What is brew?
Brew or Homebrew is a package manager. Similar to Gentoo's Emerge, or Ubuntu's APT.
What does it do?
Homebrew installs the stuff you need that Apple didn’t. Installs packages to their own directory and then symlinks their files into /usr/local.
Terminal and type:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Updating package list
Packages change all the time. To make sure the list of packages and their versions is updated run this:
To search for a specific package type:
brew search STRING
brew install PACKAGE_NAME
brew remove PACKAGE_NAME
