hey,

I read "make the git version number part of the document" within the
TODO-file, so I updated the project to use gitinfo for adding metadata
to the footer of the (pdf)-output files.

I am not quite THE git-crack, and this is just one way to do it.
Another way would possibly be via the Makefile, dunno.

If you add the script below to your .git/hooks/ as post-commit,
post-checkout and post-merge, it will do the trick.

hth, Ulrich
