4812N/A Everyone is permitted to copy and distribute verbatim copies
4812N/A of this license document, but changing it is not allowed.
4812N/A[This is the first released version of the Lesser GPL. It also counts
4812N/A as the successor of the GNU Library Public License, version 2, hence
4812N/A The licenses for most software are designed to take away your
4812N/Afreedom to share and change it. By contrast, the GNU General Public
4812N/ALicenses are intended to guarantee your freedom to share and change
4812N/Afree software--to make sure the software is free for all its users.
4812N/A This license, the Lesser General Public License, applies to some
4812N/Aspecially designated software packages--typically libraries--of the
4812N/AFree Software Foundation and other authors who decide to use it. You
4812N/Acan use it too, but we suggest you first think carefully about whether
4812N/Athis license or the ordinary General Public License is the better
4812N/Astrategy to use in any particular case, based on the explanations
4812N/A When we speak of free software, we are referring to freedom of use,
4812N/Anot price. Our General Public Licenses are designed to make sure that
4812N/Ayou have the freedom to distribute copies of free software (and charge
4812N/Afor this service if you wish); that you receive source code or can get
4812N/Ait if you want it; that you can change the software and use pieces of
4812N/Ait in new free programs; and that you are informed that you can do
4812N/A To protect your rights, we need to make restrictions that forbid
4812N/Adistributors to deny you these rights or to ask you to surrender these
4812N/Arights. These restrictions translate to certain responsibilities for
4812N/Ayou if you distribute copies of the library or if you modify it.
4812N/A For example, if you distribute copies of the library, whether gratis
4812N/Aor for a fee, you must give the recipients all the rights that we gave
4812N/Ayou. You must make sure that they, too, receive or can get the source
4812N/Acode. If you link other code with the library, you must provide
4812N/Acomplete object files to the recipients, so that they can relink them
4812N/Awith the library after making changes to the library and recompiling
4812N/Ait. And you must show them these terms so they know their rights.
4812N/A We protect your rights with a two-step method: (1) we copyright the
4812N/Alibrary, and (2) we offer you this license, which gives you legal
4812N/A To protect each distributor, we want to make it very clear that
4812N/Athere is no warranty for the free library. Also, if the library is
4812N/Amodified by someone else and passed on, the recipients should know
4812N/Athat what they have is not the original version, so that the original
4812N/Aauthor's reputation will not be affected by problems that might be
4812N/A Finally, software patents pose a constant threat to the existence of
4812N/Aany free program. We wish to make sure that a company cannot
4812N/Aeffectively restrict the users of a free program by obtaining a
4812N/Arestrictive license from a patent holder. Therefore, we insist that
4812N/Aany patent license obtained for a version of the library must be
4812N/Aconsistent with the full freedom of use specified in this license.
4812N/A Most GNU software, including some libraries, is covered by the
4812N/Aordinary GNU General Public License. This license, the GNU Lesser
4812N/AGeneral Public License, applies to certain designated libraries, and
4812N/Ais quite different from the ordinary General Public License. We use
4812N/Athis license for certain libraries in order to permit linking those
4812N/Alibraries into non-free programs.
4812N/A When a program is linked with a library, whether statically or using
4812N/Aa shared library, the combination of the two is legally speaking a
4812N/Acombined work, a derivative of the original library. The ordinary
4812N/AGeneral Public License therefore permits such linking only if the
4812N/Aentire combination fits its criteria of freedom. The Lesser General
4812N/APublic License permits more lax criteria for linking other code with
4812N/A We call this license the "Lesser" General Public License because it
4812N/Adoes Less to protect the user's freedom than the ordinary General
4812N/APublic License. It also provides other free software developers Less
4812N/Aof an advantage over competing non-free programs. These disadvantages
4812N/Aare the reason we use the ordinary General Public License for many
4812N/Alibraries. However, the Lesser license provides advantages in certain
4812N/A For example, on rare occasions, there may be a special need to
4812N/Aencourage the widest possible use of a certain library, so that it
4812N/Abecomes a de-facto standard. To achieve this, non-free programs must
4812N/Abe allowed to use the library. A more frequent case is that a free
4812N/Alibrary does the same job as widely used non-free libraries. In this
4812N/Acase, there is little to gain by limiting the free library to free
4812N/Asoftware only, so we use the Lesser General Public License.
4812N/A In other cases, permission to use a particular library in non-free
4812N/Aprograms enables a greater number of people to use a large body of
4812N/Afree software. For example, permission to use the GNU C Library in
4812N/Anon-free programs enables many more people to use the whole GNU
4812N/A Although the Lesser General Public License is Less protective of the
4812N/Ausers' freedom, it does ensure that the user of a program that is
4812N/Alinked with the Library has the freedom and the wherewithal to run
4812N/Athat program using a modified version of the Library.
