- * Revision 1.46 1998-01-30 15:24:57 adam
+ * Revision 1.54 1999-04-16 14:45:55 adam
+ * Added interface for tcpd wrapper for access control.
+ *
+ * Revision 1.53 1999/02/02 13:57:39 adam
+ * Uses preprocessor define WIN32 instead of WINDOWS to build code
+ * for Microsoft WIN32.
+ *
+ * Revision 1.52 1998/08/21 14:13:34 adam
+ * Added GNU Configure script to build Makefiles.
+ *
+ * Revision 1.51 1998/07/07 15:51:03 adam
+ * Changed server so that it stops if bind fails - "address already in
+ * use" typically causes this.
+ *
+ * Revision 1.50 1998/06/22 11:32:39 adam
+ * Added 'conditional cs_listen' feature.
+ *
+ * Revision 1.49 1998/02/27 14:04:55 adam
+ * Fixed bug in statserv_remove.
+ *
+ * Revision 1.48 1998/02/11 11:53:36 adam
+ * Changed code so that it compiles as C++.
+ *
+ * Revision 1.47 1998/02/10 10:28:57 adam
+ * Added app_name, service_dependencies, service_display_name and
+ * options_func. options_func allows us to specify a different function
+ * to interogate the command line arguments. The other members allow us
+ * to pass the full service details accross to the service manager (CW).
+ *
+ *
+ * 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.
