This revision now requires changes to proceed.

If I'm remembering correctly from when I set this up, this isn't just about detecting which version control system you're using; it's about finding a file //that will change on every commit.// Otherwise, the generated Version.cpp won't be rebuilt after you update.

If you don't want to go looking for a better choice for this that would handle submodules, a stopgap answer would be to add a second entry that just looks for `.git` in addition to the one looking for `HEAD`.