4812N/A The precise terms and conditions for copying, distribution and
4812N/Amodification follow. Pay close attention to the difference between a
4812N/A"work based on the library" and a "work that uses the library". The
4812N/Aformer contains code derived from the library, whereas the latter must
4812N/Abe combined with the library in order to run.
4812N/A GNU LESSER GENERAL PUBLIC LICENSE
4812N/A TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
4812N/A 0. This License Agreement applies to any software library or other
4812N/Aprogram which contains a notice placed by the copyright holder or
4812N/Aother authorized party saying it may be distributed under the terms of
4812N/Athis Lesser General Public License (also called "this License").
4812N/AEach licensee is addressed as "you".
4812N/A A "library" means a collection of software functions
and/or data
4812N/Aprepared so as to be conveniently linked with application programs
4812N/A(which use some of those functions and data) to form executables.
4812N/A The "Library", below, refers to any such software library or work
4812N/Awhich has been distributed under these terms. A "work based on the
4812N/ALibrary" means either the Library or any derivative work under
4812N/Acopyright law: that is to say, a work containing the Library or a
4812N/Aportion of it, either verbatim or with modifications
and/or translated
4812N/Astraightforwardly into another language. (Hereinafter, translation is
4812N/Aincluded without limitation in the term "modification".)
4812N/A "Source code" for a work means the preferred form of the work for
4812N/Amaking modifications to it. For a library, complete source code means
4812N/Aall the source code for all modules it contains, plus any associated
4812N/Ainterface definition files, plus the scripts used to control
4812N/Acompilation and installation of the library.
4812N/A Activities other than copying, distribution and modification are not
4812N/Acovered by this License; they are outside its scope. The act of
4812N/Arunning a program using the Library is not restricted, and output from
4812N/Asuch a program is covered only if its contents constitute a work based
4812N/Aon the Library (independent of the use of the Library in a tool for
4812N/Awriting it). Whether that is true depends on what the Library does
4812N/Aand what the program that uses the Library does.
4812N/A 1. You may copy and distribute verbatim copies of the Library's
4812N/Acomplete source code as you receive it, in any medium, provided that
4812N/Ayou conspicuously and appropriately publish on each copy an
4812N/Aappropriate copyright notice and disclaimer of warranty; keep intact
4812N/Aall the notices that refer to this License and to the absence of any
4812N/Awarranty; and distribute a copy of this License along with the
4812N/A You may charge a fee for the physical act of transferring a copy,
4812N/Aand you may at your option offer warranty protection in exchange for a
4812N/A 2. You may modify your copy or copies of the Library or any portion
4812N/Aof it, thus forming a work based on the Library, and copy and
4812N/Adistribute such modifications or work under the terms of Section 1
4812N/Aabove, provided that you also meet all of these conditions:
4812N/A a) The modified work must itself be a software library.
4812N/A b) You must cause the files modified to carry prominent notices
4812N/A stating that you changed the files and the date of any change.
4812N/A c) You must cause the whole of the work to be licensed at no
4812N/A charge to all third parties under the terms of this License.
4812N/A d) If a facility in the modified Library refers to a function or a
4812N/A table of data to be supplied by an application program that uses
4812N/A the facility, other than as an argument passed when the facility
4812N/A is invoked, then you must make a good faith effort to ensure that,
4812N/A in the event an application does not supply such function or
4812N/A table, the facility still operates, and performs whatever part of
4812N/A its purpose remains meaningful.
4812N/A (For example, a function in a library to compute square roots has
4812N/A a purpose that is entirely well-defined independent of the
4812N/A application. Therefore, Subsection 2d requires that any
4812N/A application-supplied function or table used by this function must
4812N/A be optional: if the application does not supply it, the square
4812N/A root function must still compute square roots.)
4812N/AThese requirements apply to the modified work as a whole. If
4812N/Aidentifiable sections of that work are not derived from the Library,
4812N/Aand can be reasonably considered independent and separate works in
4812N/Athemselves, then this License, and its terms, do not apply to those
4812N/Asections when you distribute them as separate works. But when you
4812N/Adistribute the same sections as part of a whole which is a work based
4812N/Aon the Library, the distribution of the whole must be on the terms of
4812N/Athis License, whose permissions for other licensees extend to the
4812N/Aentire whole, and thus to each and every part regardless of who wrote
4812N/AThus, it is not the intent of this section to claim rights or contest
4812N/Ayour rights to work written entirely by you; rather, the intent is to
4812N/Aexercise the right to control the distribution of derivative or
4812N/Acollective works based on the Library.
