The section on the looks_like statement is missing an syntax example for
when you are using it properly. I find this statement kind of confusing,
and would like the docs to explain it better.

The content of the inbuilt documentation is maintained on the POV-Ray
Wiki (http://wiki.povray.org); you are more than welcome to actively
contribute to its improvement.

Unfortunately, I am still trying to figure out how it works.

Design an object that looks the way you want the light source to look,
and insert it into the light source as the content of the
"looks_like{...}" block.
The only caveat that I know of is in where to place the object. IIRC it
is auto-translated to the light source position, so you need to design
it as if the light source was at <0,0,0>. I /think/ that little detail
is indeed missing from the docs.

The looks_like coordinates are relative to the light_source to whitch
it's attached.
I think that it was not always the case, but it's the case since version
3.5, or maybe earlier.

I found these two pages which have better examples, but the help file
index does not point to them so I didn't see them at first:
http://www.povray.org/documentation/view/3.6.2/137/
http://www.povray.org/documentation/view/3.6.0/40/
