I guess I'm a bit of a newbie to extensions; looking for ParserHook on
wikimedia.org/wiki brought up a lot of results, but I'm not sure which
one will do what I need, and sorting through them all seems a bit
foolish. What exactly might such an extension be called? I've already
seen the articles for extending wikitext, but it doesn't seem to contain
anything specific enough/pertaining to my situation.
