- * Revision 1.39 1997-09-09 10:10:19 adam
+ * Revision 1.46 1998-01-30 15:24:57 adam
+ * Fixed bug in inetd code. The server listened on tcp:@:9999 even
+ * though it was started in inetd mode.
+ *
+ * Revision 1.45 1998/01/29 13:30:23 adam
+ * Better event handle system for NT/Unix.
+ *
+ * Revision 1.44 1997/11/07 13:31:52 adam
+ * Added NT Service name part of statserv_options_block. Moved NT
+ * service utility to server library.
+ *
+ * Revision 1.43 1997/10/31 12:20:09 adam
+ * Improved memory debugging for xmalloc/nmem.c. References to NMEM
+ * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
+ * Bug fix: missing fclose in data1_read_espec1.
+ *
+ * Revision 1.42 1997/10/27 14:03:02 adam
+ * Added new member to statserver_options_block, pre_init, which
+ * specifies a callback to be invoked after command line parsing and
+ * before the server listens for the first time.
+ *
+ * Revision 1.41 1997/09/29 07:19:32 adam
+ * Server library uses nmem_init/nmem_exit. The log prefix no longer
+ * includes leading path on NT.
+ *
+ * Revision 1.40 1997/09/17 12:10:41 adam
+ * YAZ version 1.4.
+ *
+ * Revision 1.39 1997/09/09 10:10:19 adam
* Another MSV5.0 port. Changed projects to include proper
* library/include paths.
* Server starts server in test-mode when no options are given.
