**********************************************************************
* HISTORY
* 13-Sep-92 Mary Thompson (mrt) at Carnegie-Mellon University
* Changed name of DEFDIR from /usr/cs to /usr.
*
* 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
*
* $Log: sup.h,v $
* Revision 1.1.1.1 1995/12/26 04:54:47 peter
* Import the unmodified version of the sup that we are using.
* The heritage of this version is not clear. It appears to be NetBSD
* derived from some time ago.
*
* Revision 1.1.1.1 1993/08/21 00:46:34 jkh
* Current sup with compression support.
*
* Revision 1.1.1.1 1993/05/21 14:52:18 cgd
* initial import of CMU's SUP to NetBSD
*
* Revision 1.10 92/08/11 12:06:42 mrt
* Added definition for DEBUGFPORTNUM, the debugging port number.
* Changed so that last and when file names could include
* the relase name if any.
* [92/07/23 mrt]
*
* Revision 1.9 91/04/29 14:39:03 mja
* Reduce MAXCHILDREN from 8 to 3.
*
* Revision 1.8 89/08/23 14:55:30 gm0w
* Moved coll.dir from supservers to supfiles.
* [89/08/23 gm0w]
*
* 18-Mar-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added host=<hostfile> support to releases file.
*
* 27-Dec-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added crosspatch support. Removed nameserver support.
*
* 27-Jun-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added TREELIST and other changes for "release" support.
*
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
* Version 6 of the network protocol, better support to reflect errors
* back to server logfile.
*
* 21-May-87 Chriss Stephens (chriss) at Carnegie Mellon University
* Merged divergent CS and EE versions.
*
* 19-Sep-86 Mike Accetta (mja) at Carnegie-Mellon University
* Added FILESUPTDEFAULT definition.
*
* 07-Jun-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Removed FILESRVBUSYWAIT. Now uses exponential backoff.
*
* 30-May-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added numeric port numbers to use when port names are not in the
* host table.
*
* 04-Jan-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Update protocol version to 5 for name server protocol change to
* allow multiple repositories per collection. Added FILESRVBUSYWAIT
* of 5 minutes. Added FILELOCK file to indicate collections that
* should be exclusively locked when upgraded.
*
* 22-Sep-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Merged 4.1 and 4.2 versions together.
*
* 04-Jun-85 Steven Shafer (sas) at Carnegie-Mellon University
* Created for 4.2 BSD.
