-// Interface for web intent "services" that act as handlers for
-// web intents invoked by client code or other means. "services" can
-// be implemented in a variety of means across different "host" environments
-// Examples:
-// * In another tab, where the tab hosts a web page that services the
-//   intent.
-// * In the Chrome browser where a file picker can be used to select
-//   a file from disk in response to a "pick" action.
-// * In the underlying OS where a native application could be used
-//   to handle an intent.
-//
-// A "service" is selected by policy, based on a heuristic including:
-// user selection, system defaults, declaration as an "explicit" intent
-// by client code, and other means. This selection process is managed
-// by WebInentPickerController.
-//
-// A service, once selected, is responsible for responding to an intent.
-// The "intent" is presented to the service as an instance of
-// WebIntentsDispatcher. The dispatcher provides access to the intent data
-// in the form of a webkit_glue::WebIntentData. The dispatcher also provides
-// the service a means of responding to the intent.
-//
-// A service instance is owned by WebIntentPickerController. Its lifetime is a
-// subset of the life of an intent. It will be created immediately prior
-// to calling HandleIntent, and destroyed immediately after SendReply
-// is called.
-//
-// For details see content::WebIntentsDispatcher and webkit_glue::WebIntentData
