POV-Ray: The Persistence of Vision Raytracer is a high-quality,
totally free tool for creating stunning 3D graphics.
The author of POV-Ray asks users who build their own binaries to
include their name and e-mail in the final result.
The included SlackBuild offers this possibility by entering the
information on the command line like this:
# POVRAY_BUILDER="your name <email@address>" ./povray.SlackBuild
If you leave this variable empty, it's supplied by the
SlackBuild script as "`whoami` on `hostname`"
