||
| 26 | * Here's something you've all been waiting for: the AT&T public domain |
||
| 27 | * source for getopt(3). It is the code which was given out at the 1985 |
||
| 28 | * UNIFORUM conference in Dallas. I obtained it by electronic mail |
||
| 29 | * directly from AT&T. The people there assure me that it is indeed |
||
| 30 | * in the public domain. |
