I’ve recently installed POV-Ray 3.7 for Unix, and one of the first
things I did afterwards was to run the scripts “allanim.sh”,
“allscene.sh” and “portfolio.sh” to generate HTML documents showcasing
the ray tracer’s capabilities.  I ran into the “reflection.ini” issue
reported by ThH nearly four years ago, as well as a few that don’t seem
to have been mentioned or fixed anywhere.  The attached archive contains
the following files edited by me from the ones in the 3.7.0 release.
Maybe I should have used the 3.8.0 ones instead, but I’ve read
_somewhere_ that branch has been more or less abandoned.

• povray/unix/scripts/allscene.sh

The calling conventions detailed in the comments specify eight possible
arguments, but the script only took six into account, ignoring the rest.
I noticed the problem when the script failed to make an HTML file.

• povray/distribution/scenes/animations/float2/float2.pov

Missing “equals” sign in the text object showing the ‘inc’ function.

• povray/distribution/scenes/animations/float4/float4.pov

In the text object, “atan2(B,C)” should be “atan2(B,A)”, which is the
value actually calculated.

• povray/distribution/scenes/portfolio/allobjects.pov

The macro ‘Sphere_Of_Spheres’ created two coïncident copies of each of
the spheres lying on either of the two first meridians, and did not
check that there was enough room around the poles.  For instance, in
this scene itself, there were two spheres very visibly colliding at the
pole facing the viewer.

I’ve included two images made with the original macro and the fixed one,
in the “allobjects_images” folder.  In the latter, you need to pay very
close attention to notice the pole at all, revealed only by the slightly
wider space around one sphere, which already happened anyway when a
parallel’s length is close to allowing an extra sphere, but not quite
there.

• povray/distribution/scenes/portfolio/readme.txt

Repeated word _and_ in the third line (second non-empty one).
