  32 """Simple testing harness for native client modulers running under sel_ldr
  33
  34 The tool expects 5 arguments (in this order):
  35
  36
  37 * path to sel_ldr executable
  38 * the native client module
  39 * a sequence of rpc calls in plain text (e.g. tests/mandel/test.stdin)
  40 * the expected out put (e.g. tests/mandel/test.stdout)
  41 * a regex to filter the actual output (NYI)
  42
  43 The tool reports failure if the native client module exits with
  44 an nonzero exit code or if actual and expected output do not match
