NAME
Mail::SpamAssassin::Bayes - support for learning classifiers
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 "Mail::SpamAssassin::Plugin::Bayes".
