Is it possible to see the resulting raw POV code
after all macro expansions and include file inclusion ?
Just like "cc -p" or "gcc -E" for a C file.

Thank you for the concise answer!
Do you know why ?
Am I the first to ask ?
Is it difficult to implement because of the way the parser works ?
Would anyone be interested in such functionality ?
I haven't been able to find any discussions about the subject.
I was looking for a way to debug a large complex set of macros.

Because it is not needed.
POV-Ray doesn't have a preprocessor like a C compiler has. POV-Ray
directly reads and interprets the SDL code without doing any
preprocessing to it.
> Am I the first to ask ?
I remember people asking if POV-Ray could just parse but not
render and return an error code (which could be used to check
the validity of the input), but I don't remember anyone asking
if POV-Ray could be used as a "preprocessor".

It would not be difficult at all to implement, but it would be
rather useless (at least for POV-Ray itself).
I can think of only one useful use for this feature: To convert
SDL files to a simplified format which is easier to parse by
third-party programs.
