| 22 | .SH DESCRIPTION | |
| 23 | .ad b | |
| 24 | Brian Horn (cithep!bdh) showed me a | |
| 25 | .I TOPS-20 | |
| 26 | program on the DEC-2136 machine called | |
| 27 | .IR WORM , | |
| 28 | and suggested that I write a similar program that would run under | |
| 29 | .IR Unix . | |
| 30 | I did, and no apologies. | |
| 31 | .PP | |
| 32 | .B -field | |
| 33 | makes a "field" for the worm(s) to eat; | |
| 34 | .B -trail | |
| 35 | causes each worm to leave a trail behind it. You can figure | |
| 36 | out the rest by yourself. | |
