What is homebrew?

Homebrew is a tool that lets you install software on your Mac from the command line. Instead of hunting around websites for download links, dragging apps into your Applications folder, or dealing with installers, you just type a simple command and the tool handles downloading, installing, and configuring everything for you. It works by tapping into a large collection of open-source packages and applications that have been packaged up for easy installation. You can search for whatever you need, and the system will fetch it and set it up on your computer. It also helps keep your installed software up to date, so you do not have to manually track down new versions yourself. If you run into trouble, it includes built-in diagnostic tools to help figure out what went wrong. This is primarily aimed at developers and technical Mac users who want a faster, more consistent way to manage their software tools. For example, a web developer might use it to quickly install a database or a programming language without going through a complex setup process. It is meant to fill a gap, since Macs did not historically come with a built-in package manager the way some other operating systems do. The project is written in Ruby and is maintained by a group of core contributors, with the original version created by Max Howell. The README does not go into detail on the specific technical tradeoffs, but it points users to a wiki and external documentation site for more in-depth information.
