consistency of MS\-DOS filesystems and optionally tries to repair them.
+.PP
+The following filesystem problems can be corrected (in this order):
+.IP "*" 4
+FAT contains invalid cluster numbers. Cluster is changed to EOF.
+.IP "*" 4
+File's cluster chain contains a loop. The loop is broken.
+.IP "*" 4
+Bad clusters (read errors). The clusters are marked bad and they are removed from files owning them. This check is optional.
+.IP "*" 4
+Directories with a large number of bad entries (probably corrupt). The directory can be deleted.
+.IP "*" 4
+Files . and .. are non\-directories. They can be deleted or renamed.
+.IP "*" 4
+Directories . and .. in root directory. They are deleted.
+.IP "*" 4
+Bad filenames. They can be renamed.
+.IP "*" 4
+Duplicate directory entries. They can be deleted or renamed.
+.IP "*" 4
+Directories with non\-zero size field. Size is set to zero.
+.IP "*" 4
+Directory . does not point to parent directory. The start pointer is adjusted.
+.IP "*" 4
+Directory .. does not point to parent of parent directory. The start pointer is adjusted.
+.IP "*" 4
+Start cluster number of a file is invalid. The file is truncated.
+.IP "*" 4
+File contains bad or free clusters. The file is truncated.
+.IP "*" 4
+File's cluster chain is longer than indicated by the size fields. The file is truncated.
+.IP "*" 4
+Two or more files share the same cluster(s). All but one of the files are truncated. If the file being truncated is a directory file that has already been read, the filesystem check is restarted after truncation.
+.IP "*" 4
+File's cluster chain is shorter than indicated by the size fields. The file is truncated.
+.IP "*" 4
+Clusters are marked as used but are not owned by a file. They are marked as free.
+.PP
+Additionally, the following problems are detected, but not repaired:
+.IP "*" 4
+Invalid parameters in boot sector.
+.IP "*" 4
+Absence of . and .. entries in non\-root directories
+.PP
+When \fBdosfsck\fR checks a filesystem, it accumulates all changes in memory and performs them only after all checks are complete. This can be disabled with the \fB\-w\fR option.
+
+.SH OPTIONS
+.IP "\fB\-a\fR" 4
+Automatically repair the filesystem. No user intervention is necessary. Whenever there is more than one method to solve a problem, the least destructive approach is used.
+.IP "\fB\-A\fR" 4
+Use Atari variation of the MS\-DOS filesystem. This is default if \fBdosfsck\fR is run on an Atari, then this option turns off Atari format. There are some minor differences in Atari format: Some boot sector fields are interpreted slightly different, and the special FAT entries for end\-of\-file and bad cluster can be different. Under MS\-DOS 0xfff8 is used for EOF and Atari employs 0xffff by default, but both systems recognize all values from 0xfff8...0xffff as end\-of\-file. MS\-DOS uses only 0xfff7 for bad clusters, where on Atari values 0xfff0...0xfff7 are for this purpose (but the standard value is still 0xfff7).
+.IP "\fB\-d\fR" 4
+Delete the specified file. If more that one file with that name exists, the first one is deleted.
+.IP "\fB\-f\fR" 4
+Salvage unused cluster chains to files. By default, unused clusters are added to the free disk space except in auto mode (\fB\-a\fR).
+.IP "\fB\-l\fR" 4
+List path names of files being processed.
+.IP "\fB\-n\fR" 4
+No\-operation mode: non\-interactively check for errors, but don't write
+anything to the filesystem.
+.IP "\fB\-r\fR" 4
+Interactively repair the filesystem. The user is asked for advice whenever
+there is more than one approach to fix an inconsistency.
+.IP "\fB\-t\fR" 4
+Mark unreadable clusters as bad.
+.IP "\fB\-u\fR" 4
+Try to undelete the specified file. \fBdosfsck\fR tries to allocate a chain of contiguous unallocated clusters beginning with the start cluster of the undeleted file.
+.IP "\fB\-v\fR" 4
+Verbose mode. Generates slightly more output.
+.IP "\fB\-V\fR" 4
+Perform a verification pass. The filesystem check is repeated after the first run. The second pass should never report any fixable errors. It may take considerably longer than the first pass, because the first pass may have generated long list of modifications that have to be scanned for each disk read.
+.IP "\fB\-w\fR" 4
+Write changes to disk immediately.
+.IP "\fB\-y\fR" 4
+Same as \fB\-a\fR (automatically repair filesystem) for compatibility with other fsck tools.
+.PP
+\fBNote:\fR If \fB\-a\fR and \fB\-r\fR are absent, the filesystem is only checked, but not repaired.
+
+.SH "EXIT STATUS"
+.IP "0" 4
+No recoverable errors have been detected.
+.IP "1" 4
+Recoverable errors have been detected or \fBdosfsck\fR has discovered an internal inconsistency.
+.IP "2" 4
+Usage error. \fBdosfsck\fR did not access the filesystem.
+
+.SH FILES
+.IP "fsck0000.rec, fsck0001.rec, ..." 4
+When recovering from a corrupted filesystem, \fBdosfsck\fR dumps recovered data into files named 'fsckNNNN.rec' in the top level directory of the filesystem.
+
+.SH BUGS
+Does not create . and .. files where necessary. Does not remove entirely empty directories. Should give more diagnostic messages. Undeleting files should use a more sophisticated algorithm.

+.SH DESCRIPTION
+.B mkdosfs
+is used to create an MS-DOS file system under Linux on a device (usually
+a disk partition).
+.I device
+is the special file corresponding to the device (e.g /dev/hdXX).
+.I block-count
+is the number of blocks on the device.  If omitted,
+.B mkdosfs
+automatically determines the file system size.
+.SH OPTIONS
+.TP
+.B \-a
+Normally, for any filesystem except very small ones, \fBmkdosfs\fP
+will align all the data structures to cluster size, to make sure that
+as long as the partition is properly aligned, so will all the data
+structures in the filesystem.  This option disables alignment; this
+may provide a handful of additional clusters of storage at the expense
+of a significant performance degradation on RAIDs, flash media or
+large-sector hard disks.
+.TP
+.B \-A
+Use Atari variation of the MS-DOS file system. This is default if
+\fBmkdosfs\fP is run on an Atari, then this option turns off Atari
+format. There are some differences when using Atari format: If not
+directed otherwise by the user, \fBmkdosfs\fP will always use 2
+sectors per cluster, since GEMDOS doesn't like other values very much.
+It will also obey the maximum number of sectors GEMDOS can handle.
+Larger file systems are managed by raising the logical sector size.
+Under Atari format, an Atari-compatible serial number for the
+file system is generated, and a 12 bit FAT is used only for file systems
+that have one of the usual floppy sizes (720k, 1.2M, 1.44M, 2.88M), a
+16 bit FAT otherwise. This can be overridden with the \fB\-F\fP
+option. Some PC-specific boot sector fields aren't written, and a boot
+message (option \fB\-m\fP) is ignored.
+.TP
+.BI \-b " sector-of-backup "
+Selects the location of the backup boot sector for FAT32. Default
+depends on number of reserved sectors, but usually is sector 6. The
+backup must be within the range of reserved sectors.
+.TP
+.B \-c
+Check the device for bad blocks before creating the file system.
+.TP
+.B \-C
+Create the file given as \fIdevice\fP on the command line, and write
+the to-be-created file system to it. This can be used to create the
+new file system in a file instead of on a real device, and to avoid
+using \fBdd\fP in advance to create a file of appropriate size. With
+this option, the \fIblock-count\fP must be given, because otherwise
+the intended size of the file system wouldn't be known. The file
+created is a sparse file, which actually only contains the meta-data
+areas (boot sector, FATs, and root directory). The data portions won't
+be stored on the disk, but the file nevertheless will have the
+correct size. The resulting file can be copied later to a floppy disk
+or other device, or mounted through a loop device.
+.TP
+.BI \-f " number-of-FATs"
+Specify the number of file allocation tables in the file system.  The
+default is 2.  Currently the Linux MS-DOS file system does not support
+more than 2 FATs.
+.TP
+.BI \-F " FAT-size"
+Specifies the type of file allocation tables used (12, 16 or 32 bit).
+If nothing is specified, \fBmkdosfs\fR will automatically select
+between 12, 16 and 32 bit, whatever fits better for the file system size.
+.TP
+.BI \-h " number-of-hidden-sectors "
+Select the number of hidden sectors in the volume. Apparently some
+digital cameras get indigestion if you feed them a CF card without
+such hidden sectors, this option allows you to satisfy them. Assumes
+\'0\' if no value is given on the command line.
+.TP
+.I \-i " volume-id"
+Sets the volume ID of the newly created file system;
+.I volume-id
+is a 32-bit hexadecimal number (for example, 2e24ec82).  The default
+is a number which depends on the file system creation time.
+.TP
+.B \-I
+It is typical for fixed disk devices to be partitioned so, by default, you are
+not permitted to create a filesystem across the entire device.
+.B mkdosfs
+will complain and tell you that it refuses to work.  This is different
+when using MO disks.  One doesn't always need partitions on MO disks.
+The file system can go directly to the whole disk.  Under other OSes
+this is known as the 'superfloppy' format.
+
+This switch will force
+.B mkdosfs
+to work properly.
+.TP
+.BI \-l " filename"
+Read the bad blocks list from
+.IR filename .
+.TP
+.BI \-m " message-file"
+Sets the message the user receives on attempts to boot this file system
+without having properly installed an operating system.  The message
+file must not exceed 418 bytes once line feeds have been converted to
+carriage return-line feed combinations, and tabs have been expanded.
+If the filename is a hyphen (-), the text is taken from standard input.
+.TP
+.BI \-n " volume-name"
+Sets the volume name (label) of the file system.  The volume name can
+be up to 11 characters long.  The default is no label.
+.TP
+.BI \-r " root-dir-entries"
+Select the number of entries available in the root directory.  The
+default is 112 or 224 for floppies and 512 for hard disks.
+.TP
+.BI \-R " number-of-reserved-sectors "
+Select the number of reserved sectors. With FAT32 format at least 2
+reserved sectors are needed, the default is 32. Otherwise the default
+is 1 (only the boot sector).
+.TP
+.BI \-s " sectors-per-cluster"
+Specify the number of disk sectors per cluster.  Must be a power of 2,
+i.e. 1, 2, 4, 8, ... 128.

