OK, found it.

Yeah... looks like perl code. ;-)

OK... as an exercise in understanding the code, I
made the main body into a function, factored
out 3 parts, and added doctests. Enjoy.

While I was at it, I think I fixed a bug: in
the case of "Not a valid URI Template", I think
your code gives an HTTP 200 and then prints
an HTTP 400 status message in the body.

You might add a clue about how to satisfy 'import tpg'
in template_parser.py; tpg isn't in apt nor the CheeseShop,
so I had to hunt for it a bit.

I made an hg clone of the SVN project with hgimportsvn first,
just for fun our out of habit or whatever...
