This is a script based approach to version control for TeX documents. It works more reliably than do keyword-substitution-based approaches, since it tracks more than just .tex files; it can work on all files in a working copy.

The vc bundle macros work with LaTeX and plain TeX. Currently, Bazaar-, Git- and Subversion-based repositories are supported; scripts are provided for use with both Unix and Windows.
