how to bogotune?

[Trevor Smith]

Man, bogotune is very difficult to figure out. The man page is confusing since 
it does not clearly state what it means by "wordlist" and "message files". 
After numerous readings I think I have figured out what it wants: I'm 
assuming that the "wordlist" is just my wordlist.db that I've built over 
months of using bogofilter and that the "message files" are some group of 
emails that I have separated into spam and nonspam categories. Is this close 
to correct?

Next question:

If I have already trained bogofilter with the messages in question, can 
bogotune work on them? Or does that screw it up?

Final question:

The man page appears to say it wants 500+ messages of spam/ham each, with 
2000+ ham/spam each in the wordlist. I certainly have more than 2000 each in 
my wordlist, and I fed it ~1000 each for messages but it complained about 
"low number / uniformity" of messages and produced no useful results (that I 
can tell). 

My guess is that the messages I feed in must NOT be already trained, or else 
they're all going to read 1.0000 and 0.0000 (and that would make sense). Is 
this correct?
