Re: [cclib-devel] C bridge and changes to the progress updater

[Noel O'B. <bao...@gm...>]

I've never heard of calling a Python library from C++, but sounds very
interesting. Regarding the API change, that will need a cclib 2.0. I
have no particular objection to this if necessary but you should
probably check this into a branch while I get out this release. Unless
there's a way to support the existing behaviour while adding the new
one.
