 # Products and versions:
 #   Each policy has the list of products and version numbers where it is
 #   supported under the key 'supported_on'. Each item of this list has the
 #   form of 'product:since_version-until_version', which means that support
 #   for the policy in 'product' was introduced in 'since_version' and removed
 #   after 'until_version'. Product names may contain a suffix specifying a
 #   platform name, e.g.: 'chrome.win' is read as 'Chrome on Windows'. Version
 #   numbers can be any string that does not contain ':' or '-' characters.

-# Currently supported product names:
-#     'chrome_frame', 'chrome_os'
