Using homebrew and cask package managers in OSX

Homebrew is a package management system for OSX. It installs packages in its own cellar directory and symblinkes to /usr/local.

Homebrew terminology: Formula is the package definition, keg is formula installation prefix, cellar is where all kegs are installed, tap is optional formula repositories, bottle is pre-built binary keg that can be unpacked.
