The timetraveling wormhole analyzer of the old king's secret service is
   a basic signal organizer based on gnuradio.
   It classifies emission bursts, records them in a database, and provides
   an interface to review them.
   They are associated with metadata that can be correlated to identify
   sources.
   I am not immediately building this tool, but it's nice to mention it.
   I'm just trying to troubleshoot a failing board.
