Subject: Use a static file for versioning
X-Git-Tag: v3.2.0~135
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3bd537e7120f6dd70dc0454a920ec327372856e0;p=thirdparty%2Fpatchwork.git

Use a static file for versioning

This means you don't have to install all dependencies simply to read the
version.
