The first paragraph describes the hierarchy as follows:
World
...Group "Model"
......Group "Objects"
.........Group"STR0"
............Object "WHATEVER" /* this can be a living shape */
............Object "WHATEVER2" /* if there is a dead shape, it would be this object with the DEAD flag set */
.........Object "STR1"
.........Object "STR2"
.
.
.
Yet the section on Types reads like this:
"...if you have 4 "STR" types and 2 "BRR" types, they would be named as follows: STR1, STR2, STR3, STR4, BRR1, BRR2 and so on."
So does the numbering start at 0 or 1?
