		Package pprof serves via its HTTP server runtime profiling data
		in the format expected by the pprof visualization tool.

		The package is typically only imported for the side effect of
		registering its HTTP handlers.
		The handled paths all begin with /debug/pprof/.

		To use pprof, link this package into your program:
		import _ "net/http/pprof"

		If your application is not already running an http server, you
		need to start one. Add "net/http" and "log" to your imports and
		the following code to your main function:

		go func() {
			log.Println(http.ListenAndServe("localhost:6060", nil))
		}()

		If you are not using DefaultServeMux, you will have to register handlers
		with the mux you are using.

		Then use the pprof tool to look at the heap profile:

		go tool pprof http://localhost:6060/debug/pprof/heap

		Or to look at a 30-second CPU profile:

		go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30

		Or to look at the goroutine blocking profile, after calling
		runtime.SetBlockProfileRate in your program:

		go tool pprof http://localhost:6060/debug/pprof/block

		Or to look at the holders of contended mutexes, after calling
		runtime.SetMutexProfileFraction in your program:

		go tool pprof http://localhost:6060/debug/pprof/mutex

		The package also exports a handler that serves execution trace data
		for the "go tool trace" command. To collect a 5-second execution trace:

		curl -o trace.out http://localhost:6060/debug/pprof/trace?seconds=5
		go tool trace trace.out

		To view all available profiles, open http://localhost:6060/debug/pprof/
		in your browser.

Package-Level Functions (total 12, in which 6 are exported)

	 func Cmdline(w http.ResponseWriter, r *http.Request)
		Cmdline responds with the running program's
		command line, with arguments separated by NUL bytes.
		The package initialization registers it as /debug/pprof/cmdline.

	 func Handler(name string) http.Handler
		Handler returns an HTTP handler that serves the named profile.

	 func Index(w http.ResponseWriter, r *http.Request)
		Index responds with the pprof-formatted profile named by the request.
		For example, "/debug/pprof/heap" serves the "heap" profile.
		Index responds to a request for "/debug/pprof/" with an HTML page
		listing the available profiles.

	 func Profile(w http.ResponseWriter, r *http.Request)
		Profile responds with the pprof-formatted cpu profile.
		Profiling lasts for duration specified in seconds GET parameter, or for 30 seconds if not specified.
		The package initialization registers it as /debug/pprof/profile.

	 func Symbol(w http.ResponseWriter, r *http.Request)
		Symbol looks up the program counters listed in the request,
		responding with a table mapping program counters to function names.
		The package initialization registers it as /debug/pprof/symbol.

	 func Trace(w http.ResponseWriter, r *http.Request)
		Trace responds with the execution trace in binary form.
		Tracing lasts for duration specified in seconds GET parameter, or for 1 second if not specified.
		The package initialization registers it as /debug/pprof/trace.

	/* 6 unexporteds ... *//* 6 unexporteds: */
	 func collectProfile(p *pprof.Profile) (*profile.Profile, error)
	 func durationExceedsWriteTimeout(r *http.Request, seconds float64) bool
	 func indexTmplExecute(w io.Writer, profiles []profileEntry) error
	 func init()
	 func serveError(w http.ResponseWriter, status int, txt string)
	 func sleep(r *http.Request, d time.Duration)
