Subject: * Rewritten rst plugin by madduck is a python program that
 communicates with   ikiwiki via XML RPC. This should be much faster than the
 old plugin that   had to fork python for every rst page render. Note that if
 you use   the rst plugin, you now need to have the RPC::XML perl module
 installed.
