A handy script to sanitize a latex project for an arXiv submission (Mac)

prepForArxiv.sh

# This script sanitizes a latex project for an arXiv submission.
# Specifically, it "sanitizes" the project by removing any files that are not used in compilation.
# 
# Usage:
#   cd latex_folder_root
#   ./prepForArxiv.sh
#   (generates a zip archive in /tmp/archive.zip)
# 
# It is not exhaustive, but it is pretty good and should work for most cases.
# Also, it does not remove comments within the latex source.
# It was written to be run on mac with gsed = GNU sed, but with grep = Mac/BSD grep, but should
#   require minimal changes to work with Linux.
