How to use Latexdiff to mark changes to Tex documents.

Latexdiff is a tool for highlighting changes between two latex documents. So, I remind myself how to use it.

1. install Perl click
2. download latexdiff and unzip it into the Perl > bin folder
3. Optional: installing the latexdiff package in MiKTek appears to work as well.

How to use it:

1. cmd
2. cd to file folder
3. latexdiff oldfile.tex newfile.tex > diff.tex

Enjoy!
