44 * Revision 1.11 1996/05/23 15:53:11 adam
45 * Bug fix: egw_enc failed on 8-bit chars.
46 * New command: egw_parms.
48 * Revision 1.10 1996/05/21 14:53:04 adam
49 * Tcl command wform extented; options -raw and -exists added.
51 * Revision 1.9 1996/03/14 11:48:39 adam
52 * New function egw_prog that returns name of shell.
54 * Revision 1.8 1996/02/12 10:09:25 adam
55 * New parameter to wproto_init: directory root for the FIFOs (instead
56 * of using preprocessor defines FIFODIR/FIFOROOT).
58 * Revision 1.7 1996/01/24 08:26:55 adam
59 * All tcl commands prefixed with egw_ (except the html command).
61 * Revision 1.6 1996/01/12 13:08:07 adam
62 * CGI script passes name of lock file to the shell. The server will not close
63 * the response FIFO until this file becomes unlocked. This method handles
64 * cancel operations much better.
66 * Revision 1.5 1996/01/12 10:05:21 adam
67 * If script name ends with ';' HTTP/GET/Expires will be defined.
68 * The cgi interface only reads final handshake if response from
69 * server (shell) was zero-terminated [If it isn't it probably died].
71 * Revision 1.4 1995/11/06 10:51:18 adam
72 * End of response marker in response from wsh/wproto to wcgi.
73 * Shells are respawned when necessary.
75 * Revision 1.3 1995/10/27 15:12:11 adam
76 * IrTcl incorporated in the gateway.
77 * Better separation of script types.
78 * Z39.50 gateway scripts entered.
80 * Revision 1.2 1995/10/23 16:55:41 adam
81 * A lot of changes - really.
83 * Revision 1.1 1995/10/20 11:49:27 adam
84 * First version of www gateway.
