All *nix devs seethe with rage when DOS line-endings (CRLF) end up in your beautiful source code, right? If you use Git for your version control you’re in luck, use this local pre-commit hook to kick those CRLFs to the kerb before they can even make it into your local commit.
Install by copying the pre-commit file to the .git/hooks directory of your checkout. Ask your Windows using colleagues nicely to do the same.
