Uses the mozilla IDL parser to write Restructured Text files for interfaces. It's pretty rough and I don't really remember how to invoke it.

	import os.path
	import re
	import sys
	from xpidl import xpidl


	def _get_xpidl_interface_docs(i):
	# This function is horrible. We probably need full docblock parsing
	# support to extract @param.
