+ * More work on scan. The search.egw script takes care of cached
+ * query page (doesn't always increment nextSetNo). To make new search set
+ * either 'New query' must be selected or the query page must be reloaded.
+ * The msearch script doesn't do this yet, however.
+ *
+ * Revision 1.9 1995/11/14 16:31:36 adam
+ * Temporary remove of ccl entry.
+ *
+ * Revision 1.8 1995/11/13 15:41:45 adam
+ * Arrow gifs.
+ * Gateway uses record element set names B(rief) and F(ull).
+ * Bug fix. Didn't save idAuthentication correctly.
+ *
+ * Revision 1.7 1995/11/10 14:47:32 adam
+ * Plus (+) characters automatically converted to space in forms.
+ * Work on search in multiple targets. Doesn't work well - yet.
+ * Presentation formats enhanced.
+ *
+ * Revision 1.6 1995/11/06 10:51:17 adam
+ * End of response marker in response from wsh/wproto to wcgi.
+ * Shells are respawned when necessary.
+ *
+ * Revision 1.5 1995/11/02 16:35:37 adam
+ * Bug fixes and select on FIFOs in wcgi - doesn't really work!
+ *
+ * Revision 1.4 1995/10/31 16:56:25 adam
+ * Record presentation.
+ *
+ * Revision 1.3 1995/10/27 15:12:10 adam
