INTRODUCTION

This document pertains to the  use and distribution of the Persistence
of Vision[tm] Ray Tracer a.k.a  POV-Ray[tm] and known in this document
as  POV-Ray[tm] or  'the Software'.   It applies  to all  POV- Ray[tm]
program  source   files,  executable  (binary)   files,  scene  files,
documentation  files, help file,  bitmaps and  INI files  contained in
official POV-Team[tm] archives.  All of  these are referred to here as
"the Software".  The POV-Team[tm] reserves  the right to  revise these
rules in future  versions and to make additional  rules to address new
circumstances at any time. Such rules,  when made, will be posted in a
revised POVLEGAL.DOC,  the latest version  of which is  available from
our website  at http://www.povray.org/povlegal.html.  The POV-Team[tm]
are the programmers and assistants from  time to time who work as part
of the "POV-Team" in the development, modification and/or distribution
of the Software.

INTENT OF THIS LICENSE

The intent of this license is to allow the free and legal distribution
of POV-Ray[tm] throughout the community, and to permit users to freely
enjoy its benefits. The POV-Ray[tm] developers, past and present, have
donated their time and in some cases considerable amounts of their own
money  towards the  development  of this  software  package, which  we
provide for no charge (within  the constraints of this license) to the
public at large.

The POV-Ray[tm]  developers decided, long ago (about  1990), that they
did  not  want the  free  nature  of this  package  to  be sullied  by
unscrupulous third  parties who wanted to  make a quick  buck from the
developer's  hard work. This  decision was  made after  some practical
experience  with just  such activity.   We have  strong  objections to
end-users  having  to pay  for  this  software  when they  could  have
received it for free had they only known better.

Though  this may  seem  an unlikely  scenario  for those  used to  the
internet and  aware of the  free availability of POV-Ray[tm],  this in
fact does to this day still happen.  As this updated POVLEGAL is being
written (in  2001) there is at  least one CD  that we know of  - being
sold  both on  the  internet and  in  stores -  that  is presented  to
potential purchasers  as a 3D rendering product,  with nothing present
on the exterior that would lead the buyer to believe that the renderer
inside is in fact a free program (namely, POV-Ray[tm]).

Therefore,  the   intent  of  this   license  is  to   encourage  free
distribution and use, while severely restricting non-free distribution
and  use.   Some  of  the  more  wordy  sections  below  dealing  with
third-party distribution  have only become so  because some commercial
vendors found some fairly imaginative ways to avoid the intent of this
license. If your  intended use of the Software  seems to conflict with
this basic intent,  you should contact us before  proceeding with your
plans (but read the rest of this document before you write).

WHY ISN'T POV-RAY OPEN SOURCE ?

While this explanation doesn't really  belong in this document, we are
asked it often enough that we  have decided to put it here.  While the
POV-Ray[tm] source code is freely available, it isn't 'open' according
to the currently popular definition of the term (meaning that it isn't
available  to  create derivative  works).  The  reasons  for this  are
historical.  Primarily,  at the  time that POV-Ray[tm]  was originally
developed (starting in about 1990),  on Compuserve, it was a different
environment than today. Virtually  none of the developers had internet
access and there wasn't a great awareness of things like the GPL.  The
team at that time rolled their own license - one that allowed free use
of  the  software  but  attempted  to  prevent  people  taking  unfair
advantage of it.

As people contributed  code to POV-Ray[tm] over the  years - and there
have been  many instances of this -  they contributed it to  us on the
understanding that it would be  covered by the POV-Ray[tm] license, as
it stood  at the time.  Now, in  2001, we find  that in many  cases we
don't know  who wrote  what part of  the code,  or that the  author is
uncontactable. We  simply don't have  the right to  arbitrarily change
the terms under  which their source code is  distributed.  Even though
it was contributed  to us, we feel that we must  honor the terms under
which  it was  given.  Therefore,  POV- Ray[tm]  will  remain on  this
existing license  until we do a  full re-write (which  is intended for
v4), at which  time a new license will be instituted  that is far more
liberal in terms of reuse.

