+// Developer tools consist of following parts:
+//
+// ToolsAgent lives in the renderer of an inspected page and provides access to
+// the pages resources, DOM, v8 etc. by means of IPC messages.
+//
+// ToolsClient is a thin delegate that lives in the tools front-end renderer and
+// converts IPC messages to frontend methods calls and allows the frontend to
+// send messages to the ToolsAgent.
+//
+// All the messages are routed through browser process.
+//
+// Chain of communication between the components may be described by the
+// following diagram:
