- * 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
- *
- * $Log: supmsg.c,v $
- * Revision 1.2 1993/08/04 17:46:23 brezak
- * Changes from nate for gzip'ed sup
- *
- * Revision 1.1.1.1 1993/05/21 14:52:19 cgd
- * initial import of CMU's SUP to NetBSD
- *
- * Revision 2.4 92/09/09 22:05:17 mrt
- * Moved PFI definition under __STDC__ conditional since it
- * is already defined in libc.h in this case.
- * [92/09/01 mrt]
- *
- * Revision 2.3 92/08/11 12:08:12 mrt
- * Added copyright
- * [92/08/10 mrt]
- * Brad's changes: Delinted, Incorporated updated variable
- * argument list usage from old msgxfer.c
- * [92/07/24 mrt]
- *
- * Revision 2.2 89/08/23 15:02:56 gm0w
- * Created from separate message modules.