DISCLAIMER OF WARRANTY

This Software is provided on an "AS IS" basis, without warranty of any
kind, express  or implied,  including without limitation,  the implied
warranties of  merchantability, fitness  for a particular  purpose and
non-infringement  of intellectual  property of  any third  party. This
Software  has   inherent  limitations  including   design  faults  and
programming bugs.  As  the program is free, the entire  risk as to the
quality and  performance of the  Software is borne  by you, and  it is
your responsibility  to ensure that it  does what you intend  it to do
prior to using  it for any purpose other than  testing it.  Should the
Software  prove defective,  you  and not  the  POV-Team[tm] or  anyone
associated with them assume the entire cost of any service and repair.
This disclaimer of warranty constitutes an essential and material term
of this agreement.

NO LIABILITY AND INDEMNITY

When you use the Software you acknowledge and accept that you do so at
your sole risk.  You agree  that under no circumstances shall you have
any claim  against the POV-Team[tm]  or anyone associated  directly or
indirectly with  the POV-Team[tm] whether  as employee, subcontractor,
agent,    representative,    consultant,    licensee   or    otherwise
("POV-Team[tm]  associates")  for  any  loss, damages,  harm,  injury,
expense,  work  stoppage,   loss  of  business  information,  business
interruption, computer failure or malfunction which may be suffered by
you  or  by any  third  party  from  any cause  whatsoever,  howsoever
arising,  in  connection with  your  use  and/or  distribution of  the
Software even where the POV-Team[tm] were aware, or ought to have been
aware, of the  potential of such loss.  Damages  shall include direct,
indirect, general, special, incidental, punitive and/or consequential.
If you  do not accept  this no liability  condition, you must  not use
this Software.

You  indemnify the  POV-Team[tm] and  the POV-Team[tm]  associates and
hold them harmless  against any claims which may  arise from any loss,
damages,  harm,  injury,  expense,  work stoppage,  loss  of  business
information, business  interruption, computer failure  or malfunction,
which may  be suffered  by you, your  spouse, dependants or  any other
third party whatsoever as a consequence  of any act or omission of the
POV-Team[tm] and/or the  POV-Team[tm] associates, whether negligent or
not, arising out  of your use and/or distribution  of the Software, or
from any other cause  whatsoever, howsoever arising in connection with
the  Software.  These provisions  are binding  on your  estate, heirs,
executors, administrators, parents and/or guardians.

HIGH RISK ACTIVITIES

This  Software  and  the  output  produced by  this  Software  is  not
fault-tolerant and  is not designed, manufactured or  intended for use
or  resale  as on-line  control  equipment  in hazardous  environments
requiring fail-safe performance, in  which the failure of the Software
could lead directly  to death, personal injury, or  severe physical or
environmental   damage  ("High   Risk   Activities").   The   POV-Team
specifically disclaim  any express or implied warranty  of fitness for
High Risk Activities.

USAGE PROVISIONS

Subject to the terms and  conditions of this agreement, 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 retains all rights to the scene file they created, and any  image
generated by the Software from them. 

The user  is also  granted the  right to  use the  scene files, fonts,
bitmaps,  and   include  files   distributed  in   the  INCLUDE    and
SCENES\INCDEMO sub-directories  in their  own scenes.  Such permission
does not  extend to  any other  files in  the SCENES  directory or its
sub-directories.  The  SCENES  files   are  for  your  enjoyment   and
education but may not be the basis of any derivative works unless  the
file in question explicitly grants permission to do such.

ACCEPTANCE OF LICENSE

Some jurisdictions deem licenses that have not been physically  signed
by the person or legal entity using the software which is the  subject
of the license to  have not been accepted  in a legal sense.  However,
since you  have not  paid for  this Software,  nothing else other than
acceptance  of  this  license  in  full  grants  you the right to use,
modify, or  distribute it  or any  derivative works  made from  it. By
using, modifying, making  a derivative work, or distributing any  part
or  version  of  the  Software,  you  indicate your acceptance of this
License and all of its terms and conditions. If you have not  accepted
the license such actions would be illegal.

DISTRIBUTION AND/OR MODIFICATION

This  copyrighted  package  may  ONLY  be  distributed and/or modified
according  to  the  terms  and  conditions  contained  in this License
Agreement.  

The  permission  to  distribute  this  Software,  under  certain  very
specific  conditions,  is  granted  in  advance,  provided  that   the
following  conditions  are  met.  If  your  distribution,  or intended
distribution, does not meet  these conditions, you may  not distribute
the Software. 

Anyone  intending to distribute  this Software  must ensure  that they
comply  with  our license  at  all times.   If  you  are intending  to
distribute POV-Ray[tm]  and are  not reading the  master copy  of this
license found on  our web site at http://www.povray.org/povlegal.html,
you should instead read that version, as it may have changed since the
copy that you are reading was written.

