To install GameServ, it takes  easy tasks:

1.) ./configure
2.) make
3.) cp gameserv.example.conf gameserv.conf
4.) pico gameserv.conf  (or use text editor of your choice)
5.) ./gameserv

Somewhere inbetween steps 4 and 5 you should setup your ircd to accept 
the connection from the gameserv server. This is accomplished by adding 
either C/N lines or a link {}; directive.
