# ircd-shortcut.pl
# This script generates ircd command shortcuts for use with 
# ratbox-services.  These are notably safer to use than users simply 
# messaging the service nicknames, as they cannot be intercepted 
# by other users when services is split.
#
# This file will output to m_rsshortcut.c, which can then be compiled
# as an ircd module and installed.  The module generated is for use
# with ircd-ratbox-2.1.x.
