-# 1999/09/20 RM Creation
-#
-# 1999/09/20 TP Changed script to use strict, more secure by
-# specifying $ENV variables. The bind command is
-# still insecure through. Did most of my work
-# with perl -wT and 'use strict'
-#
-# test using check_ircd.pl (irc-2.mit.edu|irc.erols.com|irc.core.com)
-# 2002/05/02 SG Fixed for Embedded Perl
