Excellent, thanks!

As I said earlier I don't think osx/cocoa.rb is a good idea, I would  
prefer rubycocoa.rb instead.

This is a temporarily compatible layer, designed to help people port  
their RubyCocoa app to MacRuby. The purpose is not to provide a layer  
on which people can rely on eternally. So having developers explicitly  
require rubycocoa.rb is better IMHO (and anyway, in the most cases,  
this will be an Xcode app that has to be modified to link against  
MacRuby.)

Also, I don't think it's a good idea to duplicate the whole osx/*.rb  
environment then.

I will address these.

Regarding your commit:

- could you install the layer as part of instruby.rb instead? And  
respect destdir.

- I wonder if it's necessary to commit the RubyCocoa samples in sample- 
macruby as you did. Ultimately we might be able to run all RubyCocoa  
samples, but we probably don't want to have all of them in macruby- 
sample, right? Maybe some of the samples could be moved in the test  
directory, for testing purposes?

I think people will be confused to see a RubyCocoa directory in / 
Developer/Examples/Ruby/MacRuby.
