A problem and a two questions.  First, the problem:

		Script started on Thu Apr  7 18:51:58 1988
		$ grep UNIX /vmunix
		4.3 BSD UNIX #25: 12/12 02:45:12 PM
		$ man getopts
		No manual entry for getopts.
		$ exit

		script done on Thu Apr  7 18:52:34 1988

Second, the questions.  Is a public-domain implementation of "the existing
getopts scheme," or at least a public-domain manual page, available?  And
is the scheme idiot-proof enough to work when executed in directories with
files named, for example, "-l"?
