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= 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. * ********************************************************************** */ /* PGMVERSION is defined separately in each program */ extern char scmversion[];
