-Options:
-       -f                      fill screen with copies of 'WORM' at start.
-       -l <n>                  set worm length
-       -n <n>                  set number of worms
-       -t                      make worms leave droppings
-       -T <start> <end>        set trace interval
-       -S                      set single-stepping during trace interval
-       -N                      suppress cursor-movement optimization

   This program makes a good torture-test for the ncurses cursor-optimization
   code.  You can use -T to set the worm move interval over which movement
   traces will be dumped.  The program stops and waits for one character of
   input at the beginning and end of the interval.