+.BI \-S " logical-sector-size"
+Specify the number of bytes per logical sector.  Must be a power of 2
+and greater than or equal to 512, i.e. 512, 1024, 2048, 4096, 8192,
+16384, or 32768.
+.TP
+.B \-v
+Verbose execution.
+.SH BUGS
+.B mkdosfs
+can not create boot-able file systems. This isn't as easy as you might
+think at first glance for various reasons and has been discussed a lot
+already.
+.B mkdosfs
+simply will not support it ;)

+/* Description: Utility to allow an MS-DOS filesystem to be created
+   under Linux.  A lot of the basic structure of this program has been
+   borrowed from Remy Card's "mke2fs" code.
+
+   As far as possible the aim here is to make the "mkdosfs" command
+   look almost identical to the other Linux filesystem make utilties,
+   eg bad blocks are still specified as blocks, not sectors, but when
+   it comes down to it, DOS is tied to the idea of a sector (512 bytes
+   as a rule), and not the block.  For example the boot block does not
+   occupy a full cluster.
+
+   Fixes/additions May 1998 by Roman Hodek
+   <Roman.Hodek@informatik.uni-erlangen.de>:
+   - Atari format support
+   - New options -A, -S, -C
+   - Support for filesystems > 2GB
+   - FAT32 support */

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+1.0.0 (2013-01-19)
+
+* Fixed crash when renaming a file within a single directory and a new name
+differs only in case.
+* Fixed clusters allocation: a cluster beyond valid clusters range could be
+allocated.
+* Fixed crash when a volume is unmounted while some files are open.
+* SConscript now respects AR and RANLIB environment variables.
+* Improved error handling.
+
+Linux:
+
+* Enabled big_writes. This improves write speed (larger block size means less
+switches between kernel- and user-space).
+* Do BLKROGET ioctl to make sure the device is not read-only: after
+"blockdev --setro" kernel still allows to open the device in read-write mode
+but fails writes.
+
+OS X:
+
+* Fixed OS X 10.8 support.
+* Switched to 64-bit inode numbers (now Mac OS X 10.5 or later is required).
+* Switched from unmaintained MacFUSE to OSXFUSE (http://osxfuse.github.com).
+* Fixed device size detection. Now mkfs works.
+* Workarounded some utilities failures due to missing chmod() support.
+* Disabled (senseless) permission checks made by FUSE.
+
+0.9.8 (2012-08-09)
+
+* The mkfs utility can now create huge file systems (up to several exabytes).
+* Fixed handling of characters beyond Basic Multilingual Plane.
+* Echo messages to syslog only if stderr is not connected to a terminal.
+
+0.9.7 (2012-03-08)
+
+* Out-of-the-box FreeBSD support (via ublio library).
+* Fixed "missing EOD entry" error (could happen while reading directory that
+consists of several clusters).
+* Fixed interpretation of minutes field in files timestamps (minutes could be
+displayed incorrectly).
+* Fixed mtime seconds field initialization for newly created file (mtime could
+be 1 sec less than creation time).
+* SConscript now respects CC, CCFLAGS and LDFLAGS environment variables.

+* Fixed write performance regression introduced in 0.9.4.
+* Mount in read-only mode if the device is write-protected.
+* Set ctime to mtime to ensure we don't break programs that rely on ctime
+(e.g. rsync considered that all files are outdated) [Eldad Zack].
+* Indicate that FS in not clean when it was not cleanly unmounted.
+* Utilities are now compatible with GNU/Hurd.
+* Fixed several memory leaks that could occur on error handling paths.
+* Improved handling of corrupted file systems.
+
+0.9.5 (2011-05-15)
+
+* Fixed erasing of the root directory cluster when creating a new FS with
+mkexfatfs. This bug could cause mkexfatfs to produce invalid FS.
+* Utilities are not linked with libfuse anymore.
+* Ensure that the path being opened is either a device or a regular file.
+
+0.9.4 (2011-03-05)
+
+* Introduced exfat-utils: dumpexfat, exfatfsck, mkexfatfs, exfatlabel.
+* Fixed "Invalid argument" error while mounting a volume from a disk with sector size greater than 512 bytes.
+* Wait for all data to be flushed to disk on unmount.
+* Kernel cache is no longer flushed on open. This can slightly improve read performance by avoiding extra read requests from kernel to user-space.
+* Allow to unmount volumes as user (fusermount -u) if they were mounted from the very same user [Tino Lange].
+* Errors and warnings are now duplicated to syslog.
+
+0.9.3 (2010-09-25)
+
+* Directories now can shrink.
+* Improved timestamps resolution from 2 sec to 1 sec.
+* Fixed timestamps displaying under Mac OS X when compiled for i386 or ppc.
+* Fixed FS size displaying for non-GNU systems.
+
+0.9.2 (2010-07-24)
+
+* Fixed a bug which could cause the whole directory to become unreadable after renaming a file in it.
+* Support for Solaris and various *BSD [Albert Lee].
+* Improved error handling on corrupted volumes.
+* Improved allowed file name characters filter.
+* Added man page.
+
+0.9.1 (2010-06-12)
+
+* Implemented automounting (util-linux-ng 2.18 or later is required).
+* Fixed mounting when cluster bitmap is larger than expected.
+* Fixed crash on statfs() when root directory contains error.
+* Fixed bugs specific to big-endian machines.
+* Other bugfixes.
+
+0.9.0 (2010-03-21)
+
+* Initial release.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+.SH NAME
+.B mkexfatfs
+\- create an exFAT file system
+.SH SYNOPSIS
+.B mkexfatfs
+[
+.B \-i
+.I volume-id
+]
+[
+.B \-n
+.I volume-name
+]
+[
+.B \-p

+]
+[
+.B \-V
+]
+.I device
+
+.SH DESCRIPTION
+.B mkexfatfs
+creates an exFAT file system on a block device.
+.I device
+is a special file corresponding to the device.
+
+.SH OPTIONS
+Command line options available:
+.TP
+.BI \-i " volume-id"
+A 32-bit hexadecimal number. By default a value based on current time is set.
+.TP
+.BI \-n " volume-name"
+Volume name (label), up to 15 characters. By default no label is set.
+.TP
+.BI \-p " partition-first-sector"
+First sector of the partition starting from the beginning of the whole disk.
+exFAT super block has a field for this value but in fact it's optional and
+does not affect anything. Default is 0.
+.TP
+.BI \-s " sectors-per-cluster"
+Number of physical sectors per cluster (cluster is an allocation unit in
+exFAT). Must be a power of 2, i.e. 1, 2, 4, 8, etc. Cluster size can not
+exceed 32 MB. Default cluster sizes are:
+4 KB if volume size is less than 256 MB,
+32 KB if volume size is from 256 MB to 32 GB,
+128 KB if volume size is 32 GB or larger.
+.TP
+.BI \-V
+Print version and copyright.
+
+.SH EXIT CODES
+Zero is returned on successful creation. Any other code means an error.

+ *   Henceforth the source version will match the shared-library major
+ *   and minor numbers; the shared-library major version number will be
+ *   used for changes in backward compatibility, as it is intended.  The
+ *   PNG_LIBPNG_VER macro, which is not used within libpng but is available
+ *   for applications, is an unsigned integer of the form xyyzz corresponding
+ *   to the source version x.y.z (leading zeros in y and z).  Beta versions
+ *   were given the previous public release number plus a letter, until
+ *   version 1.0.6j; from then on they were given the upcoming public
+ *   release number plus "betaNN" or "rcNN".
+ *
+ *   Binary incompatibility exists only when applications make direct access
+ *   to the info_ptr or png_ptr members through png.h, and the compiled
+ *   application is loaded with a different version of the library.
+ *
+ *   DLLNUM will change each time there are forward or backward changes
+ *   in binary compatibility (e.g., when a new feature is added).
+ *
+ * See libpng-manual.txt or libpng.3 for more information.  The PNG
+ * specification is available as a W3C Recommendation and as an ISO
+ * Specification, <http://www.w3.org/TR/2003/REC-PNG-20031110/

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ *    March 28, 2013
+ *
+ *    Since the PNG Development group is an ad-hoc body, we can't make
+ *    an official declaration.
+ *
+ *    This is your unofficial assurance that libpng from version 0.71 and
+ *    upward through 1.6.1 are Y2K compliant.  It is my belief that
+ *    earlier versions were also Y2K compliant.
+ *
+ *    Libpng only has two year fields.  One is a 2-byte unsigned integer
+ *    that will hold years up to 65535.  The other, which is deprecated,
+ *    holds the date in text format, and will hold years up to 9999.
+ *
+ *    The integer is
+ *        "png_uint_16 year" in png_time_struct.
+ *
+ *    The string is
+ *        "char time_buffer[29]" in png_struct.  This is no longer used
+ *    in libpng-1.6.x and will be removed from libpng-1.7.0.
+ *
+ *    There are seven time-related functions:
+ *        png.c: png_convert_to_rfc_1123_buffer() in png.c
+ *          (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
+ *          png_convert_to_rfc_1152() in error prior to libpng-0.98)
+ *        png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ *        png_convert_from_time_t() in pngwrite.c
+ *        png_get_tIME() in pngget.c
+ *        png_handle_tIME() in pngrutil.c, called in pngread.c
+ *        png_set_tIME() in pngset.c
+ *        png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ *    All handle dates properly in a Y2K environment.  The
+ *    png_convert_from_time_t() function calls gmtime() to convert from system
+ *    clock time, which returns (year - 1900), which we properly convert to
+ *    the full 4-digit year.  There is a possibility that libpng applications
+ *    are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
+ *    function, or that they are incorrectly passing only a 2-digit year
+ *    instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ *    but this is not under our control.  The libpng documentation has always
+ *    stated that it works with 4-digit years, and the APIs have been
+ *    documented as such.
+ *
+ *    The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
+ *    integer to hold the year, and can hold years as large as 65535.
+ *
+ *    zlib, upon which libpng depends, is also Y2K compliant.  It contains
+ *    no date-related code.

