Building:
* run "ant concat"
* Creates a platform-agnostic "dist/env.js" file and a Rhino-specific "dist/env.rhino.js" file.
Testing:
* run "ant test"
Installing:
1) Include the proper env.js file for your platform.
    load('env.rhino.js'); //if in a Rhino script
2) Tell env.js to load an HTML file from your file system that it should model:
    window.location = "some/file.html";
3) Optionally trigger "document ready" events in one of these ways:
  a) standard window.load method:
    load('env.rhino.js');
    window.onload = function() { /* do something after DOM is loaded */};
    window.location = "some/file.html";
    
  b) jQuery ready method:
    load('env.rhino.js');
    load('jquery-1.2.6.js');
    window.location = "some/file.html";
    load('some-code-that-sets-up-jquery-onready-behaviors.js')
    jQuery.ready();
  c) Other JavaScript frameworks have their own methods of setup, but the general pattern is:
    // load env.js
    // load your framework
    // tell env.js the base DOM to model
    // run any setup code for your framework
    // tell the framework that the document is loaded
    
Testing jQuery Compatibility:
* run ./bin/test-jquery.sh 1.2.6
* run ./bin/test-jquery.sh 1.3.1
* Checks out the given jQuery tag from Subversion into test/vendor/jQuery/[version], moves dist/env.rhino.js into
the correct location in their tree, and runs the test suites.
