* $Log: yaz-ir-assoc.cpp,v $
- * Revision 1.4 1999-03-23 14:17:57 adam
- * More work on timeout handling. Work on yaz-client.
- *
- * Revision 1.3 1999/02/02 14:01:19 adam
- * First WIN32 port of YAZ++.
- *
- * Revision 1.2 1999/01/28 13:08:43 adam
- * Yaz_PDU_Assoc better encapsulated. Memory leak fix in
- * yaz-socket-manager.cc.
- *
- * Revision 1.1.1.1 1999/01/28 09:41:07 adam
- * First implementation of YAZ++.
+ * Revision 1.5 1999-04-09 11:46:57 adam
