Program: PNG
Author: J L Frost Chevron Reserch Company
Submitted by: Robin Miller Project Software & Development, Inc.

PNG is a video ping pong program which was written by J L Frost at
the Chevron Research Company. It original ran only on the VT52
series terminal. I've modified it to run on the VT100 terminal as well.
The VT52 code still exists and is conditionalized by the symbol VT52.
The program starts off with a help page to explain how to run the game.
