-// Contains the BlimpMessage proto which frames all messages sent over Blimp
-// subchannels. BlimpMessage protos are serialized and transmitted over the
-// wire to the Blimplet server.
-//
-// Each BlimpMessage has a few identifying fields which provide the browser
-// session and tab ID as context. The message details are stored in a
-// feature-specific field (see field IDs 1000 and onward).
-// The |type| field tells the receiving end how the BlimpMessage should
-// be unpacked and which component it should be routed to.
-//
-// CONVENTIONS:
-// * A BlimpMessage can contain only one feature message.
-// * Feature message protos are placed in their own files.
-// * Features are applied to unidirectional channels. Client->server and
-//   server->client channels for a component should be broken out as distinct
-//   features, even if they are conceptually similar.
