One of the core parts of Coccinella is JabberLib, a BSD licensed library written in Tcl. Although the library is included in Coccinella, you also can download JabberLib as a separate download. The development version of the library is available in the Coccinella development repository. JabberLib hides all XML used by the Jabber/XMPP protocols. Additionally, a few test files are included to get you started, and although no documentation is available, there is a brief summary of commands in the prefix header of each source file.

Also a patched TclXML package, needed for XML parsing in Tcl, is included.
