Generally, even a recursive descent parser will be overkill. It's
pretty easy to do simple string manipulation to get the info you want;
maybe that means restricting the syntax some, but for a personal-use
script, that's usually no big cost. The example I gave requires that
the indentation be correct, and on this mailing list, I think people
agree that that's not a deal-breaker :)