4812N/AIn addition, mere aggregation of another work not based on the Library
4812N/Awith the Library (or with a work based on the Library) on a volume of
4812N/Aa storage or distribution medium does not bring the other work under
4812N/A 3. You may opt to apply the terms of the ordinary GNU General Public
4812N/ALicense instead of this License to a given copy of the Library. To do
4812N/Athis, you must alter all the notices that refer to this License, so
4812N/Athat they refer to the ordinary GNU General Public License, version 2,
4812N/Ainstead of to this License. (If a newer version than version 2 of the
4812N/Aordinary GNU General Public License has appeared, then you can specify
4812N/Athat version instead if you wish.) Do not make any other change in
4812N/A Once this change is made in a given copy, it is irreversible for
4812N/Athat copy, so the ordinary GNU General Public License applies to all
4812N/Asubsequent copies and derivative works made from that copy.
4812N/A This option is useful when you wish to copy part of the code of
4812N/Athe Library into a program that is not a library.
4812N/A 4. You may copy and distribute the Library (or a portion or
4812N/Aderivative of it, under Section 2) in object code or executable form
4812N/Aunder the terms of Sections 1 and 2 above provided that you accompany
4812N/Ait with the complete corresponding machine-readable source code, which
4812N/Amust be distributed under the terms of Sections 1 and 2 above on a
4812N/Amedium customarily used for software interchange.
4812N/A If distribution of object code is made by offering access to copy
4812N/Afrom a designated place, then offering equivalent access to copy the
4812N/Asource code from the same place satisfies the requirement to
4812N/Adistribute the source code, even though third parties are not
4812N/Acompelled to copy the source along with the object code.
4812N/A 5. A program that contains no derivative of any portion of the
4812N/ALibrary, but is designed to work with the Library by being compiled or
4812N/Alinked with it, is called a "work that uses the Library". Such a
4812N/Awork, in isolation, is not a derivative work of the Library, and
4812N/Atherefore falls outside the scope of this License.
4812N/A However, linking a "work that uses the Library" with the Library
4812N/Acreates an executable that is a derivative of the Library (because it
4812N/Acontains portions of the Library), rather than a "work that uses the
4812N/Alibrary". The executable is therefore covered by this License.
4812N/ASection 6 states terms for distribution of such executables.
4812N/A When a "work that uses the Library" uses material from a header file
4812N/Athat is part of the Library, the object code for the work may be a
4812N/Aderivative work of the Library even though the source code is not.
4812N/AWhether this is true is especially significant if the work can be
4812N/Alinked without the Library, or if the work is itself a library. The
4812N/Athreshold for this to be true is not precisely defined by law.
4812N/A If such an object file uses only numerical parameters, data
4812N/Astructure layouts and accessors, and small macros and small inline
4812N/Afunctions (ten lines or less in length), then the use of the object
4812N/Afile is unrestricted, regardless of whether it is legally a derivative
4812N/Awork. (Executables containing this object code plus portions of the
4812N/ALibrary will still fall under Section 6.)
4812N/A Otherwise, if the work is a derivative of the Library, you may
4812N/Adistribute the object code for the work under the terms of Section 6.
4812N/AAny executables containing that work also fall under Section 6,
4812N/Awhether or not they are linked directly with the Library itself.
4812N/A 6. As an exception to the Sections above, you may also combine or
4812N/Alink a "work that uses the Library" with the Library to produce a
4812N/Awork containing portions of the Library, and distribute that work
4812N/Aunder terms of your choice, provided that the terms permit
4812N/Amodification of the work for the customer's own use and reverse
4812N/Aengineering for debugging such modifications.
4812N/A You must give prominent notice with each copy of the work that the
4812N/ALibrary is used in it and that the Library and its use are covered by
4812N/Athis License. You must supply a copy of this License. If the work
4812N/Aduring execution displays copyright notices, you must include the
4812N/Acopyright notice for the Library among them, as well as a reference
4812N/Adirecting the user to the copy of this License. Also, you must do one
4812N/A a) Accompany the work with the complete corresponding
4812N/A machine-readable source code for the Library including whatever
4812N/A changes were used in the work (which must be distributed under
4812N/A Sections 1 and 2 above); and, if the work is an executable linked
4812N/A with the Library, with the complete machine-readable "work that
4812N/A uses the Library", as object code
and/or source code, so that the
4812N/A user can modify the Library and then relink to produce a modified
4812N/A executable containing the modified Library. (It is understood
4812N/A that the user who changes the contents of definitions files in the
4812N/A Library will not necessarily be able to recompile the application
4812N/A to use the modified definitions.)
