-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. 
-
-COPYRIGHT

-flowing from your unauthorized use of the Software.
-
-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

-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).