The   Software   must   not   be   distributed   commercially   (where
'commercially'  means any  distribution that  would qualify  under the
terms  of  the  'CONDITIONS  FOR COMMERCIAL  BUNDLING'  section  which
appears later in this document) without the express written permission
of the POV-Team.   This restriction applies not only  to this Software
but also to any derivative of it or any part of it.

You may not distribute (or continue to distribute if you have  already
started) the Software if you have been or are in breach of any of  the
conditions of this  license, or if  you or your  legal representatives
have  been  notified  by  us  or  our  authorized representatives (via
telephone, email,  fax, or  physical mail  to the  last known  contact
point for that communication method) that you may not. 

The  Software must not  be distributed  in a  form different  from the
official distribution  without the express,  prior, written permission
of  the POV-Team[tm].   The official  distribution are  those official
versions  which appear  on our  website from  time to  time.   You may
rename the distribution  files only to meet the  file name conventions
of your system  or to avoid file name  duplications.  The POV-Team[tm]
is willing to make exceptions in certain circumstances (e.g.  to allow
Linux  vendors to use  RPM), but  these are  on a  case-by-case basis.
Please write us if you would like to do this.

You  must  distribute  a  FULL  PACKAGE  of  files  as  defined  under
"DEFINITION OF FULL  PACKAGE" below, 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. 

Any physical  distribution (that  is, by any  means other  than online
download)  of  POV-Ray[tm] by  any  person  or  organisation, for  any
purpose other than personal sharing of the software, must include full
contact details of the distributor.  This includes at the very least a
valid physical mailing address (including country), a telephone number
if the distributor provides that for  any of its other products, and a
working,  manned email  address  if the  distributor  has an  internet
presence of any  sort. If the distributor has a web  site then its URL
must also be included.

Only 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.  No  other restrictions may be placed  on the
distribution of the Software.  

Internet distribution of our official archives on web or FTP sites  is
permitted,  provided  that  no  charge  is  made  for  downloading  or
accessing  the  files  (other  than  the  normal fees the user pays to
access  the  internet),  and  that  the  versions  distributed are the
latest  available  (or  that,  in  the  case  of a web page, a clearly
positioned link is provided to the latest version, and in the case  of
an  FTP  site,  that  the  latest  version  is  present  in  the  same
subdirectory). 

Teachers  and  educational  institutions   may  also  distribute   the
material  to  students  for  free  or  they may charge minimal copying
costs if the Software is to be used in a course. 

Any other distribution  for which money  or any other  compensation is
asked  for  or  received  must  meet  the terms and conditions set out
below. 

CONDITIONS FOR CD-ROM DISTRIBUTION
CONDITIONS FOR SHAREWARE/FREEWARE DISTRIBUTION

A  'shareware  and  freeware  distributor',  for  the  purpose of this
document, is  one which  CLEARLY IDENTIFIES  itself as  such to anyone
dealing  with  it  or  its  resellers,  both in general, and also with
respect to  the interior  and exterior  packaging of  any products  it
sells. If there is  any possibility that a  person, prior to or  after
performing a purchase  of any shareware  or freeware product  from the
distributor or  any reseller  of the  distributor, would  not be aware
that  they  are  receiving  shareware  or freeware software, then that
distributor is  NOT considered  a 'shareware  or freeware distributor'
by this license, and the following grant of permission does not  apply
to them. 

Additionally, the following only  applies to distributors of collected
programs;  anyone  wishing to  bundle  the  package  with a  shareware
product must  use the  commercial bundling rules  set out  below under
"CONDITIONS FOR COMMERCIAL BUNDLING".  Also, a distribution that would
otherwise  have qualified  under the  'shareware/freeware distributor'
terms, but  which is  constructed in such  a way  that it would  be of
little  or  no  practical   use  without  POV-Ray[tm],  is  considered
commercial and must use the commercial bundling rules.

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. 

Distribution on CD-ROM or high  capacity media such as backup  tape is
permitted if the total cost to the  user is no more than two (2)  U.S.
cents per megabyte of  data. For example a  CD-ROM with 600 meg  could
cost no more than US$12.00 at  any point of sale, including the  point
of sale to the consumer.  Companies or individuals that distribute  to
resellers hereby agree that they will be in breach of this license  if
any  of  their  resellers  breach  this  license and such companies or
individuals indemnify the POV-Team[tm] accordingly. 