4812N/A b) Use a suitable shared library mechanism for linking with the
4812N/A Library. A suitable mechanism is one that (1) uses at run time a
4812N/A copy of the library already present on the user's computer system,
4812N/A rather than copying library functions into the executable, and (2)
4812N/A will operate properly with a modified version of the library, if
4812N/A the user installs one, as long as the modified version is
4812N/A interface-compatible with the version that the work was made with.
4812N/A c) Accompany the work with a written offer, valid for at least
4812N/A three years, to give the same user the materials specified in
4812N/A Subsection 6a, above, for a charge no more than the cost of
4812N/A performing this distribution.
4812N/A d) If distribution of the work is made by offering access to copy
4812N/A from a designated place, offer equivalent access to copy the above
4812N/A specified materials from the same place.
4812N/A e) Verify that the user has already received a copy of these
4812N/A materials or that you have already sent this user a copy.
4812N/A For an executable, the required form of the "work that uses the
4812N/ALibrary" must include any data and utility programs needed for
4812N/Areproducing the executable from it. However, as a special exception,
4812N/Athe materials to be distributed need not include anything that is
4812N/Anormally distributed (in either source or binary form) with the major
4812N/Acomponents (compiler, kernel, and so on) of the operating system on
4812N/Awhich the executable runs, unless that component itself accompanies
4812N/A It may happen that this requirement contradicts the license
4812N/Arestrictions of other proprietary libraries that do not normally
4812N/Aaccompany the operating system. Such a contradiction means you cannot
4812N/Ause both them and the Library together in an executable that you
4812N/A 7. You may place library facilities that are a work based on the
4812N/ALibrary side-by-side in a single library together with other library
4812N/Afacilities not covered by this License, and distribute such a combined
4812N/Alibrary, provided that the separate distribution of the work based on
4812N/Athe Library and of the other library facilities is otherwise
4812N/Apermitted, and provided that you do these two things:
4812N/A a) Accompany the combined library with a copy of the same work
4812N/A based on the Library, uncombined with any other library
4812N/A facilities. This must be distributed under the terms of the
4812N/A b) Give prominent notice with the combined library of the fact
4812N/A that part of it is a work based on the Library, and explaining
4812N/A where to find the accompanying uncombined form of the same work.
4812N/A 8. You may not copy, modify, sublicense, link with, or distribute
4812N/Athe Library except as expressly provided under this License. Any
4812N/Aattempt otherwise to copy, modify, sublicense, link with, or
4812N/Adistribute the Library is void, and will automatically terminate your
4812N/Arights under this License. However, parties who have received copies,
4812N/Aor rights, from you under this License will not have their licenses
4812N/Aterminated so long as such parties remain in full compliance.
4812N/A 9. You are not required to accept this License, since you have not
4812N/Asigned it. However, nothing else grants you permission to modify or
4812N/Adistribute the Library or its derivative works. These actions are
4812N/Aprohibited by law if you do not accept this License. Therefore, by
4812N/Amodifying or distributing the Library (or any work based on the
4812N/ALibrary), you indicate your acceptance of this License to do so, and
4812N/Aall its terms and conditions for copying, distributing or modifying
4812N/Athe Library or works based on it.
4812N/A 10. Each time you redistribute the Library (or any work based on the
4812N/ALibrary), the recipient automatically receives a license from the
4812N/Aoriginal licensor to copy, distribute, link with or modify the Library
4812N/Asubject to these terms and conditions. You may not impose any further
4812N/Arestrictions on the recipients' exercise of the rights granted herein.
4812N/AYou are not responsible for enforcing compliance by third parties with
4812N/A 11. If, as a consequence of a court judgment or allegation of patent
4812N/Ainfringement or for any other reason (not limited to patent issues),
4812N/Aconditions are imposed on you (whether by court order, agreement or
4812N/Aotherwise) that contradict the conditions of this License, they do not
4812N/Aexcuse you from the conditions of this License. If you cannot
4812N/Adistribute so as to satisfy simultaneously your obligations under this
4812N/ALicense and any other pertinent obligations, then as a consequence you
4812N/Amay not distribute the Library at all. For example, if a patent
4812N/Alicense would not permit royalty-free redistribution of the Library by
4812N/Aall those who receive copies directly or indirectly through you, then
4812N/Athe only way you could satisfy both it and this License would be to
4812N/Arefrain entirely from distribution of the Library.
