Rabbiter is an ejabberd module providing a bot - rabbiter@rabbiter.DOMAIN, by default - which provides a microblogging 
service when you add it to your roster.

To compile:

* get ejabberd sources [1]
* get, and install, RabbitMQ - http://www.rabbitmq.com/download - make sure you get the latest repository sources! [2]
** you'll need "rabbitmq-server":http://hg.rabbitmq.com/rabbitmq-server/archive/tip.zip and 
"rabbitmq-codegen":http://hg.rabbitmq.com/rabbitmq-codegen/archive/tip.zip
** unzip them
** rename the "rabbitmq-codegen-(lots of hex digits)" directory to "rabbitmq-codegen", and similarly for rabbitmq-server

** in the rabbitmq-server directory, type "make"
** symlink the rabbitmq-server so it is available at your lib/erlang directory [3]
* get rabbiter sources
* symlink mod_rabbiter.erl into ejabberd/src/.
* build ejabberd
* add a mod_rabbiter stanza to ejabberd.cfg [4].
* start ejabberd

If you configured ejabberd to serve DOMAIN, and you didn't supply any special domain for the rabbiter module, you can 
now add rabbiter@rabbiter.DOMAIN to your roster. It ought to send you a welcome message.

If you want rabbiter@someother.domain, change the ejabberd.cfg stanza for rabbiter to  {mod_rabbiter, [{host, 
"someother.domain"}]}.
