- * $Log$
- * Revision 1.10 1988-08-01 18:17:58 qjb
- * Almost finished version supporting new SMS protocol.
- * Kerberos problems.
- *
- * Revision 1.9 88/07/26 14:50:40 qjb
- * Added comments and did some cleaning up in preparation for rewrite.
- * This version will not run; the last version that will is 1.8.
- *
- * Revision 1.8 88/07/20 15:39:25 mar
- * find realm at runtime; don't use hard-coded one
- *
- * Revision 1.7 88/02/08 15:08:15 mar
- * Moved header file locations
- *
- * Revision 1.6 87/09/21 15:19:11 wesommer
- * Allow numbers, _, and . as legal characters in the username.
- *
- * Revision 1.5 87/09/10 22:18:32 wesommer
- * Clean up output format.
- *
- * Revision 1.4 87/09/04 23:33:19 wesommer
- * Deleted test scaffolding (second oops.)
- *
- * Revision 1.3 87/09/03 03:05:18 wesommer
- * Version used for userreg tests.
- *
- * Revision 1.2 87/08/22 18:39:45 wesommer
- * User registration server.
- *
- * Revision 1.1 87/07/31 15:48:13 wesommer
- * Initial revision
- *
+ * This program is a client of the Kerberos admin_server and a
+ * server for the userreg program. It is not a client of the
+ * Moira server as it is linked with libmoiraglue which bypasses
+ * the network protocol.