4812N/AIf any portion of this section is held invalid or unenforceable under
4812N/Aany particular circumstance, the balance of the section is intended to
4812N/Aapply, and the section as a whole is intended to apply in other
4812N/AIt is not the purpose of this section to induce you to infringe any
4812N/Apatents or other property right claims or to contest validity of any
4812N/Asuch claims; this section has the sole purpose of protecting the
4812N/Aintegrity of the free software distribution system which is
4812N/Aimplemented by public license practices. Many people have made
4812N/Agenerous contributions to the wide range of software distributed
4812N/Athrough that system in reliance on consistent application of that
4812N/Ato distribute software through any other system and a licensee cannot
4812N/AThis section is intended to make thoroughly clear what is believed to
4812N/Abe a consequence of the rest of this License.
4812N/A 12. If the distribution
and/or use of the Library is restricted in
4812N/Acertain countries either by patents or by copyrighted interfaces, the
4812N/Aoriginal copyright holder who places the Library under this License
4812N/Amay add an explicit geographical distribution limitation excluding those
4812N/Acountries, so that distribution is permitted only in or among
4812N/Acountries not thus excluded. In such case, this License incorporates
4812N/Athe limitation as if written in the body of this License.
4812N/A 13. The Free Software Foundation may publish revised
and/or new
4812N/Aversions of the Lesser General Public License from time to time.
4812N/ASuch new versions will be similar in spirit to the present version,
4812N/Abut may differ in detail to address new problems or concerns.
4812N/AEach version is given a distinguishing version number. If the Library
4812N/Aspecifies a version number of this License which applies to it and
4812N/A"any later version", you have the option of following the terms and
4812N/Aconditions either of that version or of any later version published by
4812N/Athe Free Software Foundation. If the Library does not specify a
4812N/Alicense version number, you may choose any version ever published by
4812N/Athe Free Software Foundation.
4812N/A 14. If you wish to incorporate parts of the Library into other free
4812N/Aprograms whose distribution conditions are incompatible with these,
4812N/Awrite to the author to ask for permission. For software which is
4812N/Acopyrighted by the Free Software Foundation, write to the Free
4812N/ASoftware Foundation; we sometimes make exceptions for this. Our
4812N/Adecision will be guided by the two goals of preserving the free status
4812N/Aof all derivatives of our free software and of promoting the sharing
4812N/Aand reuse of software generally.
4812N/A 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
4812N/AWARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
4812N/AEXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR 4812N/AOTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
4812N/AKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
4812N/AIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
4812N/APURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
4812N/ALIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
4812N/ATHE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
4812N/A 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
4812N/AWRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
4812N/AAND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
4812N/AFOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
4812N/ACONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
4812N/ALIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

4812N/A How to Apply These Terms to Your New Libraries
4812N/A If you develop a new library, and you want it to be of the greatest
4812N/Apossible use to the public, we recommend making it free software that
4812N/Aeveryone can redistribute and change. You can do so by permitting
4812N/Aredistribution under these terms (or, alternatively, under the terms
4812N/Aof the ordinary General Public License).
4812N/A To apply these terms, attach the following notices to the library.
4812N/AIt is safest to attach them to the start of each source file to most
4812N/Aeffectively convey the exclusion of warranty; and each file should
4812N/Ahave at least the "copyright" line and a pointer to where the full

4812N/A Everyone is permitted to copy and distribute verbatim copies
4812N/A of this license document, but changing it is not allowed.
4812N/A The licenses for most software are designed to take away your
4812N/Afreedom to share and change it. By contrast, the GNU General Public
4812N/ALicense is intended to guarantee your freedom to share and change free
4812N/Asoftware--to make sure the software is free for all its users. This
4812N/AGeneral Public License applies to most of the Free Software
4812N/AFoundation's software and to any other program whose authors commit to
4812N/Ausing it. (Some other Free Software Foundation software is covered by
4812N/Athe GNU Lesser General Public License instead.) You can apply it to
4812N/A When we speak of free software, we are referring to freedom, not
4812N/Aprice. Our General Public Licenses are designed to make sure that you
4812N/Ahave the freedom to distribute copies of free software (and charge for
4812N/Athis service if you wish), that you receive source code or can get it
4812N/Aif you want it, that you can change the software or use pieces of it
4812N/Ain new free programs; and that you know you can do these things.
4812N/A To protect your rights, we need to make restrictions that forbid
4812N/Aanyone to deny you these rights or to ask you to surrender the rights.
4812N/AThese restrictions translate to certain responsibilities for you if you
4812N/Adistribute copies of the software, or if you modify it.
