    The following is legal information pertaining to the use of the Persis-
 tence of Vision Ray Tracer a.k.a POV-Ray.  It applies to all POV-Ray source
 files, executable (binary) files, scene files, documentation files contained
 in the official POV archives.  Certain portions refer to custom versions of
 the software,  there are specific rules listed below for these versions.
 All of these are referred to here as "the software".

    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 LICEN-
 SES OR DISTRIBUTION POLICIES.

    Permission is granted to the user to use the Persistence of Vision Ray
 tracer and all associated files in this package to create and render images.
 The use of this software for the purpose of creating images is 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 non-commercial.

    The user is also granted the right to use the scenes files and include
 files distributed in the INCLUDE and DEMO sub-directories of the POVDOC ar-
 chive when creating their own scenes.  Such permission does not extend to
 files in the POVSCN archive.  POVSCN files are for your enjoyment and educa-
 tion but may not be the basis of any derivative works.

    This software package and all of the files in this archive are copyright-
 ed and may only be distributed and/or modified according to the guidelines
 listed below.  The spirit of the guidelines below 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 ad-
 vantage 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.  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.

    No portion of this package may be separated from the package and distri-
 buted separately other than under the conditions specified in the guidelines
 below.

    This software may be bundled in other software packages according to the
 conditions specified in the guidelines below.

    This software may be included in software-only compilations using media
 such as, but not limited to, floppy disk, CD-ROM, tape backup, hard disks,
 optical disks, or memory cards.  There are specific rules and guidelines
 listed below for the provider to follow in order to legally offer POV-Ray
 with a software compilation.

    The user is granted the privilege to modify and compile the source for
 their own personal use in any fashion they see fit.  What you do with the
 software in your own home is your business.

    If the user wishes to distribute a modified version of the software (here
 after referred to as a "custom version") they must follow the guidelines
 listed below.  These guidelines have been established to promote the growth
 of POV-Ray and prevent difficulties for users and developers alike.  Please
 follow them carefully for the benefit of all concerned when creating a cus-
 tom version.

    You may not incorporate any portion of the POV-Ray source code in any
 software other than a custom version of POV-Ray.  However authors who con-
 tribute source to POV-Ray may still retain all rights to use their contribu-
 ted code for any purpose as described below.

    The user is encouraged to send enhancements and bug fixes to the POV-
 Team, but the team is in no way required to utilize these enhancements or
 fixes.  By sending material to the POV-Team, the contributor asserts that he
 owns the materials or has the right to distribute these materials.  He
 authorizes the POV-Team to use the materials any way they like.  The contri-
 butor still retains rights to the donated material, but by donating you
 grant equal rights to the POV-Team.  The POV-Team doesn't have to use the
 material, but if we do, you do not acquire any rights related to POV-Ray.
 We will give you credit if applicable.

    The permission to distribute this package under certain very specific
 conditions is granted in advance, provided that the above and following con-
 ditions 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 du-
 plications but we ask that you try to keep file names as similar to the ori-
 ginals as possible.  For example: POVDOC.ZIP to POVDOC20.ZIP.

    You must distribute a full package of archives as described in the next
 section.

    Non-commercial distribution (such as a user copying the software for a
 personal friend or colleague and not charging money or services for that
 copy) has no other restrictions.  This does not include non-profit organiza-
 tions or computer clubs.  These groups should use the Shareware/Freeware
 distribution company rules below.

    The POV-Team reserves the right to withdraw distribution privileges from
 any group, individual, or organization for any reason.

    POV-Ray is contained in 4 archives for each hardware platform.
       1)   An executable archive,
       2)   A documentation archive,
       3)   Sample scene archives,
       4)   Source code archive.

    A "full package" is defined as one of the following bundle options:
       1)   All archives (executable, docs, scenes, source)
       2)   User archives (executable, docs, scenes but no source)
       3)   Programmer archives (source, docs, scenes but no executable)

    POV-Ray is officially distributed for IBM-PC compatibles running MS-Dos;
 Apple Macintosh; and Commodore 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 an IBM-only BBS
 need not distribute the Mac versions.

            the source file FRAME.H and insure that the program prominently
            displays this information.
       7)   Include all credits and credit screens for the official version.
       8)   Include a copy of this document.

    Vendors wishing to bundle POV-Ray with commercial software or with publi-
 cations must first obtain explicit permission from the POV-Ray Team.  This
 includes any commercial software or publications, such as, but not limited
 to, magazines, books, newspapers, or newsletters in print or machine read-
 able form.

    The POV-Ray Team will decide if such distribution will be allowed on a
 case-by-case basis and may impose certain restrictions as it sees fit.  The
 minimum terms are given below.  Other conditions may be imposed.

            marked with a disclaimer that POV-Ray is free software and can be
            obtained for free or nominal cost from various sources.

            to pro-vide you or your customers any technical support.
       5)   Include a credit page or pages in your documentation for POV-Ray.
            If you modify any portion POV-Ray for use with your hardware or
            software, you must follow the custom version rules in addition to
            these rules.
       6)   Include contact and support information for your product.
       7)   Must include official documentation with product.

    Shareware and freeware distribution companies may distribute the archives
 under the conditions following this section.

    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. ($5.00) can be charged per disk for the
 copying of this software and the media it is provided on.  Space on each
 disk must used completely.  The company may not put each archive on a sepa-
 rate disk and charge for three disks if all three archives will fit on one
 disk.  If more than one disk is needed to store the archives then more than
 one disk may be used and charged for.

    Distribution on high volume media such as backup tape or CD-ROM is per-
 mitted if the total cost to the user is no more than $0.10 per megabyte of
 data.  For example a CD-ROM with 600 meg could cost no more than $60.00.

    On-line services and BBS's may distribute the POV-Ray archives under the
 conditions following this section.

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

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

    The on-line service or BBS may only charge standard usage rates for the
 downloading of this software.  A premium may not be charged for this pack-
 age.  For example: 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.  They must also make the all of the archives
 available in the same forum, so they can be easily located by a user.
