#
# For those guys that still like to open ports
# and use non-rooted boxes
#
# This has been developed to join in the TocToc
# project code, now it's done and I'm distributing
# this separated
#
# This one i made without IO::Pty so it uses
# only standard modules... enjoy it
#
# tested on linux boxes.. probably will work fine on others
# any problem... #atrix@irc.brasnet.org
