title: How to uninstall Homebrew Cask
body: <p>I installed Homebrew Cask for kicks as described at <a href="http://caskroom.io/">http://caskroom.io/</a>. It boils down to the following command:</p>
  
  <pre><code>$ brew install caskroom/cask/brew-cask
  $ brew tap caskroom/versions
  </code></pre>
  
  <p>Homebrew Cask installed and everything was fine. Then I uninstalled Homebrew Cask like so:</p>
  
  <pre><code>$ brew untap caskroom/versions
  $ brew uninstall brew-cask
  </code></pre>
  
  <p>Here are the current taps:</p>
  
  <pre><code>$ brew tap
  homebrew/versions
  </code></pre>
  
  <p>Yet I see stuff from Cask when searching for items that wouldn't be part of Homebrew itself (like Graphical programs, aText, Fantastical etc.):</p>
  
  <pre><code>$ brew search atext
  Caskroom/cask/atext
  </code></pre>
  
  <p>Though it doesn't install (as expected):</p>
  
  <pre><code>$ brew install atext 
  Error: No available formula for atext
  Searching formulae...
  Searching taps...
  Caskroom/cask/atext
  </code></pre>
  
  <p>So the question is why does brew search Caskroom/cask and how do I get rid of it (I don't want Homebrew telling me it has aText, for example, when it can't install it)?</p>
  
  <p>I am running Mac OS X Yosemite.</p>
