Detailed Description

Special re-entrant version of getopt.

Everything is prefixed with bu_, to distinguish it from the various getopt() routines found in libc.

Important note - If bu_getopt() it going to be used more than once, it is necessary to reinitialize bu_optind=1 before beginning on the next argument list.

Definition in file getopt.c.
