**********************************************************

Now include the jQuery libraries with:

  cd <jq-plugin>
  rake first_time

First time will:
 - add jquery core, ui and base themes
 - compile js to a packed version (see build directory)
 - load three html files in your browser to demon
    1. Acceptance tests
    2. Spec tests
    3. Example page
    
Note: you don't have to add jquery core, ui and themes.
However, if you don't you will need to update the html 
pages (example.html, test/spec.html). To see other options
use rake -T