+/* How the alpha channel is interpreted - this affects how the color channels of

+ *
+ * This has no effect on the way pixels are written into a PNG output
+ * datastream. The color samples in a PNG datastream are never premultiplied
+ * with the alpha samples.
+ *
+ * The default is to return data according to the PNG specification: the alpha
+ * channel is a linear measure of the contribution of the pixel to the
+ * corresponding composited pixel.  The gamma encoded color channels must be
+ * scaled according to the contribution and to do this it is necessary to undo
+ * the encoding, scale the color values, perform the composition and reencode
+ * the values.  This is the 'PNG' mode.
+ *
+ * The alternative is to 'associate' the alpha with the color information by
+ * storing color channel values that have been scaled by the alpha.  The
+ * advantage is that the color channels can be resampled (the image can be
+ * scaled) in this form.  The disadvantage is that normal practice is to store
+ * linear, not (gamma) encoded, values and this requires 16-bit channels for
+ * still images rather than the 8-bit channels that are just about sufficient if
+ * gamma encoding is used.  In addition all non-transparent pixel values,
+ * including completely opaque ones, must be gamma encoded to produce the final
+ * image.  This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
+ * latter being the two common names for associated alpha color channels.)
+ *
+ * Since it is not necessary to perform arithmetic on opaque color values so
+ * long as they are not to be resampled and are in the final color space it is
+ * possible to optimize the handling of alpha by storing the opaque pixels in
+ * the PNG format (adjusted for the output color space) while storing partially
+ * opaque pixels in the standard, linear, format.  The accuracy required for
+ * standard alpha composition is relatively low, because the pixels are
+ * isolated, therefore typically the accuracy loss in storing 8-bit linear
+ * values is acceptable.  (This is not true if the alpha channel is used to
+ * simulate transparency over large areas - use 16 bits or the PNG mode in
+ * this case!)  This is the 'OPTIMIZED' mode.  For this mode a pixel is
+ * treated as opaque only if the alpha value is equal to the maximum value.
+ *
+ * The final choice is to gamma encode the alpha channel as well.  This is
+ * broken because, in practice, no implementation that uses this choice
+ * correctly undoes the encoding before handling alpha composition.  Use this
+ * choice only if other serious errors in the software or hardware you use
+ * mandate it; the typical serious error is for dark halos to appear around
+ * opaque areas of the composited PNG image because of arithmetic overflow.
+ *
+ * The API function png_set_alpha_mode specifies which of these choices to use
+ * with an enumerated 'mode' value and the gamma of the required output:

+ * computer display system; for example 2.2 for an sRGB conformant system.  The
+ * values are scaled by 100000 in the _fixed version of the API (so 220000 for
+ * sRGB.)
+ *
+ * The inverse of the value is always used to provide a default for the PNG file
+ * encoding if it has no gAMA chunk and if png_set_gamma() has not been called
+ * to override the PNG gamma information.
+ *
+ * When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
+ * opaque pixels however pixels with lower alpha values are not encoded,
+ * regardless of the output gamma setting.
+ *
+ * When the standard Porter Duff handling is requested with mode 1 the output
+ * encoding is set to be linear and the output_gamma value is only relevant
+ * as a default for input data that has no gamma information.  The linear output
+ * encoding will be overridden if png_set_gamma() is called - the results may be
+ * highly unexpected!
+ *
+ * The following numbers are derived from the sRGB standard and the research
+ * behind it.  sRGB is defined to be approximated by a PNG gAMA chunk value of
+ * 0.45455 (1/2.2) for PNG.  The value implicitly includes any viewing
+ * correction required to take account of any differences in the color
+ * environment of the original scene and the intended display environment; the
+ * value expresses how to *decode* the image for display, not how the original
+ * data was *encoded*.
+ *
+ * sRGB provides a peg for the PNG standard by defining a viewing environment.
+ * sRGB itself, and earlier TV standards, actually use a more complex transform
+ * (a linear portion then a gamma 2.4 power law) than PNG can express.  (PNG is
+ * limited to simple power laws.)  By saying that an image for direct display on
+ * an sRGB conformant system should be stored with a gAMA chunk value of 45455
+ * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+ * makes it possible to derive values for other display systems and
+ * environments.
+ *
+ * The Mac value is deduced from the sRGB based on an assumption that the actual
+ * extra viewing correction used in early Mac display systems was implemented as
+ * a power 1.45 lookup table.
+ *
+ * Any system where a programmable lookup table is used or where the behavior of
+ * the final display device characteristics can be changed requires system
+ * specific code to obtain the current characteristic.  However this can be
+ * difficult and most PNG gamma correction only requires an approximate value.
+ *
+ * By default, if png_set_alpha_mode() is not called, libpng assumes that all
+ * values are unencoded, linear, values and that the output device also has a
+ * linear characteristic.  This is only very rarely correct - it is invariably
+ * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+ * default if you don't know what the right answer is!
+ *
+ * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+ * 10.6) which used a correction table to implement a somewhat lower gamma on an
+ * otherwise sRGB system.
+ *
+ * Both these values are reserved (not simple gamma values) in order to allow
+ * more precise correction internally in the future.
+ *
+ * NOTE: the following values can be passed to either the fixed or floating
+ * point APIs, but the floating point API will also accept floating point
+ * values.

+ *    This is the default libpng handling of the alpha channel - it is not
+ *    pre-multiplied into the color components.  In addition the call states
+ *    that the output is for a sRGB system and causes all PNG files without gAMA
+ *    chunks to be assumed to be encoded using sRGB.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ *    In this case the output is assumed to be something like an sRGB conformant

+ *    early Mac systems behaved.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
+ *    This is the classic Jim Blinn approach and will work in academic
+ *    environments where everything is done by the book.  It has the shortcoming
+ *    of assuming that input PNG data with no gamma information is linear - this
+ *    is unlikely to be correct unless the PNG files where generated locally.
+ *    Most of the time the output precision will be so low as to show
+ *    significant banding in dark areas of the image.
+ *
+ * png_set_expand_16(pp);
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+ *    This is a somewhat more realistic Jim Blinn inspired approach.  PNG files
+ *    are assumed to have the sRGB encoding if not marked with a gamma value and
+ *    the output is always 16 bits per component.  This permits accurate scaling
+ *    and processing of the data.  If you know that your input PNG files were
+ *    generated locally you might need to replace PNG_DEFAULT_sRGB with the
+ *    correct value for your system.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+ *    If you just need to composite the PNG image onto an existing background
+ *    and if you control the code that does this you can use the optimization
+ *    setting.  In this case you just copy completely opaque pixels to the
+ *    output.  For pixels that are not completely transparent (you just skip
+ *    those) you do the composition math using png_composite or png_composite_16
+ *    below then encode the resultant 8-bit or 16-bit values to match the output
+ *    encoding.
+ *
+ * Other cases
+ *    If neither the PNG nor the standard linear encoding work for you because
+ *    of the software or hardware you use then you have a big problem.  The PNG
+ *    case will probably result in halos around the image.  The linear encoding
+ *    will probably result in a washed out, too bright, image (it's actually too
+ *    contrasty.)  Try the ALPHA_OPTIMIZED mode above - this will probably
+ *    substantially reduce the halos.  Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ *    This option will also reduce the halos, but there will be slight dark
+ *    halos round the opaque parts of the image where the background is light.
+ *    In the OPTIMIZED mode the halos will be light halos where the background
+ *    is dark.  Take your pick - the halos are unavoidable unless you can get
+ *    your hardware/software fixed!  (The OPTIMIZED approach is slightly
+ *    faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ *    If you have PNG files with no gamma information png_set_alpha_mode allows
+ *    you to provide a default gamma, but it also sets the ouput gamma to the
+ *    matching value.  If you know your PNG files have a gamma that doesn't
+ *    match the output you can take advantage of the fact that
+ *    png_set_alpha_mode always sets the output gamma but only sets the PNG
+ *    default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ *    The first call sets both the default and the output gamma values, the
+ *    second call overrides the output gamma without changing the default.  This
+ *    is easier than achieving the same effect with png_set_gamma.  You must use
+ *    PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ *    fire if more than one call to png_set_alpha_mode and png_set_background is
+ *    made in the same read operation, however multiple calls with PNG_ALPHA_PNG
+ *    are ignored.

