Does anyone know how to do cartoon shading in POV-Ray? For example, make an
object either 1 color in the light and another in a shadow but also to have
the black lines surrounding the siloute of the object?

MegaPov supports this (though it's based in POV 3.1).

I looked in the features, which one is it?

I'd like to do it in POV-Ray 3.5. I've been able to get the the colors to
look right with some tricks with color_map and the slope modifier but I
can't get the black line siloute.

you can do the "two-color shading" when setting brilliance to 0

for the outline, you'd have to use a PP-Filter of MegaPov ...

  Look at the post-processing section of the help file.

  Very difficult.
