   3 # A little script to run tshark on capture file[s] (potentially ones that
   4 # failed fuzz testing). Useful because it sets up ulimits and other environment
   5 # variables for you to ensure things like misused ephemeral memory are caught.
   6 # (I'm writing this after having my machine hang up for like 15 minutes because
   7 # I wasn't paying attention while tshark was running on a fuzzed capture and
   8 # it used all my RAM + swap--which was pretty painful.)
