I use python to parse the files as well, but would prefer the
object-oriented approach I've seen in the owpython implementation. From
what I can tell, using the python would require nothing but the source, and
possibly an install using python-setuptools if one wanted to invoke it from
anywhere. I would be happy with the source that I could drop into a
directory and call the class instantiation objects after importing locally.
Parsing text is annoying, error-handling even worse. If someone has taken
care of these thankless jobs ahead of me, I have no desire to reinvent the
wheel.
