Back up and replay your apps with a Brewfile

Reinstall your whole environment with one command on a new Mac.

1. Export what is installed:

   brew bundle dump --file=~/Brewfile

   Copy
2. Review the file and remove what you no longer need.
3. On another Mac (with Homebrew installed):

   brew bundle --file=~/Brewfile

   Copy
4. Version the Brewfile in a Git repository to get your tools back in minutes.
