The POV-Ray v3.6 source code for Unix and Linux systems is in the files
povray-3.6.tar.bz2 and povray-3.6.tar.gz in the ../Unix/ subdirectory.
(These files are identical other than the compression method used to
create them).

The configuration process is explained in the file README contained within
the tarball. Please also read the distribution and source code licences which
are contained within the archive before doing anything with the source code.
