Question (Q): What is sendxmpp? Answer (A): sendxmpp is a perl-script to send xmpp (jabber), similar to what mail does for mail. Sendxmpp was written by Dirk-Jan C. Binnema, and is available under the terms of the GNU GPLv2. The hard work is done by Ryan Eatmon's Net::XMPP-modules, and you need to have them installed for Sendxmpp to work. Obviously, to use sendxmpp , you need a jabber account; they are freely available at jabber.org, but you can also run your own server. The good news is, instant messaging between the Google Talk servers and its clients uses an open protocol, XMPP, allowing users of other XMPP/Jabber clients to communicate with Google Talk users.
