-// ScopedTracker instruments a region within the code if the instrumentation is
-// enabled. It can be used, for example, to find out if a source of jankiness is
-// inside the instrumented code region.
-// Details:
-// 1. This class creates a task (like ones created by PostTask calls or IPC
-// message handlers). This task can be seen in chrome://profiler and is sent as
-// a part of profiler data to the UMA server. See profiler_event.proto.
-// 2. That task's lifetime is same as the lifetime of the ScopedTracker
-// instance.
-// 3. The execution time associated with the task is the wallclock time between
-// its constructor and destructor, minus wallclock times of directly nested
-// tasks.
-// 4. Task creation that this class utilizes is highly optimized.
-// 5. The class doesn't create a task unless this was enabled for the current
-// process. Search for ScopedTracker::Enable for the current list of processes
-// and channels where it's activated.
-// 6. The class is designed for temporarily instrumenting code to find
-// performance problems, after which the instrumentation must be removed.
