Hello.  Here's an attempt at modifying the Tcl "socket" command to
allow it to use unix-domain sockets as well as network sockets.

The modification involved adding "-local" to the socket command options.

contents
--------
Readme		- this file.
Tcl7.5-diffs	- patches to tcl7.5
eg-client.t	- a simple example of client-mode socket usage.
eg-server.t	- a simple example of server-mode socket usage.
example		- sample tcl and expectk scripts which make
		  use of the modified socket command.
shar-file	- this directory packed for easy shipping.

These patches seem to work under bsdi-3.1.
The bifftk script is in daily use on my workstation.

Hope this proves useful.

Paul Kern.
