/*
** This is part of a changed public domain getopt implementation that
** had the following text on top:
**
** I got this off net.sources from Henry Spencer.
** It is a public domain getopt(3) like in System V.
** I have made the following modifications:
**
** A test main program was added, ifdeffed by GETOPT.
** This main program is a public domain implementation
** of the getopt(1) program like in System V. The getopt
** program can be used to standardize shell option handling.
** e.g. cc -DGETOPT getopt.c -o getopt
