worms - animate worms on a display terminal SYNOPSIS
/usr/games/worms [ -field ] [ -length # ] [ -number # ] [ -trail ] DESCRIPTION
Brian Horn (cithep!bdh) showed me a TOPS-20 program on the DEC-2136 machine called WORM, and suggested that I write a similar program that would run under Unix. I did, and no apologies. -field makes a "field" for the worm(s) to eat; -trail causes each worm to leave a trail behind it. You can figure out the rest by your- self. FILES
