Go 1.7 does not require the binary argument.

Supported profile types are:
    - net: network blocking profile
    - sync: synchronization blocking profile
    - syscall: syscall blocking profile
    - sched: scheduler latency profile

Flags:
	-http=addr: HTTP service address (e.g., ':6060')
	-pprof=type: print a pprof-like profile instead
	-d=int: print debug info such as parsed events (1 for high-level, 2 for low-level)
