Homebrew 与 Homebrew-Cask 的关系

• Remember that Homebrew-Cask is an independent project from Homebrew.
• Homebrew-Cask is implemented as a subcommand of Homebrew.

Homebrew-Cask 介绍（官方主页）：

“To install, drag this icon…” no more!

Homebrew-Cask extends Homebrew and brings its elegance, simplicity, and speed to the installation and management of GUI macOS applications such as Google Chrome and Adium.

We do this by providing a friendly Homebrew-style CLI workflow for the administration of macOS applications distributed as binaries.

It’s implemented as a homebrew external command called cask.

To start using Homebrew-Cask, you just need Homebrew installed.

As of December 2015, it is now unnecessary to install cask manually as it is now part of homebrew's installation. So after updating homebrew via brew update, you are set to use brew cask.