Any bundling with books, magazines  or other print media must have the
prior written approval of the  POV-Team[tm].  If we do approve of such
publication,  you  must  provide  us   with  two  (2)  copies  of  the
publication in  question as  soon as  it is released.  In the  case of
magazines,  we   normally  approve  such  requests,   subject  to  the
conditions in this document.

For floppy  disk distribution,  no more  than one  US dollar (US$1.00)
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. 

The users to whom you wish  to distribute the Software must also agree
to be  bound by  the terms and  conditions of this  License Agreement.
You  indemnify the POV-Team[tm]  from any  loss or  harm which  it may
suffer as  a result of your failure  to ensure that the  users to whom
you are distributing the Software have agreed to be bound by the terms
and conditions of this License Agreement.

ONLINE OR REMOTE EXECUTION OF POV-RAY

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

Users  must be prominently  informed that  they are  using POV-Ray[tm]
software, that such software is free, and where they can find official
POV-Ray[tm] software. Any attempt to obscure the fact that the user is
running POV-Ray[tm] is expressly prohibited.

All  files   normally  available  in  a   full  package  distribution,
especially  a copy  of this  license  and full  documentation must  be
available for download  or readable online so that  users of an online
executable have access to all of  the material of a full user package.
The full user package is  the entire distribution for a given platform
excluding the  actual program files. The distributor  must also ensure
that the users have agreed to  be bound by the terms and conditions of
this license, failing which such users may not download or view or use
the Software.

If the POV-Ray[tm] software has been modified in any way, it must also
comply  with  the  provisions   for  custom  versions  set  out  under
"CONDITIONS FOR DISTRIBUTION OF CUSTOM VERSIONS" below.

DEFINITION OF "FULL PACKAGE"

A "full  package" contains  an executable  program, documentation, and
sample scenes. For  generic Unix platforms,  there are no  executables
available  so  the  source  code  must  be  included  instead  of  the
executable program, unless you choose to build one (in which case  you
must comply with the terms for unofficial versions, found below). 

POV-Ray[tm] is officially distributed  for Windows 95/98/NT; Linux for
Intel x86  series; and Apple PowerPC.   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 CD-ROM need not distribute the Windows versions. 

This  Software  may  ONLY  be  bundled  with  other  software packages
according  to   the  conditions   specified  under   "CONDITIONS   FOR
COMMERCIAL BUNDLING" below. 

PERMITTED MODIFICATION AND CUSTOM VERSIONS

Although the  full source code  for POV-Ray[tm] is  distributed, there
are  strict  rules  for  the  use  of  the  source  code.  The  source
distribution is provided to; 1)  promote the porting of POV-Ray[tm] to
hardware and operating systems  which the POV-Team[tm] cannot support,
2) promote experimentation and development of new features to the core
code which might eventually be incorporated into the official version,
and  3) provide insight  into the  inner workings  of the  program for
educational purposes.

These license  provisions have been established to  promote the growth
of  POV-Ray[tm]  and prevent  difficulties  for  users and  developers
alike.  Please follow them carefully  for the benefit of all concerned
when creating a custom version.

The user  is granted  the privilege  to modify  and compile the source
code for their own personal use in any fashion they see fit. 

However strict  conditions and  restrictions are  imposed if  the user
wishes   to   distribute   a   modified   version   of  the  Software,
documentation or other parts of the package (hereafter referred to  as
a  "custom   version").  This   includes  any   translation  of    the
documentation into other languages or other file formats. 

A  "custom  version" is  defined  as  a  fully functional  version  of
POV-Ray[tm]  with  all existing  features,  copyright notices,  author
attributions, this  License Agreement, etc., intact. ANY  OTHER USE OF
ANY POV-RAY SOURCE CODE IS EXPRESSLY PROHIBITED. The POV-Team[tm] does
not license source  code for any use outside  POV-Ray[tm].  No portion
of  the  POV-Ray[tm] source  code  may  be,  under any  circumstances,
incorporated  into  another program  unless  it  is  clearly a  custom
version  of POV-Ray[tm]  that includes  all  of the  functions of  the
POV-Ray[tm] renderer.

All executables, documentation, modified files and descriptions of the
same  must clearly identify  themselves as  a modified  and unofficial
version of POV-Ray[tm]. Any attempt  to obscure the fact that the user
is running POV-Ray[tm] or to  obscure that it is an unofficial version
is expressly prohibited.