+/* Provide the default handling for all unknown chunks or, optionally, for

+ *
+ * NOTE: prior to 1.6.0 the handling specified for particular chunks on read was
+ * ignored and the default was used, the per-chunk setting only had an effect on
+ * write.  If you wish to have chunk-specific handling on read in code that must
+ * work on earlier versions you must use a user chunk callback to specify the
+ * desired handling (keep or discard.)
+ *
+ * The 'keep' parameter is a PNG_HANDLE_CHUNK_ value as listed below.  The
+ * parameter is interpreted as follows:
+ *
+ * READ:
+ *    PNG_HANDLE_CHUNK_AS_DEFAULT:
+ *       Known chunks: do normal libpng processing, do not keep the chunk (but
+ *          see the comments below about PNG_HANDLE_AS_UNKNOWN_SUPPORTED)
+ *       Unknown chunks: for a specific chunk use the global default, when used
+ *          as the default discard the chunk data.
+ *    PNG_HANDLE_CHUNK_NEVER:
+ *       Discard the chunk data.
+ *    PNG_HANDLE_CHUNK_IF_SAFE:
+ *       Keep the chunk data if the chunk is not critical else raise a chunk
+ *       error.
+ *    PNG_HANDLE_CHUNK_ALWAYS:
+ *       Keep the chunk data.
+ *
+ * If the chunk data is saved it can be retrieved using png_get_unknown_chunks,
+ * below.  Notice that specifying "AS_DEFAULT" as a global default is equivalent
+ * to specifying "NEVER", however when "AS_DEFAULT" is used for specific chunks
+ * it simply resets the behavior to the libpng default.
+ *
+ * INTERACTION WTIH USER CHUNK CALLBACKS:
+ * The per-chunk handling is always used when there is a png_user_chunk_ptr
+ * callback and the callback returns 0; the chunk is then always stored *unless*
+ * it is critical and the per-chunk setting is other than ALWAYS.  Notice that
+ * the global default is *not* used in this case.  (In effect the per-chunk
+ * value is incremented to at least IF_SAFE.)
+ *
+ * IMPORTANT NOTE: this behavior will change in libpng 1.7 - the global and
+ * per-chunk defaults will be honored.  If you want to preserve the current
+ * behavior when your callback returns 0 you must set PNG_HANDLE_CHUNK_IF_SAFE
+ * as the default - if you don't do this libpng 1.6 will issue a warning.
+ *
+ * If you want unhandled unknown chunks to be discarded in libpng 1.6 and
+ * earlier simply return '1' (handled).
+ *
+ * PNG_HANDLE_AS_UNKNOWN_SUPPORTED:
+ *    If this is *not* set known chunks will always be handled by libpng and
+ *    will never be stored in the unknown chunk list.  Known chunks listed to
+ *    png_set_keep_unknown_chunks will have no effect.  If it is set then known
+ *    chunks listed with a keep other than AS_DEFAULT will *never* be processed
+ *    by libpng, in addition critical chunks must either be processed by the
+ *    callback or saved.
+ *
+ *    The IHDR and IEND chunks must not be listed.  Because this turns off the
+ *    default handling for chunks that would otherwise be recognized the
+ *    behavior of libpng transformations may well become incorrect!
+ *
+ * WRITE:
+ *    When writing chunks the options only apply to the chunks specified by
+ *    png_set_unknown_chunks (below), libpng will *always* write known chunks
+ *    required by png_set_ calls and will always write the core critical chunks
+ *    (as required for PLTE).
+ *
+ *    Each chunk in the png_set_unknown_chunks list is looked up in the
+ *    png_set_keep_unknown_chunks list to find the keep setting, this is then
+ *    interpreted as follows:
+ *
+ *    PNG_HANDLE_CHUNK_AS_DEFAULT:
+ *       Write safe-to-copy chunks and write other chunks if the global
+ *       default is set to _ALWAYS, otherwise don't write this chunk.
+ *    PNG_HANDLE_CHUNK_NEVER:
+ *       Do not write the chunk.
+ *    PNG_HANDLE_CHUNK_IF_SAFE:
+ *       Write the chunk if it is safe-to-copy, otherwise do not write it.
+ *    PNG_HANDLE_CHUNK_ALWAYS:
+ *       Write the chunk.
+ *
+ * Note that the default behavior is effectively the opposite of the read case -
+ * in read unknown chunks are not stored by default, in write they are written
+ * by default.  Also the behavior of PNG_HANDLE_CHUNK_IF_SAFE is very different
+ * - on write the safe-to-copy bit is checked, on read the critical bit is
+ * checked and on read if the chunk is critical an error will be raised.
+ *
+ * num_chunks:
+ * ===========
+ *    If num_chunks is positive, then the "keep" parameter specifies the manner
+ *    for handling only those chunks appearing in the chunk_list array,
+ *    otherwise the chunk list array is ignored.
+ *
+ *    If num_chunks is 0 the "keep" parameter specifies the default behavior for
+ *    unknown chunks, as described above.
+ *
+ *    If num_chunks is negative, then the "keep" parameter specifies the manner
+ *    for handling all unknown chunks plus all chunks recognized by libpng
+ *    except for the IHDR, PLTE, tRNS, IDAT, and IEND chunks (which continue to

+/*******************************************************************************
+ *  SIMPLIFIED API
+ *******************************************************************************
+ *
+ * Please read the documentation in libpng-manual.txt (TODO: write said
+ * documentation) if you don't understand what follows.
+ *
+ * The simplified API hides the details of both libpng and the PNG file format
+ * itself.  It allows PNG files to be read into a very limited number of
+ * in-memory bitmap formats or to be written from the same formats.  If these
+ * formats do not accomodate your needs then you can, and should, use the more
+ * sophisticated APIs above - these support a wide variety of in-memory formats
+ * and a wide variety of sophisticated transformations to those formats as well
+ * as a wide variety of APIs to manipulate ancillary information.
+ *
+ * To read a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure (see below) on the stack and set the
+ *    version field to PNG_IMAGE_VERSION.
+ * 2) Call the appropriate png_image_begin_read... function.
+ * 3) Set the png_image 'format' member to the required sample format.
+ * 4) Allocate a buffer for the image and, if required, the color-map.
+ * 5) Call png_image_finish_read to read the image and, if required, the
+ *    color-map into your buffers.
+ *
+ * There are no restrictions on the format of the PNG input itself; all valid
+ * color types, bit depths, and interlace methods are acceptable, and the
+ * input image is transformed as necessary to the requested in-memory format
+ * during the png_image_finish_read() step.  The only caveat is that if you
+ * request a color-mapped image from a PNG that is full-color or makes
+ * complex use of an alpha channel the transformation is extremely lossy and the
+ * result may look terrible.
+ *
+ * To write a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure on the stack and memset() it to all zero.
+ * 2) Initialize the members of the structure that describe the image, setting
+ *    the 'format' member to the format of the image samples.
+ * 3) Call the appropriate png_image_write... function with a pointer to the
+ *    image and, if necessary, the color-map to write the PNG data.
+ *
+ * png_image is a structure that describes the in-memory format of an image
+ * when it is being read or defines the in-memory format of an image that you
+ * need to write:

+ * 2: A gray/luminance channel and an alpha channel (GA).
+ * 3: Three red, green, blue color channels (RGB).
+ * 4: Three color channels and an alpha channel (RGBA).
+ *
+ * The components are encoded in one of two ways:
+ *
+ * a) As a small integer, value 0..255, contained in a single byte.  For the
+ * alpha channel the original value is simply value/255.  For the color or
+ * luminance channels the value is encoded according to the sRGB specification
+ * and matches the 8-bit format expected by typical display devices.
+ *
+ * The color/gray channels are not scaled (pre-multiplied) by the alpha
+ * channel and are suitable for passing to color management software.
+ *
+ * b) As a value in the range 0..65535, contained in a 2-byte integer.  All
+ * channels can be converted to the original value by dividing by 65535; all
+ * channels are linear.  Color channels use the RGB encoding (RGB end-points) of
+ * the sRGB specification.  This encoding is identified by the
+ * PNG_FORMAT_FLAG_LINEAR flag below.
+ *
+ * When the simplified API needs to convert between sRGB and linear colorspaces,
+ * the actual sRGB transfer curve defined in the sRGB specification (see the
+ * article at http://en.wikipedia.org/wiki/SRGB) is used, not the gamma=1/2.2
+ * approximation used elsewhere in libpng.
+ *
+ * When an alpha channel is present it is expected to denote pixel coverage
+ * of the color or luminance channels and is returned as an associated alpha
+ * channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+ * value.
+ *
+ * The samples are either contained directly in the image data, between 1 and 8
+ * bytes per pixel according to the encoding, or are held in a color-map indexed
+ * by bytes in the image data.  In the case of a color-map the color-map entries
+ * are individual samples, encoded as above, and the image data has one byte per
+ * pixel to select the relevant sample from the color-map.
+ */

+/* PNG_FORMAT_*
+ *
+ * #defines to be used in png_image::format.  Each #define identifies a
+ * particular layout of sample data and, if present, alpha values.  There are
+ * separate defines for each of the two component encodings.
+ *
+ * A format is built up using single bit flag values.  All combinations are
+ * valid.  Formats can be built up from the flag values or you can use one of
+ * the predefined values below.  When testing formats always use the FORMAT_FLAG
+ * macros to test for individual features - future versions of the library may
+ * add new flags.
+ *
+ * When reading or writing color-mapped images the format should be set to the

+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line.  For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer.  This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI    Calling convention for exported functions.
+ * PNGCBAPI  Calling convention for user provided (callback) functions.
+ * PNGCAPI   Calling convention used by the ANSI-C library (required
+ *           for longjmp callbacks and sometimes used internally to
+ *           specify the calling convention for zlib).
+ *
+ * These macros should never be overridden.  If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ *                This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ *                the 'C' calling convention (from PNGCAPI) for
+ *                callbacks (PNGCBAPI).  This is no longer required
+ *                in any known environment - if it has to be used
+ *                please post an explanation of the problem to the
+ *                libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C
+ * calling convention, at present this just means the above cases
+ * (x86 DOS/Windows sytems) and, even then, this does not apply to
+ * Cygwin running on those systems.
+ *
+ * Note that the value must be defined in pnglibconf.h so that what
+ * the application uses to call the library matches the conventions
+ * set when building the library.
+ */
+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export.  The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols.  On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way.  Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it.  This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one.  For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ *            the build or imported if PNG_USE_DLL is set - compiler
+ *            and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ *                       'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ *                make a symbol exported from the DLL.  Not used in the
+ *                public header files; see pngpriv.h for how it is used
+ *                in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ *                from a DLL - used to define PNG_IMPEXP when
+ *                PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings

+Libfuse for Android
+
+FUSE[1] is a framework to develop userspace file systems for linux. Since Android is based on linux, it won't be too difficult to port libfuse to Android.
+
+The main problem of building and running libfuse on Android is that the bionic c library lacks support for pthread_cancel(), which is necessary for libfuse multi-thread code. This stackoverflow entry[2] has suggested a solution, which uses SIGUSR1 as an alternative. It seems to work.
+
+Libfuse can be build with Android NDK[3]. If success, you will get libfuse.a and an example program fusexmp. To run the example, the android kernel should be built with FUSE kernel support.

