Dear POV'ers,

 I am raytracing my object by rotating light_source(point) around
X-axis, Y-axis, or Z-axis based on
Chris Colefax's animation utility.
I'd like to identify each output(PNG) by writing the angle values
somewhere in the corner.
For example, ang. 35(X), or ang. 72(Y), and so on.
 I do not know how I could get the value of the variable during the
animation for each output, and pass
the value to the font.
Any help would be appreciated.
=== part of my animation === there are 8 or 13 frames for each axis.==
// light source rotation around Z-axis 0 to -180degree
light_source { <-86.6,0,-50.0> color rgb<1,1,1>*2.5
             rotate
             From(0.0,< 0,0,0>)
             Using("",1,1,"")
             To(1, <  0,0,-180>)
             }
