   5 // Developer tools consist of the following parts:
   6 //
   7 // DevToolsAgent lives in the renderer of an inspected page and provides access
   8 // to the pages resources, DOM, v8 etc. by means of IPC messages.
   9 //
  10 // DevToolsClient is a thin delegate that lives in the tools front-end
  11 // renderer and converts IPC messages to frontend method calls and allows the
  12 // frontend to send messages to the DevToolsAgent.
  13 //
  14 // All the messages are routed through browser process. There is a
  15 // DevToolsManager living in the browser process that is responsible for
  16 // routing logistics. It is also capable of sending direct messages to the
  17 // agent rather than forwarding messages between agents and clients only.
  18 //
  19 // Chain of communication between the components may be described by the
  20 // following diagram:
