Chat-O-Matic is a multi-protocol chat program based on Caya.
It can use protocols through native add-ons as well as through libpurple, the library used by Pidgin.
Protocols natively supported include IRC and XMPP.
Protocols generally supported through libpurple include GroupWise, Zephyr, and others through plugins.
You can find the user documentation here.
You can make Chat-O-Matic and its protocols with:
$ make
Or one-by-one:
$ make libs; make app; make protocols
Chat-O-Matic itself requires the expat_devel package, the XMPP protocol requires
gloox_devel, and the libpurple add-on requires libpurple_devel and
glib2_devel.
Protocol add-ons can be installed in any add-ons directory under chat-o-matic
(i.e., ~/config/non-packaged/add-ons/chat-o-matic/) or in the binary's CWD
(./chat-o-matic/).
libpurple plugins can be installed to any lib directory under purple-2
(i.e., ~/config/non-packaged/lib/purple-2/).
