- advantage of, enhance the life quality of those who come in contact with
- POV-Ray. This legal document was created so these goals could be realized.

- conditions specified in the guidelines below.

-

- the materials or has the right to distribute these materials. He
- authorizes the POV-Team to use the materials any way they like. The
- contributor still retains rights to the donated material, but by donating