+ * Option description
+ *
+ * This structure describes a single option, and action associated
+ * with it, in case it matches.
+ *
+ * More than one such match may occur, in which case the action for
+ * each match is executed.
+ *
+ * There are three possible actions in case of a match:
+ *
+ * i) An integer (int or unsigned) variable determined by 'offset' is
+ *    set to 'value'
+ *
+ * ii) The processing function is called, with 'value' as the key
+ *
+ * iii) An integer (any) or string (char *) variable determined by
+ *    'offset' is set to the value of an option parameter
+ *
+ * 'offset' should normally be either set to
+ *
+ *  - 'offsetof(struct foo, member)'  actions i) and iii)
+ *
+ *  - -1			      action ii)
+ *
+ * The 'offsetof()' macro is defined in the <stddef.h> header.
+ *
+ * The template determines which options match, and also have an
+ * effect on the action.  Normally the action is either i) or ii), but
+ * if a format is present in the template, then action iii) is
+ * performed.
+ *
+ * The types of templates are:
+ *
+ * 1) "-x", "-foo", "--foo", "--foo-bar", etc.	These match only
+ *   themselves.  Invalid values are "--" and anything beginning
+ *   with "-o"
+ *
+ * 2) "foo", "foo-bar", etc.  These match "-ofoo", "-ofoo-bar" or
+ *    the relevant option in a comma separated option list
+ *
+ * 3) "bar=", "--foo=", etc.  These are variations of 1) and 2)
+ *    which have a parameter
+ *
+ * 4) "bar=%s", "--foo=%lu", etc.  Same matching as above but perform
+ *    action iii).
+ *
+ * 5) "-x ", etc.  Matches either "-xparam" or "-x param" as
+ *    two separate arguments
+ *
+ * 6) "-x %s", etc.  Combination of 4) and 5)
+ *
+ * If the format is "%s", memory is allocated for the string unlike
+ * with scanf().

+    // Memory pool

+    

+    //! This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation.

+    //! In most cases, you will not need to use this class directly. 

+    //! However, if you need to create nodes manually or modify names/values of nodes, 

+    //! you are encouraged to use memory_pool of relevant xml_document to allocate the memory. 

+    //! Not only is this faster than allocating them by using <code>new</code> operator, 

+    //! but also their lifetime will be tied to the lifetime of document, 

+    //! possibly simplyfing memory management. 

+    //! <br><br>

+    //! Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool. 

+    //! You can also call allocate_string() function to allocate strings.

+    //! Such strings can then be used as names or values of nodes without worrying about their lifetime.

+    //! Note that there is no <code>free()</code> function -- all allocations are freed at once when clear() function is called, 

+    //! or when the pool is destroyed.

+    //! <br><br>

+    //! It is also possible to create a standalone memory_pool, and use it 

+    //! to allocate nodes, whose lifetime will not be tied to any document.

+    //! <br><br>

+    //! Pool maintains <code>RAPIDXML_STATIC_POOL_SIZE</code> bytes of statically allocated memory. 

+    //! Until static memory is exhausted, no dynamic memory allocations are done.

+    //! When static memory is exhausted, pool allocates additional blocks of memory of size <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> each,

+    //! by using global <code>new[]</code> and <code>delete[]</code> operators. 

+    //! This behaviour can be changed by setting custom allocation routines. 

+    //! Use set_allocator() function to set them.

+    //! <br><br>

+    //! Allocations for nodes, attributes and strings are aligned at <code>RAPIDXML_ALIGNMENT</code> bytes.

+    //! This value defaults to the size of pointer on target architecture.

+    //! <br><br>

+    //! To obtain absolutely top performance from the parser,

+    //! it is important that all nodes are allocated from a single, contiguous block of memory.

+    //! Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite considerably.

+    //! If required, you can tweak <code>RAPIDXML_STATIC_POOL_SIZE</code>, <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> and <code>RAPIDXML_ALIGNMENT</code> 

+    //! to obtain best wasted memory to performance compromise.

+    //! To do it, define their values before rapidxml.hpp file is included.

+ * SECTION:cache
+ * @title: Cache
+ * @short_description: basic routines to work with libblkid cache
+ *
+ * Block device information is normally kept in a cache file blkid.tab and is
+ * verified to still be valid before being returned to the user (if the user has
+ * read permission on the raw block device, otherwise not).  The cache file also
+ * allows unprivileged users (normally anyone other than root, or those not in the
+ * "disk" group) to locate devices by label/id.  The standard location of the
+ * cache file can be overridden by the environment variable BLKID_FILE.
+ *
+ * In situations where one is getting information about a single known device, it
+ * does not impact performance whether the cache is used or not (unless you are
+ * not able to read the block device directly).  If you are dealing with multiple
+ * devices, use of the cache is highly recommended (even if empty) as devices will
+ * be scanned at most one time and the on-disk cache will be updated if possible.
+ * There is rarely a reason not to use the cache.
+ *
+ * In some cases (modular kernels), block devices are not even visible until after
+ * they are accessed the first time, so it is critical that there is some way to
+ * locate these devices without enumerating only visible devices, so the use of
+ * the cache file is required in this situation.

+ *  COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or
+ *  code or tables extracted from it, as desired without restriction.
+ *
+ *  First, the polynomial itself and its table of feedback terms.  The
+ *  polynomial is
+ *  X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ *  Note that we take it "backwards" and put the highest-order term in
+ *  the lowest-order bit.  The X^32 term is "implied"; the LSB is the
+ *  X^31 term, etc.  The X^0 term (usually shown as "+1") results in
+ *  the MSB being 1.
+ *
+ *  Note that the usual hardware shift register implementation, which
+ *  is what we're using (we're merely optimizing it by doing eight-bit
+ *  chunks at a time) shifts bits into the lowest-order term.  In our
+ *  implementation, that means shifting towards the right.  Why do we
+ *  do it this way?  Because the calculated CRC must be transmitted in
+ *  order from highest-order term to lowest-order term.  UARTs transmit
+ *  characters in order from LSB to MSB.  By storing the CRC this way,
+ *  we hand it to the UART in the order low-byte to high-byte; the UART
+ *  sends each low-bit to hight-bit; and the result is transmission bit
+ *  by bit from highest- to lowest-order term without requiring any bit
+ *  shuffling on our part.  Reception works similarly.
+ *
+ *  The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ *      The table can be generated at runtime if desired; code to do so
+ *      is shown later.  It might not be obvious, but the feedback
+ *      terms simply represent the results of eight shift/xor opera-
+ *      tions for all combinations of data and CRC register values.
+ *
+ *      The values must be right-shifted by eight bits by the "updcrc"
+ *      logic; the shift must be unsigned (bring in zeroes).  On some
+ *      hardware you could probably optimize the shift in assembler by
+ *      using byte-swap instructions.

+ * @title: Tags and Spec evaluation
+ * @short_description: top-level API for LABEL and UUID evaluation.
+ *
+ * This API provides very simple and portable way how evaluate LABEL and UUID
+ * tags.  The blkid_evaluate_tag() and blkid_evaluate_spec() work on 2.4 and
+ * 2.6 systems and on systems with or without udev. Currently, the libblkid
+ * library supports "udev" and "scan" methods. The "udev" method uses udev
+ * /dev/disk/by-* symlinks and the "scan" method scans all block devices from
+ * the /proc/partitions file. The evaluation could be controlled by the
+ * /etc/blkid.conf config file. The default is to try "udev" and then "scan"
+ * method.
+ *
+ * The blkid_evaluate_tag() also automatically informs udevd when an obsolete
+ * /dev/disk/by-* symlink is detected.
+ *
+ * If you are not sure how translate LABEL or UUID to the device name use this
+ * API.

+ * SECTION: partitions
+ * @title: Partitions probing
+ * @short_description: partitions tables detection and parsing
+ *
+ * This chain supports binary and NAME=value interfaces, but complete PT
+ * description is provided by binary interface only. The libblkid prober is
+ * compatible with kernel partition tables parser. The parser does not return
+ * empty (size=0) partitions or special hidden partitions.
+ *
+ * NAME=value interface, supported tags:
+ *
+ * @PTTYPE: partition table type (dos, gpt, etc.).
+ *
+ * @PART_ENTRY_SCHEME: partition table type
+ *
+ * @PART_ENTRY_NAME: partition name (gpt and mac only)
+ *
+ * @PART_ENTRY_UUID: partition UUID (gpt only)
+ *
+ * @PART_ENTRY_TYPE: partition type, 0xNN (e.g 0x82) or type UUID (gpt only) or type string (mac)
+ *
+ * @PART_ENTRY_FLAGS: partition flags (e.g. boot_ind) or  attributes (e.g. gpt attributes)
+ *
+ * @PART_ENTRY_NUMBER: partition number
+ *
+ * @PART_ENTRY_OFFSET: the begin of the partition
+ *
+ * @PART_ENTRY_SIZE: size of the partition
+ *
+ * @PART_ENTRY_DISK: whole-disk maj:min
+ *
+ * Example:
+ *
+ * <informalexample>
+ *  <programlisting>
+ * blkid_probe pr;
+ * const char *ptname;
+ *
+ * pr = blkid_new_probe_from_filename(devname);
+ * if (!pr)
+ *	err("%s: faild to open device", devname);
+ *
+ * blkid_probe_enable_partitions(pr, TRUE);
+ * blkid_do_fullprobe(pr);
+ *
+ * blkid_probe_lookup_value(pr, "PTTYPE", &ptname, NULL);
+ * printf("%s partition type detected\n", pttype);
+ *
+ * blkid_free_probe(pr);
+ *
+ * // don't forget to check return codes in your code!
+ *  </programlisting>

