-/*
- * 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 behavior of this getopt. However, I am not about to
- * post a copy of anything licensed by AT&T.
