[R-SIG-Mac] Fully contained R.app

This is a very nice entry to the faq. Thanks Simon.

btw, wouldn't it be possible to create a small app (with an embedded  
script) to do this?
Which possibly makes a copy of R.app, so if you discover you need a  
additional package, you  install it in the original R.app and repackage.

p.s. I'm not volunteering though :)
