Install HomeBrew package manager for Mac

Homebrew is the easiest and most flexible way to install the UNIX tools Apple didn't include with OS X. It provides a simpler alternative to MacPorts, installing under an isolated non-root prefix, symlinked to /usr/local

You do not need to use sudo when using Homebrew as software is installed to a non-root prefix.

• An Intel-based Mac
• OS X 10.5 or higher
• Command Line Tools for Xcode or Xcode with X11
• Java Developer Update

Open up Terminal.app to get a shell prompt. Copy & paste the following line at the prompt: /usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"

No need to use sudo!

Once installed you can install any software you like as follows:

$ brew install wget
