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