This is a whole lot better than nothing, but it's a shame it forks python
every page. Anyone want to get [this](http://search.cpan.org/~nodine/Text-Restructured-0.003016/) into Debian and use it instead?

# Very simple reStructuredText processor.
#
# This plugin calls python and requires python-docutils to transform the text
# into html.
#
# It's main problem is that it does not support ikiwiki's WikiLinks nor
# Preprocessor Directives (in fact the same problem applies to the current
# Wikitext processor, although in that case the output looks less worse ;)
#
# Probably Wikilinks and Preprocessor Directives should support a list of
# extensions to process (i.e. the linkify function could be transformed into
# reStructuredText instead of HTML using a hook on rst.py instead of the
# current linkify function)
