# This is a MacPerl script which attempts to impliment autorun functionality
# for MacOS.  It's a bit of a bastardisation of MacPerl and "standard" unix
# style perl.  I won't claim that it's pretty.  Parts of it come from the
# Autorun perl script for unix that is distributed with CircleMUD and it is
# therefore subject to the following.