+ *	err("%s: faild to open device", devname);
+ *
+ * ls = blkid_probe_get_partitions(pr);
+ * nparts = blkid_partlist_numof_partitions(ls);
+ *
+ * for (i = 0; i < nparts; i++) {

+/**
+ * SECTION: lowprobe
+ * @title: Low-level probing
+ * @short_description: low-level prober initialization
+ *
+ * The low-level probing routines always and directly read information from
+ * the selected (see blkid_probe_set_device()) device.
+ *
+ * The probing routines are grouped together into separate chains. Currently,
+ * the library provides superblocks, partitions and topology chains.
+ *
+ * The probing routines is possible to filter (enable/disable) by type (e.g.
+ * fstype "vfat" or partype "gpt") or by usage flags (e.g. BLKID_USAGE_RAID).
+ * These filters are per-chain. Note that always when you touch the chain
+ * filter the current probing position is reset and probing starts from
+ * scratch.  It means that the chain filter should not be modified during
+ * probing, for example in loop where you call blkid_do_probe().
+ *
+ * For more details see the chain specific documentation.
+ *
+ * The low-level API provides two ways how access to probing results.
+ *
+ *   1. The NAME=value (tag) interface. This interface is older and returns all data
+ *      as strings. This interface is generic for all chains.
+ *
+ *   2. The binary interfaces. These interfaces return data in the native formats.
+ *      The interface is always specific to the probing chain.
+ *
+ *  Note that the previous probing result (binary or NAME=value) is always
+ *  zeroized when a chain probing function is called. For example:
+ *
+ * <informalexample>
+ *   <programlisting>
+ *     blkid_probe_enable_partitions(pr, TRUE);
+ *     blkid_probe_enable_superblocks(pr, FALSE);
+ *
+ *     blkid_do_safeprobe(pr);
+ *   </programlisting>
+ * </informalexample>
+ *
+ * overwrites the previous probing result for the partitions chain, the superblocks
+ * result is not modified.
+ */
+
+/**
+ * SECTION: lowprobe-tags
+ * @title: Low-level tags
+ * @short_description: generic NAME=value interface.
+ *
+ * The probing routines inside the chain are mutually exclusive by default --
+ * only few probing routines are marked as "tolerant". The "tolerant" probing
+ * routines are used for filesystem which can share the same device with any
+ * other filesystem. The blkid_do_safeprobe() checks for the "tolerant" flag.
+ *
+ * The SUPERBLOCKS chain is enabled by default. The all others chains is
+ * necessary to enable by blkid_probe_enable_'CHAINNAME'(). See chains specific
+ * documentation.
+ *
+ * The blkid_do_probe() function returns a result from only one probing
+ * routine, and the next call from the next probing routine. It means you need
+ * to call the function in loop, for example:
+ *
+ * <informalexample>
+ *   <programlisting>
+ *	while((blkid_do_probe(pr) == 0)
+ *		... use result ...
+ *   </programlisting>
+ * </informalexample>
+ *
+ * The blkid_do_safeprobe() is the same as blkid_do_probe(), but returns only
+ * first probing result for every enabled chain. This function checks for
+ * ambivalent results (e.g. more "intolerant" filesystems superblocks on the
+ * device).
+ *
+ * The probing result is set of NAME=value pairs (the NAME is always unique).

+ * @title: Superblocks probing
+ * @short_description: filesystems and raids superblocks probing.
+ *
+ * The library API has been originally designed for superblocks probing only.
+ * This is reason why some *deprecated* superblock specific functions don't use
+ * '_superblocks_' namespace in the function name. Please, don't use these
+ * functions in new code.
+ *
+ * The 'superblocks' probers support NAME=value (tags) interface only. The
+ * superblocks probing is enabled by default (and controlled by
+ * blkid_probe_enable_superblocks()).
+ *
+ * Currently supported tags:
+ *
+ * @TYPE: filesystem type
+ *
+ * @SEC_TYPE: secondary filesystem type
+ *
+ * @LABEL: filesystem label
+ *
+ * @LABEL_RAW: raw label from FS superblock
+ *
+ * @UUID: filesystem UUID (lower case)
+ *
+ * @UUID_SUB: subvolume uuid (e.g. btrfs)
+ *
+ * @UUID_RAW: raw UUID from FS superblock
+ *
+ * @EXT_JOURNAL: external journal UUID
+ *
+ * @USAGE:  usage string: "raid", "filesystem", ...
+ *
+ * @VERSION: filesystem version
+ *
+ * @MOUNT: cluster mount name (?) -- ocfs only
+ *
+ * @SBMAGIC: super block magic string
+ *
+ * @SBMAGIC_OFFSET: offset of SBMAGIC
+ *
+ * @FSSIZE: size of filessystem [not-implemented yet]
+ *
+ * @SYSTEM_ID: ISO9660 system identifier
+ *
+ * @PUBLISHER_ID: ISO9660 publisher identifier

+ * @title: Topology information
+ * @short_description: block device topology information.
+ *
+ * The topology chain provides details about Linux block devices, for more
+ * information see:
+ *
+ *      Linux kernel Documentation/ABI/testing/sysfs-block
+ *
+ * NAME=value (tags) interface is enabled by blkid_probe_enable_topology(),
+ * and provides:
+ *
+ * @LOGICAL_SECTOR_SIZE: this is the smallest unit the storage device can
+ *                       address. It is typically 512 bytes.
+ *
+ * @PHYSICAL_SECTOR_SIZE: this is the smallest unit a physical storage device
+ *                        can write atomically. It is usually the same as the
+ *                        logical sector size but may be bigger.
+ *
+ * @MINIMUM_IO_SIZE: minimum size which is the device's preferred unit of I/O.
+ *                   For RAID arrays it is often the stripe chunk size.
+ *
+ * @OPTIMAL_IO_SIZE: usually the stripe width for RAID or zero. For RAID arrays
+ *                   it is usually the stripe width or the internal track size.
+ *
+ * @ALIGNMENT_OFFSET: indicates how many bytes the beginning of the device is
+ *                    offset from the disk's natural alignment.
+ *
+ * The NAME=value tags are not defined when the corresponding topology value
+ * is zero. The MINIMUM_IO_SIZE should be always defined if kernel provides
+ * topology information.

+libtar 1.0.2 - 6/21/00
+------------
+
+- tar_set_file_perms() now calls chown() only if the effective user ID is 0
+  (workaround for IRIX and HP-UX, which allow file giveaways)
+
+- tar_set_file_perms() now calls chmod() or lchmod() after chown()
+  (this fixes a problem with extracting setuid files under Linux)
+
+- removed calls to fchown() and fchmod() from tar_extract_regfile()
+
+- fixed bugs in th_read() which didn't set errno properly
+
+- removed various unused variables
+
+----------------------------------------------------------------------
+
+libtar 1.0.1 - 4/1/00
+------------
+
+- removed libgen.h include from dirname and basename compat code
+
+- added lib/fnmatch.c compatability module from OpenBSD
+
+- fixed several objdirs bugs in libtar/Makefile.in
+
+- misc Makefile changes (added $CPPFLAGS support, added -o flag to compile
+  commands, use $CFLAGS on link line, etc)
+
+- removed "inline" keyword from all source files to prevent portability
+  problems
+
+- updated README
+
+----------------------------------------------------------------------
+
+libtar 1.0 - 1/2/00
+----------
+
+- various portability fixes
+
+- "make install" now runs mkencap and epkg if they're available
+
+- libmisc is now integrated into libtar
+
+----------------------------------------------------------------------
+
+libtar 0.5.6 beta - 12/16/99
+-----------------
+

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+libtar - C library for manipulating tar files
+======
+
+libtar is a library for manipulating tar files from within C programs.
+Here are some of its features:
+
+  * Handles both POSIX tar file format and the GNU extensions.
+  * API provides functions for easy use, such as tar_extract_all().
+  * Also provides functions for more granular use, such as 
+    tar_append_regfile().
+
+
+Installation
+------------
+
+To build libtar, you should be able to simply run these commands:
+
+   ./configure
+   make
+   make install
+
+
+Encap Package Support
+---------------------
+
+To build this software as an Encap package, you can pass the
+--enable-encap option to configure.  This will be automatically
+enabled if the epkg or mkencap programs are detected on the system,
+but can be overridden by the --disable-encap option.
+
+When building an Encap package, the configure script will automatically
+adjust the installation prefix to use an appropriate Encap package
+directory.  It does this using a heuristic algorithm which examines the
+values of the ${ENCAP_SOURCE} and ${ENCAP_TARGET} environment variables
+and the argument to configure's --prefix option.
+
+If mkencap was detected on the system, it will be automatically run during
+"make install".  By default, epkg will also be run, but this can be
+inhibited with the --disable-epkg-install configure option.
+
+For information on the Encap package management system, see the WSG
+Encap Archive:
+
+   http://www.encap.org/
+
+
+zlib Support
+------------
+
+The configure script will attempt to find the zlib library on your system
+for use with the libtar driver program.  The zlib package is available from:
+
+   http://www.gzip.org/zlib/
+
+If zlib is installed on your system, but you do not wish to use it,
+specify the --without-zlib option when you invoke configure.
+
+
+More Information
+----------------
+
+For documentation of the libtar API, see the enclosed manpages.  For more
+information on the libtar package, see:
+
+   http://www-dev.cites.uiuc.edu/libtar/
+
+Source code for the latest version of libtar will be available there, as
+well as Encap binary distributions for many common platforms.
+
+
+Supported Platforms
+-------------------
+
+I develop and test libtar on the following platforms:
+
+   AIX 4.3.3 and 5.1
+   HP-UX 11.00
+   IRIX 6.5
+   RedHat Linux 7.2
+   Solaris 8 and 9
+
+It should also build on the following platforms, but I do not actively
+support them:
+
+   AIX 3.2.5
+   AIX 4.2.1
+   Cygwin
+   FreeBSD
+   HP-UX 10.20
+   Linux/libc5
+   OpenBSD
+   Solaris 2.5
+   Solaris 2.6
+   Solaris 7
+
+If you successfully build libtar on another platform, please email me a
+patch and/or configuration information.
+
+
+Compatibility Code
+------------------
+
+libtar depends on some library calls which are not available or not
+usable on some platforms.  To accomodate these systems, I've included
+a version of these calls in the compat subdirectory.
+
+I've slightly modified these functions for integration into this source
+tree, but the functionality has not been modified from the original
+source.  Please note that while this code should work for you, I didn't
+write it, so please don't send me bug reports on it.

