===================================================
**********************WARNING**********************
===================================================

It is not recommended that you install Abbot
directly from git. Unless you are hacking on Abbot 
you should use the gem:
 
  gem install sproutcore

===================================================

To get the SproutCore framework, run

  git submodule init
  git submodule update

To update the gem:

  - Update VERSION.yml
  - Run `rake release:all` on Mac OS X or Linux
      This updates the CHANGELOGS for both framework and abbot,
      updates version numbers and tags them. It also builds and
      pushes gems. If you just want to see what it does, pass
      PRETEND=1 to make no actual changes.
      For best results you should have RVM with MRI Ruby and JRuby installed.
  - Once you have verified your changes, run `rake release:push`.
  - On Windows, update the repos and run `rake release:gems:all`
  - To create installer packages, run `rake pkg` on Mac OS X and Windows
