Doc on Ting Yang's fire shader

I am trying to document the fire shader (candle type flame) found here http://ting731.com/tingyangRenderman/fire/fire_sourcecode.html
thanks to Ting Yang creating such an wonderful shader.

Kfb: i think its exposure value

freq: 
radius: size of the outer part
radius_mask: inner transparent area's size
offset_radius: negative value decreases the outer transparent area of the flame
offset_radius_a: 
s1: pos x axis
t1: pos y axis
lump:
outsideblur: blurs the outside edge of blue part
insideblur: blurs the inside edge of blue part
outsideblur_f: blurs the edge of flame (white part)
outsideblur_m:
insideblur_m: blurs the inner part of the yellow flame
mask_offset: yellow flame taking over the transparent area under it
a1: increasing this values shows dissappearance of the blue flame
a2: increasing this values shows dissappearance of the blue flame
b1:
b2:
top: color of the yellow flame
bottom: color of the edge of the yellow flame
blueflame: mixes the specified color on top of all
