Does anyone have any gentle nudges to information explaining what 
hapaxes are in a spambayes context?  I _think_ I've canvased the 
website, some of the docs that come with the install (enough to get it 
running under Linux), etc., but I don't recall seeing anything about 
them.  I'm not afraid to Use the Source, Luke (but not while I'm here at 
work ;), so just a pointer to a file name would probably be enough (if 
there's a hapax.py I'm gonna feel silly - I'll check when I get home ;).

Thanks!
