+
+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
+
+Copyright ©, POV-Team[tm] 1991-2002. Copyright subsists in the Software
+which is protected by Australian and international copyright laws.
+Although it is distributed as freeware, it is NOT PUBLIC DOMAIN. You
+acknowledge that any and all intellectual property rights including
+all rights of copyright used or embodied in or in connection with the
+Software are and will remain the sole property of the POV-Team[tm]. You
+shall not question or dispute the ownership of such rights at any
+time. Nothing in this document shall give you any rights in respect
+of the intellectual property of the POV-Team[tm] and you acknowledge
+that you do not acquire any rights in respect of such intellectual
+property rights. If you use, modify or distribute the Software for
+unauthorized purposes or in an unauthorized manner, you will be
+liable to the POV-Team[tm] for any damages it may suffer (and which you
+acknowledge it may suffer) and you may also be liable to criminal
+prosecution. You indemnify the POV-Team[tm] for every single consequence
+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
+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).
