What is a good way to show changes between two versions

I done a bunch of updates in an article. I have a copy of an old revision of the paper. Now I would like to generate a PDF/DVI illustrating the updates I've done.

Is there any tool or package that would help me with this?

(The article is under SVN version control, if that helps.)

    DiffPDF can show you difference between two PDFs, but it won't generate new PDF showing them. Just a not really helpful side note, in case you don't know this tool. – przemoc Jun 22 '11 at 12:49

There is a useful Perl script to display differences between two LaTeX files: it creates a new LaTeX file that, when compiled, highlights changes with different colors. It is called latexdiff and also works with version control files.
