+** u t i l _ g e t o p t
+**
+** Synopsis: Used to parse command line arguments based on a specified
+** syntax. The argument for the current option is stored in
+** the global variable "util_optarg".
+**
+** Parameters: argc - the number of arguments in the array.
+** argv - the argumnet array.
+** opts - option specifier string. Options can be of two forms:
+** boolean flags ( its either there or it isn't ) and
+** flag value pairs in which a flag is always followed
+** by some value. Options which require an argument
+** must be followed by a ":" in the option specifier
+** string. So for a command which can have two boolean
+** flags, "h" and "i", and two argument flags, "t" and
+** "u", the following option specifier string would be
+** used: "hit:u:".
+**
+** Returns: the option character found, or -1 if no more option
+** characters.
+**
+** Constraints: NONE
