// Developer tools consist of the following parts:
//
// DevToolsAgent lives in the renderer of an inspected page and provides access
// to the pages resources, DOM, v8 etc. by means of IPC messages.
//
// DevToolsClient is a thin delegate that lives in the tools front-end
// renderer and converts IPC messages to frontend method calls and allows the
// frontend to send messages to the DevToolsAgent.
//
// All the messages are routed through browser process. There is a
// DevToolsManager living in the browser process that is responsible for
// routing logistics. It is also capable of sending direct messages to the
// agent rather than forwarding messages between agents and clients only.
//
// Chain of communication between the components may be described by the
// following diagram:
// ----------------------------
// | (tools frontend |
// | renderer process) |
// | | --------------------
// |tools <--> DevToolsClient+<-- IPC -->+ (browser process) |
