1993-08-04 21:46:14 +04:00
* Revision 1.2 1993/08/04 17:46:20 brezak
* Changes from nate for gzip'ed sup
*
* Revision 1.1.1.1 1993/05/21 14:52:18 cgd
1993-05-21 18:52:16 +04:00
* initial import of CMU's SUP to NetBSD
*
* Revision 1.6 92/08/11 12:07:38 mrt
* Added use-rel-suffix option corresponding to -u switch.
* [92/07/26 mrt]
*
* Revision 1.5 92/02/08 18:24:19 mja
* Added "keep" supfile option, corresponding to -k switch.
* [92/01/17 vdelvecc]
*
* Revision 1.4 91/05/16 14:49:50 ern
* Change default timeout from none to 3 hours so we don't accumalute
* processes running sups to dead hosts especially for users.
* [91/05/16 14:49:21 ern]
*
*
* 10-Feb-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added timeout to backoff.
*
* 28-Jun-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added code for "release" support. Removed obsolete options.
*
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
* Split off from sup.c
