I for one wouldn't even want to begin such a monumental task as this kind of
thing being talked about.  Take for instance the descrepency between the
Windows platform of POV-Ray Insert menu, which shows a 'blob' to be:

// create a smooth blobby shape
#declare StrengthVal = 1.0 // (+ or -) strength of component's radiating
density
#declare RadiusVal   = 1.0 // (0 < RadiusVal) outer sphere of influence on
other components
blob
{
  // threshold (0.0 < threshold <= StrengthVal) surface falloff threshold #
  threshold 0.6
  sphere { < 0.75,   0,    0>, StrengthVal, RadiusVal }
  sphere { <-0.375,  0.65, 0>, StrengthVal, RadiusVal }
  sphere { <-0.375, -0.65, 0>, StrengthVal, RadiusVal }
  cylinder { -z, +z, 0.1, StrengthVal, RadiusVal }
  // [sturm]
  scale 2
}

And the Scene Help shows it as:

BLOB:

blob { BLOB_ITEM... [BLOB_MODIFIERS...]}

BLOB_ITEM:

sphere{<Center>, Radius, [ strength ] Strength [COMPONENT_MODIFIER...] } |
cylinder{<End1>, <End2>, Radius, [ strength ] Strength
[COMPONENT_MODIFIER...] } |
component Strength, Radius, <Center> |
threshold Amount

COMPONENT_MODIFIER:

TEXTURE | PIGMENT | NORMAL | FINISH | TRANSFORMATION

BLOB_MODIFIER:

hierarchy [Boolean] |
sturm [Boolean] |
OBJECT_MODIFIER

 Notice the strength and radius reversal (and why hasn't that been corrected
yet? :^D
  It would be a daunting task to get a book made on POV-Ray whether it be
about the source or the program scripting and expect it to be 100% correct.
I know I'm just a pessimist, so aside from this I'm behind anyone all the
way on the project.
