Compare revisions of latex files using latexdiff

Acquire latexdiff package (depends on OS)­. Also available on CTAN.

run:

$ latexdiff draft.tex revision.tex > diff.tex

Compile diff.tex using your favorite sequence.

In order to take into account for \input and \include,

use the --flatten option.

The includes will point to their respective directories.

NOTE: the diff can take a long time for large document, like a PhD thesis :D
