New version up

[Mark S. Miller]

I integrated in everyone's suggestions (Thanks, MarcS, Terry, Chip, Kevin), 
and split level 3 into levels 3 and 4.  Enjoy, and fire away!


-----------------------------------------------------------
Due to a bug (possibly at my ISP, but probably in Eudora 4.2.0.58), on 9/15
I lost 18 email messages.  If it's possible for you to check whether you
sent me something on that date, resending it would be great.  Otherwise,
please excuse my non-responsiveness to email you may have sent around that
time.  Sorry for the inconvenience, and thanks.

         Cheers,
