# Usage:
# as your user /remote on (uncomment the $remote = 1 line below if you want it
# on by default)
# /msg user remote login password
# then /msg user remote command
# it will execute the command on the same server...
# so you can do mode #channel +o whoever
# but it will allow any command, yes it's dangerous if someone knows the
# password they can access just about anything your user account can....
# put a crypted password here
