callback bayes_scan

[Jeroen Koekkoek]

Hi,

I dived a little deeper into SpamAssassin's code. In 
lib/Mail/SpamAssassin/Plugin/Bayes.pm a plugin is called. It concerns the 
following code:

----- code -----
  $self->{main}->call_plugins("bayes_scan", { toksref => $msgtokens,
                                              probsref => \%pw,
                                              score => $score,
                                              msgatime => $msgatime,
                                              significant_tokens => 
\@touch_tokens,
                                            });
----- /code -----

I can't figure out where this method resides, can anyone point me in the right 
direction? There seems to be no subroutine called bayes_scan in the entire 
codebase?

Thanks in advance.
