Probably, but is it in C and does it have a compatible license?

The bigger picture here is that our track record with use of external
libraries is just terrible: we've outlived the original maintainers'
interest multiple times. (That's how we got to the current situation
with the regex code, for example.) So I'd want to see a pretty darn
vibrant-looking upstream community for any new dependency we adopt.
