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";
     Envjs("some/file.html");
   Optionally you can turn on/off settings by passing an options object:
     Envjs("some/file.html", {log: function(msg){ console.debug(msg) }});
3) Optionally trigger "document ready" events in one of these ways:
   a) standard window.load method:
     load('env.rhino.js');
     window.location = "some/file.html";
     Envjs("some/file.html");
    
   b) jQuery ready method:
     load('env.rhino.js');
     load('jquery-1.3.2.js');
     Envjs("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 1.3.2
* run ./bin/test-jquery.sh 1.3.1
* run ./bin/test-jquery.sh 1.2.6
* 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.
