Well, I tried this:

#version unofficial MegaPov 0.5;
#warning concat("Version Value is:",str(version,0,3),"\n")

The value printed was 3.100 in MegaPOV

Then I tried
#warning concat("Version Value is:",str(version,0,3),"\n")
in Official POV and got 3.100.

It didn't help.
Is there any way for the scene file to
recognize that it is on the official as opposed to MegaPOV?
