-// Declares a delegate that interacts with the rest of the browser on behalf of
-// the AutomaticProfileResetter.
-//
-// The reason for this separation is to facilitate unit testing. Factoring out
-// the implementation for each interaction step (encapsulated by one method of
-// the delegate) allows it to be tested independently in itself. It also becomes
-// easier to verify that the state machine inside AutomaticProfileResetter works
-// correctly: by mocking out the interaction methods in the delegate, we can, in
-// effect, mock out the entire rest of the browser, allowing us to easily
-// simulate scenarios that are interesting for testing the state machine.
-//
-// The delegate is normally instantiated by AutomaticProfileResetter internally,
-// while a mock implementation can be injected during unit tests.
