ShadowMaster is a tool that makes getting interesting screen saver
graphics running easier than it is with stock AmigaDOS. All the owrk
of watching the input stream, starting and stopping the graphics is
done for you. All you have to do is open a screen and draw into it,
while watching for a Control-C signal. I've even provided templates
for doing such.

In one sense, ShadowMaster is freeware. The freely distributable
package is in no way crippled or a "demo" version. However,
ShadowMaster is shareware in sense closer to the meaning of the word
than most packages distributed with that label; I want people to share
screen saver modules with me, and to allow me to share them with
others. To encourage that, the freely distributable package has only a
small number of savers. A larger collection - along with the latest
version of ShadowMaster - can be obtained by sending me a new saver
for that collection. For those whose talents don't lean towards
graphics code, a cash contribution can be made instead. See the file
Distribution for details.

Start by reading the file docs/Install. docs/ShadowMaster is probably a
good bet for the next thing to read, with docs/ScreenSaver being a
close second.

The file freebiez.lzh in the commercial version is the freely
distributable version of shadowmaster. Feel free to give it to all
your friends. In fact, you'd be doing me a favor by spreading it as
far as possible.
