-# This script vulcanizes all parts of the polymer library that are included in
-# polymer-elements.in.html. This is required because the polymer library is not
-# CSP compliant and Chrome extensions that use polymer have CSP enforced.
-# The vulcanize tool cannot currently be added to the Chrome build which is why
-# this must be run manually when polymer is revved. This script should be re-run
-# whenever we want polymer is updated.
-#
-# See https://code.google.com/p/chromium/issues/detail?id=359333 for more
-# details.
-#
-# Once this script has been run, the entire polymer library will be inside of
-# polymer-elements.html and polymer-elements.js.
-#
-# TODO(raymes): This is ugly. Remove this as soon as we can fix
-# crbug.com/359333.
