Hi All,

I'm rewriting the parser for my pov2mesh application
(http://www.geocities.com/psenzee/pov2mesh/) and I've got a question about
how directives are handled in pov.  Are the directives in POV a logically
separate phase like a C preprocessor?

In the pov bnf, things like

#if ( BOOL )  TOKENS ...

lead me to believe that it's a separate phase, but then there are other
restrictions on when and where certain directives can be used that are not
consistent with a separate 'preprocessor'.  Any info about this would be
great!

Thanks!
