title: How do I override the Ruby and Ruby DevKit installdir with Chocolatey?
body: <p>I am somewhat new to chocolatey, having installed a few packages in the past on Windows 8, and I have come to like it.</p>
  
  <p>I have noticed that chocolatey installs the packages in the default Windows program directory (i.e. "Program Files x86" or so). Maybe there is more to that that I am missing.</p>
  
  <p>For the specific case of Ruby 2.1.5 and Ruby DevKit, I have a couple of questions:</p>
  
  <ul>
  <li>How can I ensure I install the x64 versions of Ruby, and Ruby DevKit using chocolatey?</li>
  <li>How can I set a custom installation directory from chocolatey?</li>
  </ul>
  
  <p>I know there is some information about changing the install directory, but the arguments syntax are dependent on the install system used (if any) by the specific package being installed, in this case, Ruby &amp; Ruby DevKit. I am yet to find what would be the CLI installation string for ruby and ruby devkit on windows. Any help is greatly appreciated. Thanks</p>