+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh.  This sort of thing is always nasty do deal with.  Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formated the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.
+ * 
+ *  Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ *    The PGP code was using unsigned hexadecimal formats. 
+ *    Unfortunately, unsigned formats simply didn't work.
+ *
+ *  Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ *    The original code assumed that both snprintf() and vsnprintf() were
+ *    missing.  Some systems only have snprintf() but not vsnprintf(), so
+ *    the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ *  Chris Frey <cdfrey@foursquare.net> 2012/09/05
+ *    Removed varargs.h and all dependency on it.

+ * @dst_rect:	Destination rectangle, the position and size of image on screen.
+ *		This should always be within panel boundaries.
+ * @z_order:	Blending stage to occupy in display, if multiple layers are

+ *		less than this layer will not be blended and will be replaced
+ *		by the background border color.
+ * @alpha:	Used to set plane opacity. The range can be from 0-255, where
+ *		0 means completely transparent and 255 means fully opaque.
+ * @transp_mask: Color used as color key for transparency. Any pixel in fetched

+ * @alpha:	Used to set plane opacity. The range can be from 0-255, where

+
+Introduction
+------------
+
+OpenAES is an open source implementation of the Advanced Encryption
+Standard.  It is distributed as a portable, lightweight C library that can
+be easily integrated into applications.
+
+Compiling
+---------
+
+OpenAES has been tested with the GCC as well as VC compilers.  It is
+necessary to compile the source files located in ./src, and to add ./inc to
+the include paths.
+
+If you are building with OAES_HAVE_ISAAC defined (true by default), then
+you also need to link in the source files under ./src/isaac and also add
+./src/isaac to the include paths.
+
+You may edit ./inc/oaes_config.h to modify build options.
+
+CMake 2.8.0 can be used to build the test programs on different platforms.
+
+In a Linux command line terminal type:
+
+cmake .
+make
+
+In Windows, in a Visual Studio command line window type:
+
+cmake . -G "NMake Makefiles"
+nmake
+
+Usage
+-----
+
+Usage is described in the header file ./inc/oaes_lib.h.
+
+Samples
+-------
+
+Samples applications are provided in the /test folder.

+pigz 2.2.5 (xx Apr 2012) by Mark Adler
+
+pigz, which stands for Parallel Implementation of GZip, is a fully functional
+replacement for gzip that exploits multiple processors and multiple cores to
+the hilt when compressing data.
+
+pigz was written by Mark Adler, and uses the zlib and pthread libraries.
+
+This version of pigz is written to be portable across Unix-style operating
+systems that provide the zlib and pthread libraries.
+
+Type "make" in this directory to build the "pigz" executable.  You can then
+install the executable wherever you like in your path (e.g. /usr/local/bin/).
+Type "pigz" to see the command help and all of the command options.
+
+The latest version of pigz can be found at http://zlib.net/pigz/ .  You need
+zlib version 1.2.3 or later to compile pigz.  You can find the latest version
+of zlib at http://zlib.net/ .  You can look in pigz.c for the change history.
+
+Questions, comments, bug reports, fixes, etc. can be emailed to Mark at his
+address in the license below.

+.SH DESCRIPTION
+.I Pigz
+compresses using threads to make use of multiple processors and cores.
+The input is broken up into 128 KB chunks with each compressed in parallel.
+The individual check value for each chunk is also calculated in parallel.
+The compressed data is written in order to the output, and a combined check
+value is calculated from the individual check values.
+.PP
+The compressed data format generated is in the gzip, zlib, or single-entry
+zip format using the deflate compression method.  The compression produces
+partial raw deflate streams which are concatenated by a single write thread
+and wrapped with the appropriate header and trailer, where the trailer
+contains the combined check value.
+.PP
+Each partial raw deflate stream is terminated by an empty stored block
+(using the Z_SYNC_FLUSH option of zlib), in order to end that partial bit
+stream at a byte boundary.  That allows the partial streams to be
+concatenated simply as sequences of bytes.  This adds a very small four to
+five byte overhead to the output for each input chunk.
+.PP
+The default input block size is 128K, but can be changed with the
+.B -b
+option.  The number of compress threads is set by default to the number
+of online processors,
+which can be changed using the
+.B -p
+option.  Specifying
+.B -p 1
+avoids the use of threads entirely.
+.PP
+The input blocks, while compressed independently, have the last 32K of the
+previous block loaded as a preset dictionary to preserve the compression
+effectiveness of deflating in a single thread.  This can be turned off using
+the
+.B -i
+or
+.B --independent
+option, so that the blocks can be decompressed
+independently for partial error recovery or for random access.
+.PP
+Decompression can't be parallelized, at least not without specially prepared
+deflate streams for that purpose.  As a result,
+.I pigz
+uses a single thread
+(the main thread) for decompression, but will create three other threads for
+reading, writing, and check calculation, which can speed up decompression
+under some circumstances.  Parallel decompression can be turned off by
+specifying one process
+(
+.B -dp 1
+or
+.B -tp 1
+).
+.PP
+Compressed files can be restored to their original form using
+.I pigz -d
+or
+.I unpigz.

+/*
+   pigz compresses using threads to make use of multiple processors and cores.
+   The input is broken up into 128 KB chunks with each compressed in parallel.
+   The individual check value for each chunk is also calculated in parallel.
+   The compressed data is written in order to the output, and a combined check
+   value is calculated from the individual check values.
+
+   The compressed data format generated is in the gzip, zlib, or single-entry
+   zip format using the deflate compression method.  The compression produces
+   partial raw deflate streams which are concatenated by a single write thread
+   and wrapped with the appropriate header and trailer, where the trailer
+   contains the combined check value.
+
+   Each partial raw deflate stream is terminated by an empty stored block
+   (using the Z_SYNC_FLUSH option of zlib), in order to end that partial bit
+   stream at a byte boundary, unless that partial stream happens to already end
+   at a byte boundary (the latter requires zlib 1.2.6 or later).  Ending on a
+   byte boundary allows the partial streams to be concatenated simply as
+   sequences of bytes.  This adds a very small four to five byte overhead
+   (average 3.75 bytes) to the output for each input chunk.
+
+   The default input block size is 128K, but can be changed with the -b option.
+   The number of compress threads is set by default to 8, which can be changed
+   using the -p option.  Specifying -p 1 avoids the use of threads entirely.
+   pigz will try to determine the number of processors in the machine, in which
+   case if that number is two or greater, pigz will use that as the default for
+   -p instead of 8.
+
+   The input blocks, while compressed independently, have the last 32K of the
+   previous block loaded as a preset dictionary to preserve the compression
+   effectiveness of deflating in a single thread.  This can be turned off using
+   the --independent or -i option, so that the blocks can be decompressed
+   independently for partial error recovery or for random access.
+
+   Decompression can't be parallelized, at least not without specially prepared
+   deflate streams for that purpose.  As a result, pigz uses a single thread
+   (the main thread) for decompression, but will create three other threads for
+   reading, writing, and check calculation, which can speed up decompression
+   under some circumstances.  Parallel decompression can be turned off by
+   specifying one process (-dp 1 or -tp 1).
+
+   pigz requires zlib 1.2.1 or later to allow setting the dictionary when doing
+   raw deflate.  Since zlib 1.2.3 corrects security vulnerabilities in zlib
+   version 1.2.1 and 1.2.2, conditionals check for zlib 1.2.3 or later during
+   the compilation of pigz.c.  zlib 1.2.4 includes some improvements to
+   Z_FULL_FLUSH and deflateSetDictionary() that permit identical output for
+   pigz with and without threads, which is not possible with zlib 1.2.3.  This
+   may be important for uses of pigz -R where small changes in the contents
+   should result in small changes in the archive for rsync.  Note that due to
+   the details of how the lower levels of compression result in greater speed,
+   compression level 3 and below does not permit identical pigz output with
+   and without threads.
+
+   pigz uses the POSIX pthread library for thread control and communication,
+   through the yarn.h interface to yarn.c.  yarn.c can be replaced with
+   equivalent implementations using other thread libraries.  pigz can be
+   compiled with NOTHREAD #defined to not use threads at all (in which case
+   pigz will not be able to live up to the "parallel" in its name).
+ */
+
+/*
+   Details of parallel compression implementation:
+
+   When doing parallel compression, pigz uses the main thread to read the input
+   in 'size' sized chunks (see -b), and puts those in a compression job list,
+   each with a sequence number to keep track of the ordering.  If it is not the
+   first chunk, then that job also points to the previous input buffer, from
+   which the last 32K will be used as a dictionary (unless -i is specified).
+   This sets a lower limit of 32K on 'size'.
+
+   pigz launches up to 'procs' compression threads (see -p).  Each compression
+   thread continues to look for jobs in the compression list and perform those
+   jobs until instructed to return.  When a job is pulled, the dictionary, if
+   provided, will be loaded into the deflate engine and then that input buffer
+   is dropped for reuse.  Then the input data is compressed into an output
+   buffer that grows in size if necessary to hold the compressed data. The job
+   is then put into the write job list, sorted by the sequence number. The
+   compress thread however continues to calculate the check value on the input
+   data, either a CRC-32 or Adler-32, possibly in parallel with the write
+   thread writing the output data.  Once that's done, the compress thread drops
+   the input buffer and also releases the lock on the check value so that the
+   write thread can combine it with the previous check values.  The compress
+   thread has then completed that job, and goes to look for another.
+
+   All of the compress threads are left running and waiting even after the last
+   chunk is processed, so that they can support the next input to be compressed
+   (more than one input file on the command line).  Once pigz is done, it will
+   call all the compress threads home (that'll do pig, that'll do).
+
+   Before starting to read the input, the main thread launches the write thread
+   so that it is ready pick up jobs immediately.  The compress thread puts the
+   write jobs in the list in sequence sorted order, so that the first job in
+   the list is always has the lowest sequence number.  The write thread waits
+   for the next write job in sequence, and then gets that job.  The job still
+   holds its input buffer, from which the write thread gets the input buffer
+   length for use in check value combination.  Then the write thread drops that
+   input buffer to allow its reuse.  Holding on to the input buffer until the
+   write thread starts also has the benefit that the read and compress threads
+   can't get way ahead of the write thread and build up a large backlog of
+   unwritten compressed data.  The write thread will write the compressed data,
+   drop the output buffer, and then wait for the check value to be unlocked
+   by the compress thread.  Then the write thread combines the check value for
+   this chunk with the total check value for eventual use in the trailer.  If
+   this is not the last chunk, the write thread then goes back to look for the
+   next output chunk in sequence.  After the last chunk, the write thread
+   returns and joins the main thread.  Unlike the compress threads, a new write
+   thread is launched for each input stream.  The write thread writes the
+   appropriate header and trailer around the compressed data.
+
+   The input and output buffers are reused through their collection in pools.
+   Each buffer has a use count, which when decremented to zero returns the
+   buffer to the respective pool.  Each input buffer has up to three parallel
+   uses: as the input for compression, as the data for the check value
+   calculation, and as a dictionary for compression.  Each output buffer has
+   only one use, which is as the output of compression followed serially as
+   data to be written.  The input pool is limited in the number of buffers, so
+   that reading does not get way ahead of compression and eat up memory with

