Quick script to generate a latexdiff of two revisions of a latex document in a repo.

make_latexdiff.sh

#!/bin/bash

# This script generates a diff of two different git revisions of a
# tex file.  Note that a few things should be true:
# -The two revisions should share the same latex style.  (article,llncs,etc.)
# -The main file of each should be called main.tex
# -Everything must be in a git repository

if [ "$#" -ne 2 ]
then
    echo "Usage: $0 <git-revision1> <git-revision2>"
    exit -1
fi
