Yes, what if we build the version from the VERSION file (+ last git commit short hash + BUILD_EPOCH, only when building from git)?

This would avoid having to calculate the distance to the tag, etc, that autorevision currently does.

The BUILD_EPOCH would still only be set at configure time, so you'd need to do "waf configure build" after each edit, instead of just "waf build".

Does that simply things enough, while still remaining usable for devs?
