Request a system variable to test whether a scene file has been included by another scene file.
For instance:

camera {...}
#end

Determining if a file should be rendered
can be solved with the Declare INI
option. Declare some variable there and
in every file check for it before
including any other file. Undef it as
one of the first things in the file, so
it remains seen only the the main POV
file.
what is wrong with the #ifdef ?
The ancillary file might #define some identifier, and the main file can test for its existence.
Am I missing a clue ?
As far as I understand, the request is not for a way to test whether e.g. "colors.inc" has been included, but rather whether the file currently being parsed is the main scene file or an included file instead.
Hmmm ... I read it as Grimbert did ... as a matter of fact already I mentioned this to Mike.
Christoph is correct. It is for the file currently being parsed.
I am not sure this feature would be useful. Usually files to render have a pov extension and include files have an inc extension. So having a stub pov file that declares some variable would solve the problem.
The .inc and .pov naming scheme breaks down for files that can be rendered by themselves as well by inclusion. Please don't suggest a broken solution.

Not sure I follow you. Could you provide an example in SDL?
