title: Accessing Apple Authorization Services with MacRuby
body: <p>I'm working on a MacRuby application that needs to make updates to config files in the /etc directory. In the command line version of the application, this prompts a password and then allows the access.</p>
  
  <p>But now I'm converting the application to a GUI app and I can't figure out how to integrate authorization services into the Ruby application. The example on Apple's Developer website uses Obj-C and C. A large part of the reason I'm using MacRuby is because of how simple file access is in Ruby. I'd rather not have to convert that portion of my application to Obj-C/C. Does anyone have a good example of how to use Authorization Services with MacRuby?</p>
