- * Revision 1.6 1995/02/17 14:41:14 quinn
+ * Revision 1.19 1995/03/02 09:32:11 adam
+ * New presentation formats. f0=full, f1=brief, f2=mid
+ *
+ * Revision 1.18 1995/03/01 14:32:26 adam
+ * Better diagnostics. Default is, that only one database selected when
+ * several are known.
+ *
+ * Revision 1.17 1995/02/28 13:16:26 adam
+ * Configurable From: added.
+ *
+ * Revision 1.16 1995/02/23 10:08:20 adam
+ * Added logging of all user commands.
+ *
+ * Revision 1.15 1995/02/23 08:32:17 adam
+ * Changed header.
+ *
+ * Revision 1.13 1995/02/22 16:54:42 adam
+ * Qualifiers of LOC target updated. More logging messages.
+ *
+ * Revision 1.12 1995/02/22 15:51:51 adam
+ * Bug fix: swap of parameter number and offset in function present.
+ *
+ * Revision 1.11 1995/02/22 15:22:33 adam
+ * Much more checking of run-time state. Show command never retrieves
+ * more records than indicated by the previous search request. Help
+ * command available. The maximum number of records retrieved can be
+ * controlled now.
+ *
+ * Revision 1.10 1995/02/22 08:51:35 adam
+ * Output function can be customized in fml, which is used to print
+ * the reply to reply_fd.
+ *
+ * Revision 1.9 1995/02/21 17:46:21 adam
+ * Minor changes.
+ *
+ * Revision 1.8 1995/02/21 12:12:00 adam
+ * Diagnostic record with error info. observed.
+ *
+ * Revision 1.7 1995/02/20 21:16:20 adam
+ * FML support. Bug fixes. Profile for drewdb.
+ *
+ * Revision 1.6 1995/02/17 14:41:14 quinn
