-/**
-* GetOpt is a Java equivalent to the C getopt() library function
-* discussed in man page getopt(3C). It provides command line
-* parsing for Java applications. It supports the most rules of the
-* command line standard (see man page intro(1)) including stacked
-* options such as '-sxm' (which is equivalent to -s -x -m); it
-* handles special '--' option that signifies the end of options.
-* Additionally this implementation of getopt will check for
-* mandatory arguments to options such as in the case of
-* '-d <file>' it will throw a MissingOptArgException if the
-* option argument '<file>' is not included on the commandline.
-* getopt(3C) does not check for this.
