contribute to homebrew

this tip assumes you are using hub instead of git (via alias hub='git')

• open taps dir cd /usr/local/Library/Taps
• switch to desired tap dir cd <tapname>
• git fork to create a fork
• git checkout -b <feature-name> to create a feature branch
• brew edit <formula> or brew cask edit <formula> (or create instead of edit)
• git commit your changes and git push <username> them to your fork
• git pull-request will create a pull-request from your current branch to origin
• git checkout master to return things to normal
