# cmd_resolve.tcl
# written by Jeff Fisher (guppy@eggheads.org)
#
# This script adds the commands '.resolve' and '.dns' which can be used to
# lookup hostnames or ip addresses in the partyline without causing the bot
# to block while doing so thanks to the dns module.
#
# updates
# -------
# 15Apr2003: fixed a logging bug and stop using regexp incorrectly
# 05Nov2000: fixed a nasty security hole, .resolve [die] <grin>
# 04Nov2000: first version
#
