If you use Subversion for tracking changes to your LaTeX files, you might want to check out (ha!) a LaTeX package called `svn-multi`. The Table of Revisions feature in `svn-multi` is really neat when you have a master file and you `\input` a lot of subfiles in the master file. Take a look at http://mirror.ctan.org/macros/latex/contrib/svn-multi/.
