 * 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
 *
 * 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.
