* wserv.c - little program to be a pipe between a screen or

* Written by Troy Rollo, Copyright 1992 Troy Rollo
* Finished by Matthew Green, Copyright 1993 Matthew Green
* Support for 4.4BSD by Jeremy Nelson, Copyright 1997 EPIC Software Labs

* Works by opening up the unix domain socket that ircII bind's
