Subject: Use 'git describe' to get current version number in checkVersions()
X-Git-Url: https://git.ralfj.de/mass-build.git/commitdiff_plain/1c97a041534e9aacaba12939729eb1ab3ea3d798?ds=inline;hp=7e9392d1b724df00869c018b3ed9aabc6d2dc5a4

Use 'git describe' to get current version number in checkVersions()

The old method could not deal well with multiple tags for the same commit
