Perl: Send a chat message to your gmail buddy using Jabber

Net::Jabber provides a Perl user with access to the Jabber Instant Messaging protocol. Net::Jabber is a convenient tool to use for any perl script that would like to utilize the Jabber Instant Messaging protocol. While not a client in and of itself, it provides all of the necessary back-end functions to make a CGI client or command-line perl client feasible and easy to use. Net::Jabber is a wrapper around the rest of the official Net::Jabber::xxxxxx packages.

Below a sample script to send a chat message to your gmail buddy.

#!/usr/bin/perl

# Program:  sendmessage.pl                          #
