Hook Into Post-Merge?

[Ben]

I need a version number stored in text file. I want to increment it whenever I update a branch on the server automatically. I need that version file alongside all the other files.

Is there anyway to do this? After brief research it seems I can do this with GIT hooks, but these are not available for use with bitbucket.

Why not have your build server do this? Otherwise - use the git commit sha... You can't really do it with Git since things are not unique.
