title: How to associate file type with MacOS X App without launching it first?
body: <p>I would like to associate the <strong>last installed</strong> version of my Mac OS X application with a certain type of file. A little experimentation shows that the <strong>info.plist</strong> file seems to be read and interpreted by the operating system when launching the application, not when dragging the application bundle to the disk. <a href="http://developer.apple.com/DOCUMENTATION/MacOSX/Conceptual/BPRuntimeConfig/BPRuntimeConfig.html#//apple_ref/doc/uid/10000170" rel="nofollow noreferrer">Apple's documentation on run-time configuration</a> does not say much on that topic.</p>
  
  <p>Is there any way, using a simple <code>.dmg</code> image as installation medium, to make sure the system associates that particular file type with my newly installed app <strong>without having to launch it</strong> first?</p>
  
  <p>I should clarify that I want this to be done automatically during the installation (I don't want my users to have to do it themselves).</p>
