I've been thinking about something like this myself, and I believe I have an
idea which may work. The key is to make "version.txt" a plain file (i.e. not
versioned in the repository), and just have it updated/created by the hook
system for every commit. In other words, use post_commit rather than
pre_commit. I'd have to assume that your repository and web server wc are
located on the same machine (for ease of scripting) or else you have to use ssh
or something to create the file on a remote filesystem.

The only difficulty here is that you must create some other method of generating
this file when checking out a new wc, but that is trivial once you have the
above script.
