About This File
This file contains 6 PWADS for DOOM that, unless I've missed a bug,
are without bugs. Intentionally, they are very basic and short. They
are intended for the beginning DEU user, and illustrate some techniques
that can be used to achieve different effects without too much effort.
The first is the most basic, only two sectors of different heights. After
that, each is a little different and gives an example of a different
feature. I would personally recommend quickly playing each level, and then
looking at the PWAD file with DEU. There are, intentionally, no enemies,
since they are quite easy to add and can get in the way sometimes.