POV-Ray[tm]  may   not  be  linked  into  other   software  either  at
compile-time using  an object  code linker nor  at run-time as  a DLL,
ActiveX,  or other system.   Such linkage  can tend  to blur  the end-
user's perception  of which program provides which  functions and thus
qualifies as an attempt to obscure what is running.

To  allow  POV-Ray[tm]  to  communicate  with  outside  programs,  the
official  versions of POV-Ray[tm]  may include  internal communication
"hooks"  for it  to  call  other tasks,  often  called an  Application
Programming  Interface,  or API.  For  example:  the  generic part  of
POV-Ray[tm]  provides  operating system  shell-out  API commands.  The
Windows version has a GUI-extension API and the ability to replace the
text editor.  Modification to these APIs or other officially supported
communication mechanisms to increase  functionality beyond that of the
official version, or to avoid the intent of this license, is EXPRESSLY
PROHIBITED.

CONDITIONS FOR DISTRIBUTION OF CUSTOM VERSIONS

If  your  re-compiled  version  meets  all  requirements  for   custom
versions  listed  above  under  "PERMITTED  MODIFICATION  AND   CUSTOM
VERSIONS",  the   following  additional   conditions  apply   to   its
distribution: 

You  must  provide all  support  for all  users  who  use your  custom
version. You  must provide information  so that users may  contact you
for  support for  your custom  version.  The  POV-Ray[tm] Team  is not
obligated to provide you or your users any technical support.

You  must  include  contact  information  in  the DISTRIBUTION_MESSAGE
macros  in  the  source  file  OPTOUT.H  and  insure  that the program
prominently  displays  this  information.  You  must  ensure that your
version  displays  all  copyright  notices  and credit screens for the
official version, though they must be clearly marked as unofficial.   

The  purpose  of  this  next  requirement is  to  allow  the  official
POV-Ray[tm] to  detect scene  files that are  incompatible with  it by
testing the  #version declaration. It can  then tell the  user why the
given  scene file  will  not work,  rather  than issue  what could  be
confusing syntax  errors or perform erroneous  rendering. This results
in a better experience for the end users of this Software.

If  your  custom version  contains  any  feature  that would  cause  a
POV-Ray[tm] scene  source file that works  on your version  to fail or
otherwise work  incorrectly on either the current  official version of
POV-Ray[tm],  or on  the  official  version that  was  built from  the
version of the source that you  are using for your custom version, you
must  include  code that  checks  that the  scene  source  file has  a
#version directive that includes  the 'unofficial' token, and you must
only  activate  your  changes  (including,  but not  limited  to,  new
keywords) if that #version directive is present.  If it is not present
your  custom  version  must work  in  the  same  way as  the  standard
POV-Ray[tm]  that  it  is  built   from.   An  example  of  a  correct
'unofficial'  #version  declaration  is '#version  unofficial  megapov
0.7;'.

Custom versions may only be distributed as freeware and under terms no
less  restrictive  than this  license.   You  must  make all  of  your
modifications to  POV-Ray[tm] freely and publicly  available with FULL
SOURCE CODE  to the modified  portions of POV-Ray[tm] and  must freely
distribute full  source to  any new parts  of the custom  version. The
goal is that  users must be able to  re-compile the program themselves
using  readily available compilers  and run-time  libraries and  to be
able to further improve the program with their own modifications.

You must provide documentation for any and all modifications that  you
have made to the program  that you are distributing and  include clear
and obvious information on how to obtain the official POV-Ray[tm]. 

The  user is  encouraged to  send enhancements  and bug  fixes  to the
POV-Team[tm],  but the team  is in  no way  required to  utilize these
enhancements  or  fixes.   By   sending  material  to  the  team,  the
contributor asserts and warrants that he owns the materials or has the
right to  distribute these materials.   He authorizes the team  to use
the materials any way they  like. The contributor still retains rights
to the donated material, but by donating, grants, and warrants that he
is entitled to grant  unrestricted, irrevocable usage and distribution
rights to the POV-Team[tm] and  indemnifies them against any claims of
unauthorized use  of the donated software or  any technology contained
or expressed within it. The team doesn't have to use the material, but
if it does, you do not  acquire any rights related to POV-Ray[tm]. The
team may give you credit as the creator of new code if applicable.

