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
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

$ # What version did I just download?
$ cat libfabric.spec | grep '^Source0'
Source0:        https://github.com/ofiwg/%{name}/releases/download/v%{version}/%{name}-%{version}.tar.bz2

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

$ nix run --impure --expr 'let pkgs = import ./. {}; in pkgs.python3.withPackages (pp: [ pp.specfile ])'

>>> import specfile
