* POSIX getopt for Windows
* Code given out at the 1985 UNIFORUM conference in Dallas.

* From std-unix@ut-sally.UUCP (Moderator, John Quarterman) Sun Nov 3 14:34:15 1985
* Relay-Version: version B 2.10.3 4.3bsd-beta 6/6/85; site gatech.CSNET
* Posting-Version: version B 2.10.2 9/18/84; site ut-sally.UUCP
* Path: gatech!akgua!mhuxv!mhuxt!mhuxr!ulysses!allegra!mit-eddie!genrad!panda!talcott!harvard!seismo!ut-sally!std-unix
* From: std-unix@ut-sally.UUCP (Moderator, John Quarterman)
* Newsgroups: mod.std.unix
* Subject: public domain AT&T getopt source
* Message-ID: <3352@ut-sally.UUCP>
* Date: 3 Nov 85 19:34:15 GMT
* Date-Received: 4 Nov 85 12:25:09 GMT
* Organization: IEEE/P1003 Portable Operating System Environment Committee
* Lines: 91
* Approved: jsq@ut-sally.UUC
* Here's something you've all been waiting for: the AT&T public domain
* source for getopt(3). It is the code which was given out at the 1985
* UNIFORUM conference in Dallas. I obtained it by electronic mail
* directly from AT&T. The people there assure me that it is indeed
* in the public domain
* There is no manual page. That is because the one they gave out at
* UNIFORUM was slightly different from the current System V Release 2
* manual page. The difference apparently involved a note about the
* famous rules 5 and 6, recommending using white space between an option
* and its first argument, and not grouping options that have arguments.
* Getopt itself is currently lenient about both of these things White
* space is allowed, but not mandatory, and the last option in a group can
* have an argument. That particular version of the man page evidently
* has no official existence, and my source at AT&T did not send a copy.
* The current SVR2 man page reflects the actual behavor of this getopt.
* However, I am not about to post a copy of anything licensed by AT&T.
