Net::XMPP is a convenient tool to use for any perl script that would
like to utilize the XMPP 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::XMPP is a wrapper around the rest of the official
Net::XMPP::xxxxxx packages.
