Nice to hear that you find it useful. Thank you very much for sharing
your results.

Yes, that's a good fix for Windows. Actually, I copied this code
from Generic-Haskell, and simplified it because I only needed it for
Unix and did not have time to test it under Windows anyway.

For the next release, I will try to merge the full Generic-Haskell
library, which defines "environmentSeparators" and a few other
functions in several "OSSpecific.hs" files, one of which can,
depending on architecture, be included by lhs2TeX.

I agree on all that. I even think that there probably are several
projects that have done most of that already, and that it would just
be necessary to collect some source code and streamline the interface.
I like the Python interface, BTW. It seems simple and pragmatic
enough.

Thanks again.
