David,
I'll probably be trying Robinson-Fisher when I upgrade.

However I have some questions that don't seem to be answered in any of the 
files in 0.10.0:

1. does bogofilter -u handle the unknown case (i.e. does nothing)?

2. is there a exit/return code for unknown so I can handle it in procmail?

3. is there a tag with -p that says "Unknown" so I can use it in the MUA?

4. are the default cutoffs, ROBS, ROBX, etc set appropriately if I build 
with Robinson-Fisher set as the default? i.e. can just compile and start 
using it, or do I need to figure out what values to use?

5. is "--enable-robinson-fisher" the configure command to set 
robinson-fisher as the default?

Thanks,
Barry
