/*
* sup collection parsing routines
**********************************************************************
* HISTORY
*
* 7-July-93 Nate Williams at Montana State University
* Modified SUP to use gzip based compression when sending files
* across the network to save BandWidth
*
* 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
