Easy way to convert POPFile database to Bogofilter?

(I resend this message because the first one I sent did not
show up in the 
Bogofilter list archives, possibly because my original note
was sent from 
an email list that was not subscribed.  My apologies if
you're seeing this 
twice.)

I'm looking for the easiest way possible I can convert a
longstanding 
POPFile Bayesian data collection to a Bogofilter system.

For now, I plan to convert the sqlite-based POPFile data via
a script that 
I create (probably in Python) to a Bogofilter format for a
Bogofilter, 
server-based import.

Thing is, I don't want to have to do this work from scratch,
and I'd prefer 
to reuse some mechanism (Bogofilter feature or third-party
script or 
something else?) that already exists to do this.  If nothing
exists, can 
anyone offer any specific pointers on how to do this (eg,
making sure I'm 
looking at the right Bogofilter-import-format specs--I can't
find any in a 
quick documentation search, I'm only getting a format spec
told to me by 
the admin of the bogofilter server)?  This work doesn't
appear to be that 
hard at first glance, but I don't want to presume too much.

Thanks for any help,
-Matt
