Note: As git doesn't provide human readable (or better understandable) revision IDs by itself and we also don't intend to manually update the revision.h file or use funky ID generation tools, this workaround will do the trick for now. To find out your repositories revision ID use: git log --pretty=format:"" origin/HEAD | wc -l