4812N/A For example, if you distribute copies of such a program, whether
4812N/Agratis or for a fee, you must give the recipients all the rights that
4812N/Ayou have. You must make sure that they, too, receive or can get the
4812N/Asource code. And you must show them these terms so they know their
4812N/A We protect your rights with two steps: (1) copyright the software, and
4812N/A(2) offer you this license which gives you legal permission to copy,
4812N/A Also, for each author's protection and ours, we want to make certain
4812N/Athat everyone understands that there is no warranty for this free
4812N/Asoftware. If the software is modified by someone else and passed on, we
4812N/Awant its recipients to know that what they have is not the original, so
4812N/Athat any problems introduced by others will not reflect on the original
4812N/A Finally, any free program is threatened constantly by software
4812N/Apatents. We wish to avoid the danger that redistributors of a free
4812N/Aprogram will individually obtain patent licenses, in effect making the
4812N/Aprogram proprietary. To prevent this, we have made it clear that any
4812N/Apatent must be licensed for everyone's free use or not licensed at all.
4812N/A The precise terms and conditions for copying, distribution and
4812N/A TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
4812N/A 0. This License applies to any program or other work which contains
4812N/Aa notice placed by the copyright holder saying it may be distributed
4812N/Aunder the terms of this General Public License. The "Program", below,
4812N/Arefers to any such program or work, and a "work based on the Program"
4812N/Ameans either the Program or any derivative work under copyright law:
4812N/Athat is to say, a work containing the Program or a portion of it,
4812N/Aeither verbatim or with modifications
and/or translated into another
4812N/Alanguage. (Hereinafter, translation is included without limitation in
4812N/Athe term "modification".) Each licensee is addressed as "you".
4812N/AActivities other than copying, distribution and modification are not
4812N/Acovered by this License; they are outside its scope. The act of
4812N/Arunning the Program is not restricted, and the output from the Program
4812N/Ais covered only if its contents constitute a work based on the
4812N/AProgram (independent of having been made by running the Program).
4812N/AWhether that is true depends on what the Program does.
4812N/A 1. You may copy and distribute verbatim copies of the Program's
4812N/Asource code as you receive it, in any medium, provided that you
4812N/Aconspicuously and appropriately publish on each copy an appropriate
4812N/Acopyright notice and disclaimer of warranty; keep intact all the
4812N/Anotices that refer to this License and to the absence of any warranty;
4812N/Aand give any other recipients of the Program a copy of this License
4812N/AYou may charge a fee for the physical act of transferring a copy, and
4812N/Ayou may at your option offer warranty protection in exchange for a fee.
4812N/A 2. You may modify your copy or copies of the Program or any portion
4812N/Aof it, thus forming a work based on the Program, and copy and
4812N/Adistribute such modifications or work under the terms of Section 1
4812N/Aabove, provided that you also meet all of these conditions:
4812N/A a) You must cause the modified files to carry prominent notices
4812N/A stating that you changed the files and the date of any change.
4812N/A b) You must cause any work that you distribute or publish, that in
4812N/A whole or in part contains or is derived from the Program or any
4812N/A part thereof, to be licensed as a whole at no charge to all third
4812N/A parties under the terms of this License.
4812N/A c) If the modified program normally reads commands interactively
4812N/A when run, you must cause it, when started running for such
4812N/A interactive use in the most ordinary way, to print or display an
4812N/A announcement including an appropriate copyright notice and a
4812N/A notice that there is no warranty (or else, saying that you provide
4812N/A a warranty) and that users may redistribute the program under
4812N/A these conditions, and telling the user how to view a copy of this
4812N/A License. (Exception: if the Program itself is interactive but
4812N/A does not normally print such an announcement, your work based on
4812N/A the Program is not required to print an announcement.)
4812N/AThese requirements apply to the modified work as a whole. If
4812N/Aidentifiable sections of that work are not derived from the Program,
4812N/Aand can be reasonably considered independent and separate works in
4812N/Athemselves, then this License, and its terms, do not apply to those
4812N/Asections when you distribute them as separate works. But when you
4812N/Adistribute the same sections as part of a whole which is a work based
4812N/Aon the Program, the distribution of the whole must be on the terms of
4812N/Athis License, whose permissions for other licensees extend to the
4812N/Aentire whole, and thus to each and every part regardless of who wrote it.
4812N/AThus, it is not the intent of this section to claim rights or contest
4812N/Ayour rights to work written entirely by you; rather, the intent is to
4812N/Aexercise the right to control the distribution of derivative or
4812N/Acollective works based on the Program.
