python3Packages.specfile: init at 0.32.6

[sielicki]

what is it?

This is a library from the packit project which provides a python interface for
parsing RPM spec files. It requires and uses pkgs.rpm/pkgs.python3Packages.rpm
under the hood for evaluation.

$ # grab a random spec from fedora rawhide
$ curl https://src.fedoraproject.org/rpms/libfabric/raw/rawhide/f/libfabric.spec -o libfabric.spec

$ cat libfabric.spec | grep '^Source0'

$ # argh, need to emulate the rpm macro rules to know what this expands to...
