 '''Publishes ChromeVox to the webstore.
   Given an unpacked extension, compresses and sends to the Chrome webstore.
 
   Releasing to the webstore should involve the following manual steps before
       running this script:
     1. clean the output directory.
     2. make a release build.
     3. run manual smoke tests.
     4. run automated ChromeVox tests.
