+     "The MediaWiki Parser From Hell is a python library package that provides
+a parser for MediaWiki.
+
+It exposes parses as normal string objects with additional methods giving
+access to the special Wikicode features it contains (hyperlinks, tags,
+templates…).  The parser doesn't interpolate strings at all, it remains at a
+purely formal level.
