      3 # android_perf: utility for running perf on an android device
      4 #
      5 # The basic usage sequence is to run...
      6 #  1) perf record [gm/tests/bench] # runs profiler on specified app
      7 #  2) perf report # prints profiler results
      8 #  3) perf clean # cleans the temporary directory used to store results
