title: Building an iPhone application from the command line, without xcodebuild
body: <p>It is possible to build an iPhone application manually, without using <code>xcodebuild</code> nor an Xcode project?</p>
  
  <p>The idea is to build the application using SCons without creating an Xcode project. I know there is the <code>codesign</code> command line tool, that I could use, but before I start reverse engineering the Xcode build process, I was wondering if anybody has experience with this or has done it before.</p>
