Netshade is a program for creating realistic looking raytraced images.
It is based on 
Rayshade 4.0.6 by Craig Colb.  Craig gave the net permission to release a
program derrived from Rayshade, but with all the modifications posted
and mailed in from the Rayshade users.  Thus, Netshade.

The majority of this document is based on Craig's draft of the
Rayshade User's Guide, with the name changed from Rayshade to
Netshade.  This does not mean there is nothing new -- there are quite
a few new features which are documented here.

As Netshade is a derrived work, future versions of Rayshade may not be
compatible with Netshade, and future versions of Netshade may diverge
further from Rayshade 4.0.6.  I hope that both programs can share
ideas and become more than either would have alone.

Netshade has not been directly run past Craig Kolb, and he is not
directly responsible for anything in Netshade.  Any bugs there are
to report should go to me, preferably with fixes.

The copyright on the majority of the code contained within Rayshade
(and therefore Netshade) prohibits commercial use.  Please read those
notices if you are unsure if that applies to you.

Please note that this is a draft document as well -- if I have omitted
anything, please let me know.  Suggestions welcome, as is constructive
critisim.
