Just a thought. If the POVRAY (or whatever) sections get too big,
would it make sense to add 0 INCLUDE meta-command so the LDRAW only
programs don't waste time parsing? Then the POV specific versions
could be distributed separately from the main parts. For example:
0 IFDEF POVRAY
0 INCLUDE pov/coolpart.pov
0 ELSE
0 boring LDRAW version of part
...
0 ENDIF
Sorry if this has been discussed to death already...
