# to one of your contacts. You can pass the message as the first command
# line argument to the script. The default message is "Poke!". Change the
# NAME, PROTOCOL and TO variables at the beginning of the script to your
# liking. Make sure the account is enabled in your Pidgin or the script
# will fail.
