   \ This relies on inetd or xinetd:
   
   \ To run the server on port 4444, do the following:
   
   \ Add the following line to /etc/services:
   \ gforth          4444/tcp
   
   \ If you use inetd, add the following line to /etc/inetd.conf:
   \ gforth stream tcp nowait.10000   wwwrun   /usr/users/bernd/bin/httpd
   
   \ If you use xinetd, create the folliwing service in /etc/xinetd.d:
   \ service gforth
   \ {
   \         socket_type     = stream
   \         protocol        = tcp
   \         wait            = no
   \         user            = wwwrun
   \         server          = /home/bernd/bin/httpd
   \ }
   
   \ If you want port 80, replace the service "gforth" with "http"