4812N/AIn addition, mere aggregation of another work not based on the Program
4812N/Awith the Program (or with a work based on the Program) on a volume of
4812N/Aa storage or distribution medium does not bring the other work under
4812N/A 3. You may copy and distribute the Program (or a work based on it,
4812N/Aunder Section 2) in object code or executable form under the terms of
4812N/ASections 1 and 2 above provided that you also do one of the following:
4812N/A a) Accompany it with the complete corresponding machine-readable
4812N/A source code, which must be distributed under the terms of Sections
4812N/A 1 and 2 above on a medium customarily used for software interchange; or,
4812N/A b) Accompany it with a written offer, valid for at least three
4812N/A years, to give any third party, for a charge no more than your
4812N/A cost of physically performing source distribution, a complete
4812N/A machine-readable copy of the corresponding source code, to be
4812N/A distributed under the terms of Sections 1 and 2 above on a medium
4812N/A customarily used for software interchange; or,
4812N/A c) Accompany it with the information you received as to the offer
4812N/A to distribute corresponding source code. (This alternative is
4812N/A allowed only for noncommercial distribution and only if you
4812N/A received the program in object code or executable form with such
4812N/A an offer, in accord with Subsection b above.)
4812N/AThe source code for a work means the preferred form of the work for
4812N/Amaking modifications to it. For an executable work, complete source
4812N/Acode means all the source code for all modules it contains, plus any
4812N/Aassociated interface definition files, plus the scripts used to
4812N/Acontrol compilation and installation of the executable. However, as a
4812N/Aspecial exception, the source code distributed need not include
4812N/Aanything that is normally distributed (in either source or binary
4812N/Aform) with the major components (compiler, kernel, and so on) of the
4812N/Aoperating system on which the executable runs, unless that component
4812N/Aitself accompanies the executable.
4812N/AIf distribution of executable or object code is made by offering
4812N/Aaccess to copy from a designated place, then offering equivalent
4812N/Aaccess to copy the source code from the same place counts as
4812N/Adistribution of the source code, even though third parties are not
4812N/Acompelled to copy the source along with the object code.
4812N/A 4. You may not copy, modify, sublicense, or distribute the Program
4812N/Aexcept as expressly provided under this License. Any attempt
4812N/Aotherwise to copy, modify, sublicense or distribute the Program is
4812N/Avoid, and will automatically terminate your rights under this License.
4812N/AHowever, parties who have received copies, or rights, from you under
4812N/Athis License will not have their licenses terminated so long as such
4812N/Aparties remain in full compliance.
4812N/A 5. You are not required to accept this License, since you have not
4812N/Asigned it. However, nothing else grants you permission to modify or
4812N/Adistribute the Program or its derivative works. These actions are
4812N/Aprohibited by law if you do not accept this License. Therefore, by
4812N/Amodifying or distributing the Program (or any work based on the
4812N/AProgram), you indicate your acceptance of this License to do so, and
4812N/Aall its terms and conditions for copying, distributing or modifying
4812N/Athe Program or works based on it.
4812N/A 6. Each time you redistribute the Program (or any work based on the
4812N/AProgram), the recipient automatically receives a license from the
4812N/Aoriginal licensor to copy, distribute or modify the Program subject to
4812N/Athese terms and conditions. You may not impose any further
4812N/Arestrictions on the recipients' exercise of the rights granted herein.
4812N/AYou are not responsible for enforcing compliance by third parties to
4812N/A 7. If, as a consequence of a court judgment or allegation of patent
4812N/Ainfringement or for any other reason (not limited to patent issues),
4812N/Aconditions are imposed on you (whether by court order, agreement or
4812N/Aotherwise) that contradict the conditions of this License, they do not
4812N/Aexcuse you from the conditions of this License. If you cannot
4812N/Adistribute so as to satisfy simultaneously your obligations under this
4812N/ALicense and any other pertinent obligations, then as a consequence you
4812N/Amay not distribute the Program at all. For example, if a patent
4812N/Alicense would not permit royalty-free redistribution of the Program by
4812N/Aall those who receive copies directly or indirectly through you, then
4812N/Athe only way you could satisfy both it and this License would be to
4812N/Arefrain entirely from distribution of the Program.
4812N/AIf any portion of this section is held invalid or unenforceable under
4812N/Aany particular circumstance, the balance of the section is intended to
4812N/Aapply and the section as a whole is intended to apply in other
4812N/AIt is not the purpose of this section to induce you to infringe any
4812N/Apatents or other property right claims or to contest validity of any
4812N/Asuch claims; this section has the sole purpose of protecting the
4812N/Aintegrity of the free software distribution system, which is
4812N/Aimplemented by public license practices. Many people have made
4812N/Agenerous contributions to the wide range of software distributed
4812N/Athrough that system in reliance on consistent application of that
4812N/Ato distribute software through any other system and a licensee cannot
4812N/AThis section is intended to make thoroughly clear what is believed to
4812N/Abe a consequence of the rest of this License.
