+// This file defines the interface for event tracing in WebRTC.
+//
+// Event log handlers are set through SetupEventTracer(). User of this API will
+// provide two function pointers to handle event tracing calls.
+//
+// * GetCategoryEnabledPtr
+//   Event tracing system calls this function to determine if a particular
+//   event category is enabled.
+//
+// * AddTraceEventPtr
+//   Adds a tracing event. It is the user's responsibility to log the data
+//   provided.
+//
+// Parameters for the above two functions are described in trace_event.h.
