+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)
