Well...maybe only produce the scene file if none of the variables are 
set. This won't work for macros, though.
Maybe call an Init() macro after including the file to set up variables 
and turn the example scene off.
Or maybe have a variable telling the include which sample to use...if 
not declared, no sample would be used.
Anyway, in my opinion, it is a much better idea to have separate 
examples. It won't be any harder to do, and it will be easier on the 
user and anyone trying to understand either the examples or the utility. 
And it allows multiple samples.

Scene-files. The povray.binaries.utilities group is for stuff not 
written in POV-Script, and the povray.*.scene-files groups are really 
for any POV-Script files or code snippets.
