entry matched, which provides a mechanism for expiring the
score entries. It this element is not present, the score
entry is permanent. The date is represented by the number of

4. The \"type element\". This element specifies what function should

For the Date header we have three kinda silly match types: `before',
`at' and `after'. I can't really imagine this ever being useful, but,
like, it would feel kinda silly not to provide this function. Just in
case. You never know. Better safe than sorry. Once burnt, twice
shy. Don't judge a book by its cover. Never not have sex on a first
date. (I have been told that at least one person, and I quote,
\"found this function indispensable\", however.)
A more useful match type is `regexp'. With it, you can match the date
string using a regular expression. The date is normalized to ISO8601
compact format first---`YYYYMMDDTHHMMSS'. If you want to match all
articles that have been posted on April 1st in every year, you could
use `....0401.........' as a match string, for instance. (Note that
the date is kept in its original time zone, so this will match
articles that were posted when it was April 1st where the article was
posted from. Time zones are such wholesome fun for the whole family,
eh?")))

an article with a `Message-ID' X, then you add a `thread' match. This
will add a new `thread' match for each article that has X in its
`References' header. (These new `thread' matches will use the
`Message-ID's of these matching articles.) This will ensure that you
can raise/lower the score of an entire thread, even though some
articles in the thread may not have complete `References' headers.
Note that using this may lead to undeterministic scores of the
articles in the thread.