+/* rsyncable constants -- RSYNCBITS is the number of bits in the mask for
+   comparison.  For random input data, there will be a hit on average every
+   1<<RSYNCBITS bytes.  So for an RSYNCBITS of 12, there will be an average of
+   one hit every 4096 bytes, resulting in a mean block size of 4096.  RSYNCMASK
+   is the resulting bit mask.  RSYNCHIT is what the hash value is compared to
+   after applying the mask.
+
+   The choice of 12 for RSYNCBITS is consistent with the original rsyncable
+   patch for gzip which also uses a 12-bit mask.  This results in a relatively
+   small hit to compression, on the order of 1.5% to 3%.  A mask of 13 bits can
+   be used instead if a hit of less than 1% to the compression is desired, at
+   the expense of more blocks transmitted for rsync updates.  (Your mileage may
+   vary.)
+
+   This implementation of rsyncable uses a different hash algorithm than what
+   the gzip rsyncable patch uses in order to provide better performance in
+   several regards.  The algorithm is simply to shift the hash value left one
+   bit and exclusive-or that with the next byte.  This is masked to the number
+   of hash bits (RSYNCMASK) and compared to all ones except for a zero in the
+   top bit (RSYNCHIT). This rolling hash has a very small window of 19 bytes
+   (RSYNCBITS+7).  The small window provides the benefit of much more rapid
+   resynchronization after a change, than does the 4096-byte window of the gzip
+   rsyncable patch.
+
+   The comparison value is chosen to avoid matching any repeated bytes or short
+   sequences.  The gzip rsyncable patch on the other hand uses a sum and zero
+   for comparison, which results in certain bad behaviors, such as always
+   matching everywhere in a long sequence of zeros.  Such sequences occur
+   frequently in tar files.
+
+   This hash efficiently discards history older than 19 bytes simply by
+   shifting that data past the top of the mask -- no history needs to be
+   retained to undo its impact on the hash value, as is needed for a sum.
+
+   The choice of the comparison value (RSYNCHIT) has the virtue of avoiding
+   extremely short blocks.  The shortest block is five bytes (RSYNCBITS-7) from
+   hit to hit, and is unlikely.  Whereas with the gzip rsyncable algorithm,
+   blocks of one byte are not only possible, but in fact are the most likely
+   block size.
+
+   Thanks and acknowledgement to Kevin Day for his experimentation and insights
+   on rsyncable hash characteristics that led to some of the choices here.

+
+/* Basic thread operations
+
+   This interface isolates the local operating system implementation of threads
+   from the application in order to facilitate platform independent use of
+   threads.  All of the implementation details are deliberately hidden.
+
+   Assuming adequate system resources and proper use, none of these functions
+   can fail.  As a result, any errors encountered will cause an exit() to be
+   executed.
+
+   These functions allow the simple launching and joining of threads, and the
+   locking of objects and synchronization of changes of objects.  The latter is
+   implemented with a single lock type that contains an integer value.  The
+   value can be ignored for simple exclusive access to an object, or the value
+   can be used to signal and wait for changes to an object.
+
+   -- Arguments --
+
+   thread *thread;          identifier for launched thread, used by join
+   void probe(void *);      pointer to function "probe", run when thread starts
+   void *payload;           single argument passed to the probe function
+   lock *lock;              a lock with a value -- used for exclusive access to
+                            an object and to synchronize threads waiting for
+                            changes to an object
+   long val;                value to set lock, increment lock, or wait for
+   int n;                   number of threads joined
+
+   -- Thread functions --
+
+   thread = launch(probe, payload) - launch a thread -- exit via probe() return
+   join(thread) - join a thread and by joining end it, waiting for the thread
+        to exit if it hasn't already -- will free the resources allocated by
+        launch() (don't try to join the same thread more than once)
+   n = join_all() - join all threads launched by launch() that are not joined
+        yet and free the resources allocated by the launches, usually to clean
+        up when the thread processing is done -- join_all() returns an int with
+        the count of the number of threads joined (join_all() should only be
+        called from the main thread, and should only be called after any calls
+        of join() have completed)
+   destruct(thread) - terminate the thread in mid-execution and join it
+        (depending on the implementation, the termination may not be immediate,
+        but may wait for the thread to execute certain thread or file i/o
+        operations)
+
+   -- Lock functions --
+
+   lock = new_lock(val) - create a new lock with initial value val (lock is
+        created in the released state)
+   possess(lock) - acquire exclusive possession of a lock, waiting if necessary
+   twist(lock, [TO | BY], val) - set lock to or increment lock by val, signal
+        all threads waiting on this lock and then release the lock -- must
+        possess the lock before calling (twist releases, so don't do a
+        release() after a twist() on the same lock)
+   wait_for(lock, [TO_BE | NOT_TO_BE | TO_BE_MORE_THAN | TO_BE_LESS_THAN], val)
+        - wait on lock value to be, not to be, be greater than, or be less than
+        val -- must possess the lock before calling, will possess the lock on
+        return but the lock is released while waiting to permit other threads
+        to use twist() to change the value and signal the change (so make sure
+        that the object is in a usable state when waiting)
+   release(lock) - release a possessed lock (do not try to release a lock that
+        the current thread does not possess)
+   val = peek_lock(lock) - return the value of the lock (assumes that lock is
+        already possessed, no possess or release is done by peek_lock())
+   free_lock(lock) - free the resources allocated by new_lock() (application
+        must assure that the lock is released before calling free_lock())
+
+   -- Memory allocation ---
+
+   yarn_mem(better_malloc, better_free) - set the memory allocation and free
+        routines for use by the yarn routines where the supplied routines have
+        the same interface and operation as malloc() and free(), and may be
+        provided in order to supply thread-safe memory allocation routines or
+        for any other reason -- by default malloc() and free() will be used
+
+   -- Error control --
+
+   yarn_prefix - a char pointer to a string that will be the prefix for any
+        error messages that these routines generate before exiting -- if not
+        changed by the application, "yarn" will be used
+   yarn_abort - an external function that will be executed when there is an
+        internal yarn error, due to out of memory or misuse -- this function
+        may exit to abort the application, or if it returns, the yarn error
+        handler will exit (set to NULL by default for no action)

+# shade@chemlab.org
+#
+# original concept: http://blog.elsdoerfer.name/2009/05/25/android-fix-package-uid-mismatches/
+# implementation by: Cyanogen
+# improved by: ankn, smeat, thenefield, farmatito, rikupw, Kastro
+#
+# v1.1-v1.31r3 - many improvements and concepts from XDA developers.
+# v1.34 through v2.00 -  A lot of frustration [by Kastro]
+# v2.01	- Completely rewrote the script for SPEED, thanks for the input farmatito
+#         /data/data depth recursion is tweaked;
+#         fixed single mode;
+#         functions created for modularity;
+#         logging can be disabled via CLI for more speed;
+#         runtime computation added to end (Runtime: mins secs);
+#         progress (current # of total) added to screen;
+#         fixed CLI argument parsing, now you can have more than one option!;
+#         debug cli option;
+#         verbosity can be disabled via CLI option for less noise;;
+#         [by Kastro, (XDA: k4str0), twitter;mattcarver]
+# v2.02 - ignore com.htc.resources.apk if it exists and minor code cleanups,
+#         fix help text, implement simulated run (-s) [farmatito]
+# v2.03 - fixed chown group ownership output [Kastro]
+# v2.04 - replaced /system/sd with $SD_EXT_DIRECTORY [Firerat]
