packaging for Gentoo Linux

[dlan17]

hello, I'm trying to pack this great tool for Gentoo Linux, while face a build err.
It fail to find version info from PKG-INFO or METADATA (which both files not found)

I'm not familiar with Gentoo packaging, however, the error message seems clear. I suspect you're using the tarballs from GitHub when what you actually want is an sdist tarball. You can build one of those with python setup.py build_sdist.
