I'm open to exploring that path. I just took a serious look at
wflinfo.c, and it's needless complex for the little job that it does. If
you could port it to Python, greatly reducing and simplifying the code,
I'd like to see that.

I've never used Python's C interface, so I look forward to learning
about it from your patches.
