(might need to be clarified, but this Rakefile only applies to BubbleWrap's test project, it isn't how BubbleWrap actually gets included with other projects, which is in [`lib/bubble-wrap/ext/motion_project_app.rb`](https://github.com/rubymotion/BubbleWrap/blob/osx/lib/bubble-wrap/ext/motion_project_app.rb))
