And of course, I forget to tell you all where the solution is...  :P

Written by me:
http://tor.dhs.org/%7Ebwinton/python/chemweight.py              # My program

Writtne by John:
http://tor.dhs.org/%7Ebwinton/python/generic.py                 # The framework
http://tor.dhs.org/%7Ebwinton/python/framework-0.3/doc/faq.html # A FAQ

Sorry about that...
Blake.

P.S. John, if you're reading this, I couldn't find a "Token" class in
     generic.py.  Is it in an example file, or should there be a stub
     in generic.py?  The docs seem to suggest the latter.
