This looks reasonable, but in practice I think the use of this will be 
cumbersome -- expect some very long commandlines.

Looking forward, I think we should consider adding one or more hooks 
that allow arbitrary user code to be run during the conversion process 
-- perhaps arbitrary so long as it is Python code.

Certainly I've done this myself and I have read of others on the mailing 
list doing the same.

Is there a convenient mechanism for calling arbitrary Python modules 
named in the configuration?
