Using getopt to parse multi-argument options

[Roy Smith]

[not strictly a C question, but comp.lang.c seems to be the best place]

	I'm writing a program which will take an optional range, in the
style of graph(1)'s "-x xmin xmax".  How do I tell getopt to parse
something like that?  I suppose I could diddle with optind to make getopt
skip the next argument, but that hardly seems kosher.  The obvious way to
do this would be to have getopt support a syntax like "-r::" which means
the "-r" flag has *two* arguments after it but it's too late now.
