                         GENERAL LICENSE AGREEMENT

THIS NOTICE MUST ACCOMPANY ALL OFFICIAL OR CUSTOM PERSISTENCE OF VISION
FILES. IT MAY NOT BE REMOVED OR MODIFIED. THIS INFORMATION PERTAINS TO ALL
USE OF THE PACKAGE WORLDWIDE.  THIS DOCUMENT SUPERSEDES ALL PREVIOUS
GENERAL LICENSES OR DISTRIBUTION POLICIES. ANY INDIVIDUALS, COMPANIES OR
GROUPS WHO HAVE BEEN GRANTED SPECIAL LICENSES MAY CONTINUE TO DISTRIBUTE

This document pertains to the use and distribution of the Persistence of
Vision(tm) Ray Tracer a.k.a POV-Ray(tm). It applies to all POV-Ray program
source files, executable (binary) files, scene files, documentation files,
help file, bitmaps and INI files contained in official POV-Ray Team(tm)
archives.  All of these are referred to here as "the software".

All of this software is Copyright 1991,1996 by the POV-Ray Team(tm).
Although it is distributed as freeware, it is NOT PUBLIC DOMAIN.

The copyrighted package may ONLY be distributed and/or modified according
to the license granted herein.  The spirit of the license is to promote
POV-Ray as a standard ray tracer, provide the full POV-Ray package freely
to as many users as possible, prevent POV-Ray users and developers from
being taken advantage of, enhance the life quality of those who come in
contact with POV-Ray.  This license was created so these goals could be
realized.  You are legally bound to follow these rules, but we hope you
will follow them as a matter of ethics, rather than fear of litigation.


                             USAGE PROVISIONS

Permission is granted to the user to use the software and associated files
in this package to create and render images. The use of this software for
the purpose of creating images is completely free. The creator of a scene
file and the image created from the scene file, retains all rights to the
image and scene file they created and may use them for any purpose
commercial or noncommercial.

The user is also granted the right to use the scenes files, fonts, bitmaps,
and include files distributed in the INCLUDE, TEXSAMPS and POV3DEMO sub-
directories in their own scenes.  Such permission does not extend to files
in the POVSCN sub-directory.  POVSCN files are for your enjoyment and
education but may not be the basis of any derivative works.


                    GENERAL RULES FOR ALL DISTRIBUTION

The permission to distribute this package under certain very specific
conditions is granted in advance, provided that the following conditions
are met.

These archives must not be re-archived using a different method without the
explicit permission of the POV-Team.  You may rename the archives only to
meet the file name conventions of your system or to avoid file name
duplications but we ask that you try to keep file names as similar to the
originals as possible.  (For example:POVSRC.ZIP to POVSRC30.ZIP)

Ready-to-run unarchived distribution on CD-ROM is also permitted if the
files are arranged in our standard directory or folder structure as though
it had been properly installed on a hard disk.

You must distribute a FULL PACKAGE of files as described in the next
section.  No portion of this package may be separated from the package and
distributed separately other than under the conditions specified in the
provisions given below.

Non-commercial distribution in which no money or compensation is charged
(such as a user copying the software for a personal friend or colleague) is
permitted with no other restrictions.

Teachers and educational institutions may also distribute the material to
students and may charge minimal copying costs if the software is to be used
in a course.


                       DEFINITION OF "FULL PACKAGE"

POV-Ray is contained in two sets of archives for each hardware platform.
A "full package" consists of either:

      1) End user executable archives containing an executable program,
         documentation, and sample scenes but no source.

                                  - or -

      2) Programmer archives containing full source code but no executable.
         Also you must include an archive containing documentation, and
         sample scenes.  On some platforms, the documentation and sample
         scenes are archived separately from the source.  Source alone
         is not sufficient.  You must have docs and scenes.

POV-Ray is officially distributed for MS-Dos; Windows 32-bit; Linux for
Intel x86 series; Apple Macintosh; Apple PowerPC; SunOS; and Amiga.  Other
systems may be added in the future.

Distributors need not support all platforms but for each platform you
support you must distribute a full package.  For example a Macintosh only
BBS need not distribute the Windows versions.

This software may ONLY be bundled with other software packages according to
the conditions specified in the provisions below.


         CONDITIONS FOR SHAREWARE/FREEWARE DISTRIBUTION COMPANIES

Shareware and freeware distribution companies may distribute the software
included in software-only compilations using media such as, but not limited
to, floppy disk, CD-ROM, tape backup, optical disks, hard disks, or memory
cards.  This section only applies to distributors of collected programs.
Anyone wishing to bundle the package with a shareware product must use the
commercial bundling rules.  Any bundling with books, magazines or other
print media should also use the commercial rules.

You must notify us that you are distributing POV-Ray and must provide us
with information on how to contact you should any support issues arise.

No more than five dollars U.S. ($5) can be charged per disk for the copying
of this software and the media it is provided on. Space on each disk must
be used as fully as possible.  You may not spread the files over more disks
than are necessary.

Distribution on high volume media such as backup tape or CD-ROM is
permitted if the total cost to the user is no more than $0.08 U.S. dollars
per megabyte of data.  For example a CD-ROM with 600 meg could cost no more
than $48.00.


       CONDITIONS FOR ON-LINE SERVICES AND BBS'S INCLUDING INTERNET

On-line services, BBS's and internet sites may distribute the POV-Ray
software under the conditions in this section.  Sites which allow users to
run POV-Ray from remote locations must use separate provisions in the
section below.

The archives must all be easily available on the service and should be
grouped together in a similar on-line area.

It is strongly requested that sites remove prior versions of POV-Ray to
avoid user confusion and simplify or minimize our support efforts.

The site may only charge standard usage rates for the downloading of this
software. A premium may not be charged for this package. I.E. CompuServe or
America On-Line may make these archives available to their users, but they
may only charge regular usage rates for the time required to download.


                   ONLINE OR REMOTE EXECUTION OF POV-Ray

Some internet sites have been set up so that remote users can actually run
POV-Ray software on the internet server.  Other companies sell CPU time for
running POV-Ray software on workstations or high-speed computers.  Such use
of POV-Ray software is permitted under the following conditions.

Fees or charges, if any, for such services must be for connect time,
storage or processor usage ONLY.  No premium charges may be assessed for
use of POV-Ray beyond that charged for use of other software.  Users must
be clearly notified that they are being charged for use of the computer and
not for use of POV-Ray software.

Users must be prominently informed that they are using POV-Ray software,
