    HOW TO RUN THIS SCRIPT:
    Wireshark and Tshark support multiple ways of loading Lua scripts: through
    a dofile() call in init.lua, through the file being in either the global
    or personal plugins directories, or via the command line. The latter two
    methods are the best: either copy this script into your "Personal Plugins"
    directory, or load it from the command line.