You must  include a  copy of  the latest  version of  this document as
obtained  from  http://www.povray.org/povlegal.html,  and  ensure that
the user has agreed to be bound by the terms and conditions of use  as
set out in this  License Agreement.  You  indemnify the POV- Team  for
any harm or loss which they may suffer as a result of your failure  to
do so.

CONDITIONS FOR COMMERCIAL BUNDLING

Vendors wishing to bundle POV-Ray[tm] (or any software that is derived
from  it  or any  part  of  it)  with commercial  software  (including
shareware)  or any  other use  or distribution  not  already expressly
allowed above  must first obtain  express written permission  from the
POV-Team[tm]. The POV-Team[tm] will, in its sole discretion, decide if
such  Use will  be  allowed on  a  case-by-case basis  and may  impose
whatever conditions it sees fit.

For commercial distribution, the minimum terms are given below.  Other
conditions may be imposed.

The  product must be  an existing  product that  has proven  itself as
commercially viable without  POV-Ray[tm] included, unless the POV-Team
expressly grants exception  to this rule. Such exceptions  will not be
granted  unless it  can be  demonstrated that  POV-Ray or  the POV-Ray
community would somehow benefit from allowing such an exception.

The inclusion of  POV-Ray[tm] should be promoted only  as a free bonus
and not  as a feature designed  to encourage customers  to purchase or
upgrade solely for the POV-Ray[tm] capability.

Purchasers of  your product must not  be led to believe  that they are
paying for POV-Ray[tm].  Any mention  of the POV-Ray[tm] bundle on the
box, in advertising  or in instruction manuals must  be clearly marked
with  a  disclaimer that  POV-Ray[tm]  is  free  software and  can  be
obtained for free or nominal cost from various sources.

You  must  include  clear  and  obvious  information  on how to obtain
POV-Ray[tm] via our official distribution points.

You must  provide all POV-Ray[tm]  support for all users  who acquired
POV-Ray[tm] through  your product.  The POV-Team[tm]  is not obligated
to provide you or your customers any technical support.

You must  include a  credit page  or pages  in your  documentation for
POV-Ray[tm].

If you modify any portion of POV-Ray[tm] for use with your hardware or
software,  you must  follow the  custom version  rules in  addition to
these rules.

You must include contact and support information for your product.

You  must  include  a  full  user  package  as described in "ONLINE OR
REMOTE EXECUTION OF POV-RAY"  above , including the  License Agreement
which the user must agree to be bound by.

POV-TEAM ENDORSEMENT PROHIBITION

On rare  occasions, the  POV-Team[tm] endorses distributions  in which
POV-Team[tm]  members are  compensated participants  and to  which the
POV-Team[tm] has given approval.

Without specific  approval, distributors (whether  free or commercial)
must not  claim or imply in  any way that  the POV-Team[tm] officially
endorses or supports the distributor or the product (such as CD, book,
or magazine) associated with the distribution.

You may not  claim or imply that the  POV-Team[tm] derives any benefit
from your distribution.

If you wish to emphasize that  your distribution is legal, you may use
this  language   "This  distribution   of  the  official   version  of
POV-Ray[tm] is permitted under the terms of the General License in the
file POVLEGAL.DOC.  The POV-Team[tm] does not  endorse the distributor
or its  products.  The POV-Team[tm] receives no  compensation for this
distribution."

RETAIL VALUE OF THIS SOFTWARE

Although  POV-Ray[tm] is, when  distributed within  the terms  of this
agreement, free of charge, the retail value (or price) of this program
is  determined as  US$30.00 per  copy distributed  or copied.   If the
Software is distributed or  copied without authorization the person(s)
or entity(ies) responsible or involved  are each legally liable to the
maximum extent  permitted by law for  the full amount of  this debt to
the copyright holder, or any other person or organization delegated by
the copyright holder for the collection of this debt.

However,  the  above  paragraph  in  no  way constitutes permission to
distribute this Software  outside of the  terms of this  agreement. In
particular, the conditions and  debt mentioned above (whether  paid or
unpaid) do  not allow  you to  avoid statutory  damages or other legal
penalties and does not constitute  any agreement that would allow  you
to avoid such other legal  remedies as are available to  the copyright
holder. 

Put  simply,  POV-Ray[tm]  is  only   free  if  you  comply  with  our
distribution  conditions; it  is  not free  otherwise.  The  copyright
holder of this  Software chooses to give it away  free under these and
only these  conditions.  If you distribute this  Software in violation
of this license, what you are doing is no different than if you took a
copy of a  commercial software product and distributed  it without the
permission of the copyright holder of that product.

