+The contents of this directory are copied from system/core/adb, with
+the following changes:
+
+adb.c
+ - much support for host mode and non-linux OS's stripped out; this
+ version only runs as adbd on the device.
+ - does not setuid/setgid itself (always stays root)
+ - only uses USB transport
+ - references to JDWP removed
+ - main() removed
+
+adb.h
+ - minor changes to match adb.c changes
+
+sockets.c
+ - references to JDWP removed
+
+services.c
+ - all services except echo_service (which is commented out) removed
+ - all host mode support removed
+ - sideload_service() added; this is the only service supported. It
+ receives a single blob of data, writes it to a fixed filename, and
+ makes the process exit.
+
+Android.mk
+ - only builds in adbd mode; builds as static library instead of a
+ standalone executable.
