=head1 NAME

Mail::SpamAssassin::Bayes - support for learning classifiers

=head1 DESCRIPTION

This is the general class used to train a learning classifier with new samples
of spam and ham mail, and classify based on prior training.

Prior to version 3.3.0, the default Bayes implementation was here; if you're
looking for information on that, it has moved to
C<Mail::SpamAssassin::Plugin::Bayes>.
