======================= INFO =========================
This binary is built for AFL-fuzz.
To run the target function on individual input(s) execute this:
  /out/wpantund-fuzz < INPUT_FILE
or
  /out/wpantund-fuzz INPUT_FILE1 [INPUT_FILE2 ... ]
To fuzz with afl-fuzz execute this:
  afl-fuzz [afl-flags] /out/wpantund-fuzz [-N]
afl-fuzz will run N iterations before re-spawning the process (default: 1000)
