good Spamassassin Summary report

I have searched far and wide for a good Spamassassin report using
numerous keywords in Google searches, but I can't find the one that fits
my needs. I am looking for a script that can be run via cron job on a
daily basis. I would pass the script the location of the mail log. The
output will show me for each rule, how many times that rule passed the
test. It will only show me the rules where the count is more than 0. For
example:

ALL_TRUSTED 287
BAYES_00   67
BAYES_10   43
BAYES_20   23
...
RCVD_IN_PBL   25


If you have found something similar to this, good. If you have created
your own script to do this, better. If Spamassassin has this script
created already and I missed it, even better.

Thanks in advance,
