+/*
+	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:
+
+	index(s,c) was added because too many people could
+	not compile getopt without it.
+
+	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
