Git pre-commit hook for large files
This hook warns you before you accidentally commit large files to git. It's very hard to reverse such an accidental commit, so it's better to prevent it in advance.
Since you will likely want this script to run in all your git repos, a script is attached to add this hook to all git repos you create / clone in the future.
Of course, you can just download it directly to the hooks in an existing git repo.
