description	     determine and mark up significant differences between latex files
long_description latexdiff is a Perl script, which compares two latex files \
                 and marks up significant differences between them (i.e. a \
                 diff for latex files). Various options are available for \
                 visual markup using standard latex packages such as \
                 color.sty. Changes not directly affecting visible text, for \
                 example in formatting commands, are still marked in the latex \
                 source.
