- * Revision 1.8 1995/11/06 17:44:23 adam
+ * Revision 1.23 1998/03/26 11:29:02 franck
+ * Fixed some bugs with escape sequences.
+ *
+ * Revision 1.22 1997/12/15 15:05:03 adam
+ * Enhanced the code that deals with FORM variables.
+ *
+ * Revision 1.21 1997/02/10 10:15:40 adam
+ * Bug fix: egw_source <file> <var> didn't work properly.
+ *
+ * Revision 1.20 1997/01/31 11:16:01 adam
+ * Enhanced the egw_source command. An optional parameter specifies the
+ * name of a variable in which the HTML output is stored.
+ *
+ * Revision 1.19 1997/01/27 11:27:17 adam
+ * Implemented a new command, egw_clear, to clear http output cache.
+ * Changed prototype for function wo_clear.
+ *
+ * Revision 1.18 1997/01/24 13:13:13 adam
+ * Implemnted egw_source and added a "raw" option to the URL.
+ * Fixed a bug in the buffering system of wproto; the macro wo_putc could
+ * override memory if it was the first HTML generating function called.
+ *
+ * Revision 1.17 1996/05/31 08:02:56 adam
+ * Bug fix: egw_enc encoded '/' - it shouldn't.
+ *
+ * Revision 1.16 1996/05/23 15:53:12 adam
+ * Bug fix: egw_enc failed on 8-bit chars.
+ * New command: egw_parms.
+ *
+ * Revision 1.15 1996/05/22 16:50:27 adam
+ * Bug fix.
+ *
+ * Revision 1.14 1996/05/21 14:53:04 adam
+ * Tcl command wform extented; options -raw and -exists added.
+ *
+ * Revision 1.13 1996/03/14 11:48:40 adam
+ * New function egw_prog that returns name of shell.
+ *
+ * Revision 1.12 1996/03/07 12:45:34 adam
+ * New Tcl calls egw_enc/egw_dec to encode/decode binary URL info.
+ *
+ * Revision 1.11 1996/01/24 08:26:56 adam
+ * All tcl commands prefixed with egw_ (except the html command).
+ *
+ * Revision 1.10 1995/11/08 16:14:35 adam
+ * Many improvements and bug fixes.
+ * First version that ran on dtbsun.
+ *
+ * Revision 1.9 1995/11/07 14:57:00 adam
+ * Work on search in multiple targets.
+ * New wtcl command: wlog.
+ * Optional timeout parameter to zwait.
+ *
+ * Revision 1.8 1995/11/06 17:44:23 adam
* State reestablised when shell restarts. History of previous
