=head1 NAME

sa-learn - Munin plugin to monitor spamassasin bayes database size

=head1 APPLICABLE SYSTEMS

Any server running spamassassin

=head1 CONFIGURATION

This plugin assumes your Spamassassin database is in /var/lib/MailScanner.
If it's elsewhere (or you want to use a different database) you will need
a configuration such as:

   [sa-learn]
      env.BayesDir /path/to/bayes/directory/
      user mail

(where 'user mail' refers to a user that can read the database).
