44 Hacks to turn this into a test frame for cursor movement:
45 Eric S. Raymond <esr@snark.thyrsus.com>
48 July 1995 (esr): worms is now in living color! :-)
51 -f fill screen with copies of 'WORM' at start.
52 -l <n> set worm length
53 -n <n> set number of worms
54 -t make worms leave droppings
55 -T <start> <end> set trace interval
56 -S set single-stepping during trace interval
57 -N suppress cursor-movement optimization
59 This program makes a good torture-test for the ncurses cursor-optimization
60 code. You can use -T to set the worm move interval over which movement
61 traces will be dumped. The program stops and waits for one character of
62 input at the beginning and end of the interval.
