There have recently been several requests for a public
domain version of getopt(3), recently.  Thought this
might be worth reposting.

In April of this year, Henry Spencer (utzoo!henry) released a public
domain version of getopt (USG, getopt(3)).  Well, I've been trying to
port some USG dependent software and it didn't seem to work.  The problem
ended up being that the USG version of getopt has some external variables
that aren't mentioned in the documentation.  Anyway, to fix these problems,
I rewrote the public version of getopt.  It has the following advantages:

	-- it includes those "unknown" variables
	-- it's smaller/faster 'cause it doesn't use the formatted
		output conversion routines in section 3 of the UNIX manual.
	-- the error messages are the same as S5's.
	-- it has the same side-effects that S5's has.
	-- the posted bug on how the error messages are flushed has been
		implemented.  (posting by Tony Hansen; pegasus!hansen)

I won't post the man pages since Henry already did; a special note,
it's not documented in the S5 manual that the options ':' and '?' are
illegal.  It should be obvious, but I thought I'd mention it...
This software was derived from binaries of S5 and the S5 man page, and is
(I think?) totally (I'm pretty sure?) compatible with S5 and backward
compatible to Henry's version.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
