Just thought remembered today that all of you latex users (like me) would like to know about latexdiff (http://www.ctan.org/tex-archive/support/latexdiff/). This perl script compares two versions of a latex document and generates another latex file which, when compiled, has the differences highlighted. Although latex sometimes complains a little when compiling the diff file, its works reasonably well. I have used it for some time to help my co-authors visualize what changed in a paper.
