You guys really don't get it do you ? I do indent when "I" feel it
will really help in understanding the code. I generaly will only do
so however when the code I am writing is so damn confusing there is
no other way to format it. Take the following as an example where I
was forced to apply some form of indenting. There was little choice
in the matter becasue I kept loosing myself when developing it. You
may look at and think that it is not indented properly but I find it
quit understandable in it's present form.


  The following is from a section of a tutorial I am writting on the gradient
pattern.

 #declare P1 = pigment{rgbf< 1, 1, 1,.3>}
 #declare P2 = pigment{rgbf< 0, 0, 0, 0>}
 #declare P3 = pigment{rgbf< 1, 1, 1, 0>}
 #declare P4 = pigment{rgbf< 0, 0, 0, 0>}

 #declare N1 = normal {gradient y 0.5}
 #declare N2 = normal {gradient x 1.0}

 #declare Checked1 =
