Good.  By the Scheme bindings do you mean the hooks for the report-
generating guile code?

Yes, in principle.

I hadn't known about the python bindings.  First, it would make sense for 
me to try to use the python bindings to see if I can do what I need, 
writing a kind of a diary of what I discover I need to know and producing 
bits of preliminary documentation as I go.  How does collaboration work 
with documentation?  Is it a wiki?  or svn access?  or something else?
