--This is another --lua-exec demo. It displays a menu to a user, waits for her
--input and makes a decision according to what the user entered. All happens
--in an infinite loop.

  print "1. Repeat the menu."

  --that keeps consuming system resources when the connection gets broken.
  --Ncat's subprocesses are NOT killed in this case!
