description = [[
Prints a list of ports found in each state.

Nmap ordinarily summarizes "uninteresting" ports as "Not shown: 94 closed
ports, 4 filtered ports" but users may want to know which ports were filtered
vs which were closed. This script will expand these summaries into a list of
ports and port ranges that were found in each state.
