The Jabber::RPC::HTTPgate is an experimental package that
allows you to bridge traditional (HTTP-based) XML-RPC calls
and Jabber-RPC calls.
With the Jabber::RPC::HTTPgate module you can set up a
gateway between HTTP-based and Jabber-based XML-RPC, so
a Jabber-RPC requester can make calls to an HTTP-based
responder, and vice versa.
See the module documentation for more details. There are
lots of examples in the distribution.