4812N/A 8. If the distribution
and/or use of the Program is restricted in
4812N/Acertain countries either by patents or by copyrighted interfaces, the
4812N/Aoriginal copyright holder who places the Program under this License
4812N/Amay add an explicit geographical distribution limitation excluding
4812N/Athose countries, so that distribution is permitted only in or among
4812N/Acountries not thus excluded. In such case, this License incorporates
4812N/Athe limitation as if written in the body of this License.
4812N/A 9. The Free Software Foundation may publish revised
and/or new versions
4812N/Aof the General Public License from time to time. Such new versions will
4812N/Abe similar in spirit to the present version, but may differ in detail to
4812N/Aaddress new problems or concerns.
4812N/AEach version is given a distinguishing version number. If the Program
4812N/Aspecifies a version number of this License which applies to it and "any
4812N/Alater version", you have the option of following the terms and conditions
4812N/Aeither of that version or of any later version published by the Free
4812N/ASoftware Foundation. If the Program does not specify a version number of
4812N/Athis License, you may choose any version ever published by the Free Software
4812N/A 10. If you wish to incorporate parts of the Program into other free
4812N/Aprograms whose distribution conditions are different, write to the author
4812N/Ato ask for permission. For software which is copyrighted by the Free
4812N/ASoftware Foundation, write to the Free Software Foundation; we sometimes
4812N/Amake exceptions for this. Our decision will be guided by the two goals
4812N/Aof preserving the free status of all derivatives of our free software and
4812N/Aof promoting the sharing and reuse of software generally.
4812N/A 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
4812N/AFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
4812N/AOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES
4812N/APROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
4812N/AOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
4812N/AMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
4812N/ATO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
4812N/APROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
4812N/A 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
4812N/AWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR 4812N/AREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
4812N/AINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
4812N/AOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
4812N/ATO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
4812N/AYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
4812N/APROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
4812N/APOSSIBILITY OF SUCH DAMAGES.
4812N/A END OF TERMS AND CONDITIONS
4812N/A How to Apply These Terms to Your New Programs
4812N/A If you develop a new program, and you want it to be of the greatest
4812N/Apossible use to the public, the best way to achieve this is to make it
4812N/Afree software which everyone can redistribute and change under these terms.
4812N/A To do so, attach the following notices to the program. It is safest
4812N/Ato attach them to the start of each source file to most effectively
4812N/Aconvey the exclusion of warranty; and each file should have at least
4812N/Athe "copyright" line and a pointer to where the full notice is found.
4812N/A <one line to give the program's name and a brief idea of what it does.>
4812N/A Copyright (C) <year> <name of author>
4812N/A This program is free software; you can redistribute it
and/or modify
4812N/A it under the terms of the GNU General Public License as published by

4812N/A (at your option) any later version.
4812N/A This program is distributed in the hope that it will be useful,
4812N/A but WITHOUT ANY WARRANTY; without even the implied warranty of
4812N/A MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
4812N/A GNU General Public License for more details.
4812N/A You should have received a copy of the GNU General Public License along
4812N/A with this program; if not, write to the Free Software Foundation, Inc.,
4812N/A 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
4812N/AAlso add information on how to contact you by electronic and paper mail.
4812N/AIf the program is interactive, make it output a short notice like this
4812N/Awhen it starts in an interactive mode:
4812N/A Gnomovision version 69, Copyright (C) year name of author
4812N/A Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
4812N/A This is free software, and you are welcome to redistribute it
4812N/A under certain conditions; type `show c' for details.
4812N/AThe hypothetical commands `show w' and `show c' should show the appropriate
4812N/Aparts of the General Public License. Of course, the commands you use may
4812N/Abe called something other than `show w' and `show c'; they could even be
4812N/Amouse-clicks or menu items--whatever suits your program.
4812N/AYou should also get your employer (if you work as a programmer) or your
4812N/Aschool, if any, to sign a "copyright disclaimer" for the program, if
4812N/Anecessary. Here is a sample; alter the names:

4812N/AThis General Public License does not permit incorporating your program into
4812N/Aproprietary programs. If your program is a subroutine library, you may
4812N/Aconsider it more useful to permit linking proprietary applications with the
4812N/Alibrary. If this is what you want to do, use the GNU Lesser General
4812N/APublic License instead of this License.
