What I actually want is more detail on the return values of the PVC 
macros. Sure, it says that PVC_time_now() returns from 0 to 1, but does 
that mean 0 is 0000 hours and 1 is also 0000 hours with 0.5 being 1200 
hours? When's sunset? When's sunrise?

I assume PVC_weather_forecast(n) returns the same values as 
PVC_weather_now(), but it would be nice to have it explicitly said. 
Also, what are the components of the vector returned by PVC_date_now()? 
<day, month, year>? <month, day, year>? <year, month, day>? And is it 
y2k-compliant? ;-)

Okay, so I'm fussy. I must have picked that up somewhere when I was 
learning C++.

Now I must stop being picky and go model some sculptures. I thought that 
a shop where you can buy glass spheres on chequered planes is a little 
too much for me (at the moment at least, need more POV experience!) but 
I see no reason not to have a glass sphere on a chequered pedestal in 
the middle of a park...
