FAQ update

[David Relson]

Greetings,

It's been a long time since the FAQ has been changed.  Here are a few 
things I'm going to add:

Q: I'm running bogofilter from inside a program and getting return codes 
like 0 and 256.  Why am I not getting 0 and 1 like the bogofilter docs say?

A: Likely the return codes are being reformatted by waitpid(2).  Use 
WEXITSTATUS(status) in sys/wait.h, or comparable macro, to get the correct 
value.

Q: How do I find the spam and ham counts for a token?

A: Use bogoutil's '-w' option to display info about a token (word).  For 
example, "bogoutil -d $BOGOFILTER_DIR example.com" gives the good and bad 
counts for "example.com".

Q: How do I tell how many messages are in my wordlists?

A: Use bogoutil's '-w' option to display the value of special token 
.MSG_COUNT, i.e. run command "bogoutil -w $BOGOFILTER_DIR .MSG_COUNT" to 
see the counts for the spam and ham wordlists.

Q: How do I tell how many tokens are in my wordlists?

A: Pipe the output of bogoutil's dump command to command "wc", i.e. use 
"bogoutil -d $BOGOFILTER_DIR/spamlist.db | wc -l " to display the count for 
the spamlist and use "bogoutil -d $BOGOFILTER_DIR/goodlist.db | wc -l " to 
display the count for the goodlist.

What other questions and answers have y'all asked that should be 
included?  Please post them to the mailing list so we can all contribute.

Thanks.

David
