Shows the status of a pkgsrc freeze. The typical orange Pkgsrc icon is shown if there is no freeze and a blue icon is shown if there is a freeze. Now there’s no excuse to say you didn’t know the Pkgsrc tree was frozen!
This extension uses the chrome alarm API to make a HEAD request to
http://www.pkgsrc.org/is-a-freeze-on/ to see if there is currently a pkgsrc
freeze. If the ETag changes (or on the first request) we make a full GET and
parse the document body to see if there is a freeze.
