-# WebappRT doesn't need these instructions, and they don't necessarily work
-# with it, but it does use a GRE directory that the GRE shares with Firefox,
-# so in order to prevent the instructions from being processed for WebappRT,
-# we need to restrict them to the applications that depend on them, i.e.:
-#
-# b2g: {3c2e2abc-06d4-11e1-ac3b-374f68613e61}

-#
-# In theory we should do this for all these instructions, but in practice it is

- // handling feeds of that type, but without a content-type differentiation
- // it is difficult for us to disambiguate.
- //
- // The other problem is that if the user specifies an auto-action handler
- // for one feed application, the fact that the content type is shared means

- // regardless of the content-type.
- //
- // This means that content-type alone is not enough to determine whether

- // to always use this stream converter, even when an auto-action is
- // specified, not the basic one provided by WebContentConverter. This
- // converter needs to consume all of the data and parse it, and based on
- // that determination make a judgment about type.
- //
- // Since there are no content types for this content, and I'm not going to
- // invent any, the upshot is that while a user can set an auto-handler for
- // generic feed content, the system will prevent them from setting an auto-
- // handler for other stream types. In those cases, the user will always see
- // the preview page and have to select a handler. We can guess and show
- // a client handler, but will not be able to show web handlers for those
