Don't commit focused tests. Use this as a pre-commit hook and the commit won't succeed if you have staged changes that contain `fdescribe`, `fcontext`, `fit`, `fspecify` or `fexample`. Copy this file as `pre-commit` into the `.git/hooks` folder of your repository (create it if neccessary) and chmod +x the file.

# This pre-commit hook looks for `fdescribe`, `fcontext`, `fit`, `fspecify` and `fexample` in the
# staged files and exits with an error code of 1 if there are such changes.
