Well - that one is difficult.  When i had a look at it i found it quite 
badly designed (or at least unusual).  The syntax was not easy to use 
and misleading - specifying functions instead of floats without a 
wrapping function{} is not a good idea (*).   Also i think Mael 
considered it incomplete - he wanted to add support for anisotropic 
finishes IIRC.

In fact 'finish map' is a misleading name - a finish map would be 
something like:

texture {
   pigment { ... }
   finish {
     bozo
     finish_map {
       [0 Fin_1][1 Fin_2]
     }
   }
}

(*) if it is nor clear what i mean imagine the following variation of 
the sample in the MlPOV manual:

#declare fct = function { pigment { checker color rgb 0 color rgb 1 
scale .1 } }

sphere { ...
   finish {
     uv_mapping
     reflection { fct (1) }
   }

Should that be an incorrect call to function fct() or a function based 
reflection minimum and a constant reflection maximum?
