+Subject: public domain AT&T getopt source
+Date: 3 Nov 85 19:34:15 GMT
+
+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.