For  the  purpose  of  copyright  regulations and/or statutory damages
provisions, the retail value of this Software is US$30.00 per copy. 

USE OF THE POV-RAY SCENE LANGUAGE

The team  permits and encourages  the creation of  programs, including
commercial packages,  which import, export  or translate files  in the
POV-Ray[tm] Scene Description Language.  Subject to the requirement in
the following paragraph,  there are no restrictions on  the use of the
language itself (this does not include  the source code that we use to
implement the language).

The POV-Team[tm]  reserves the  right to add  or remove or  change any
part of the language.  Prior  to using the POV-Ray[tm] scene language,
you  agree  that  you  will  not  hold  the  POV-Team[tm],  or  anyone
associated with it,  or the contributor or author  or initiator of any
such change,  in any  way responsible for  whatever happens to  you or
your product, program, or whatever  use you put the scene language to,
as a  direct or indirect  result of any  such change or  changes. This
explicitly includes,  but is not  limited to, any  lost compatibility,
lost  profits,  bugs,  extra  development or  maintenance,  public  or
private embarrassment or public relations problems.  Your attention is
drawn to the  "NO LIABILITY AND INDEMNITY "  provisions above to which
you agree to be bound.

TRADEMARKS

"POV-Ray[tm]", "Persistence of  Vision", "POV-Team[tm]" and "POV-Help"
are trademarks of the  POV-Team[tm].  Any other trademarks referred to
herein are the property of their respective holders. You undertake not
to use, apply for, or register  anywhere in the world, any word, name,
trade mark  or device which is substantially  identical or deceptively
or confusingly similar to any of the POV- Team's[tm] trade marks.

REVOCATION OF LICENSE

VIOLATION OF THIS  LICENSE IS A  VIOLATION OF COPYRIGHT  LAWS. IT WILL
RESULT IN REVOCATION  OF ALL PRIVILEGES  GRANTED BY IT  AND MAY RESULT
IN CIVIL OR CRIMINAL LIABILITY . 

Violators who are prohibited from  distribution may from time to  time
be identified in this document. 

In  this regard,  "PC Format",  a magazine  published at  the  time by
Future Publishing, Ltd. in  the United Kingdom, distributed incomplete
versions of POV-Ray[tm]  1.0 in violation of the  license which was in
effect at the time. They later attempted to distribute POV-Ray[tm] 2.2
without  prior permission  of  the POV-Team[tm]  in  violation of  the
license which  was in effect at  the time. After  the POV-Team[tm] was
made  aware of  their intent,  they  were contacted  and were  granted
permission   in  return   for  certain   promises  they   made.   They
subsequently failed to honor these promises.

There is  evidence that  other Future  Publishing companies  have also
violated our terms. PC  Format's actions, particularly in  relation to
the incomplete  v1.0 distribution  (which simply  didn't work properly
due to  files that  had been  deleted to  fit on  the magazine's cover
floppy  disk  -  causing  many  users  to  blame us for the faults and
complain  to  us  in  email)  caused  us  un-needed stress and support
headaches. 

Therefore "PC  Format", and any  other magazine, book, CD-ROM,  or any
other type of publication owned in whole or part by, or related in any
other  way, to  Future  Publishing is  expressly  prohibited from  any
distribution of POV-Ray[tm] software.

MISCELLANEOUS

This  Agreement  constitutes the  complete  agreement concerning  this
license.  Any  changes to  this agreement must  be in writing  and may
take the form of notifications  by the POV-Team[tm] to you, or through
posting notifications on our website.  The use of this Software by any
person is expressly made conditional  on their acceptance of the terms
set forth  herein. If any provision  of this Agreement is  found to be
invalid or  unenforceable, the invalidity or  unenforceability of such
provision shall not affect the  other provisions of this agreement and
all  provisions not  affected by  such invalidity  or unenforceability
shall  remain in  full  force and  effect.   You agree  to attempt  to
substitute  for   invalid  or  unenforceable  provision   a  valid  or
enforceable provision which achieves  to the greatest extent possible,
the  objectives   and  intention  of  the   invalid  or  unenforceable
provision. The  validity and interpretation of this  agreement will be
governed by the laws of Australia in the state of Victoria (except for
conflict of law provisions).
