	<h2 class="heading"> Preamble </h2>

	<p> The licenses for most software are designed to take away your
	freedom to share and change it. By contrast, the GNU General Public
	License is intended to guarantee your freedom to share and change free
	software—to make sure the software is free for all its users. This
	General Public License applies to most of the Free Software
	Foundation's software and to any other program whose authors commit to
	using it. (Some other Free Software Foundation software is covered by
	the GNU Lesser General Public License instead.) You can apply it to
	your programs, too.
	</p>
	<p> When we speak of free software, we are referring to freedom, not
	price. Our General Public Licenses are designed to make sure that you
	have the freedom to distribute copies of free software (and charge for
	this service if you wish), that you receive source code or can get it
	if you want it, that you can change the software or use pieces of it
	in new free programs; and that you know you can do these things.
	</p>
	<p> To protect your rights, we need to make restrictions that forbid
	anyone to deny you these rights or to ask you to surrender the rights.
	These restrictions translate to certain responsibilities for you if you
	distribute copies of the software, or if you modify it.
	</p>
	<p> For example, if you distribute copies of such a program, whether
	gratis or for a fee, you must give the recipients all the rights that
	you have. You must make sure that they, too, receive or can get the
	source code. And you must show them these terms so they know their
	rights.
	</p>
	<p> We protect your rights with two steps: (1) copyright the software, and
	(2) offer you this license which gives you legal permission to copy,
	distribute and/or modify the software.
	</p>
	<p> Also, for each author's protection and ours, we want to make certain
	that everyone understands that there is no warranty for this free
	software. If the software is modified by someone else and passed on, we
	want its recipients to know that what they have is not the original, so
	that any problems introduced by others will not reflect on the original
	authors' reputations.
	</p>
	<p> Finally, any free program is threatened constantly by software
	patents. We wish to avoid the danger that redistributors of a free
	program will individually obtain patent licenses, in effect making the
	program proprietary. To prevent this, we have made it clear that any
	patent must be licensed for everyone's free use or not licensed at all.
	</p>
	<p> The precise terms and conditions for copying, distribution and
	modification follow.
	</p>
	<a name="SEC378"></a>
	<h2 class="heading"> TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION </h2>

	<ol>
	<li>
	This License applies to any program or other work which contains
	a notice placed by the copyright holder saying it may be distributed
	under the terms of this General Public License. The “Program”, below,
	refers to any such program or work, and a “work based on the Program”
	means either the Program or any derivative work under copyright law:
	that is to say, a work containing the Program or a portion of it,
	either verbatim or with modifications and/or translated into another
	language. (Hereinafter, translation is included without limitation in
	the term “modification”.) Each licensee is addressed as “you”.

	<p>Activities other than copying, distribution and modification are not
	covered by this License; they are outside its scope. The act of
	running the Program is not restricted, and the output from the Program
	is covered only if its contents constitute a work based on the
	Program (independent of having been made by running the Program).
	Whether that is true depends on what the Program does.
	</p>
	</li><li>
	You may copy and distribute verbatim copies of the Program's
	source code as you receive it, in any medium, provided that you
	conspicuously and appropriately publish on each copy an appropriate
	copyright notice and disclaimer of warranty; keep intact all the
	notices that refer to this License and to the absence of any warranty;
	and give any other recipients of the Program a copy of this License
	along with the Program.

	<p>You may charge a fee for the physical act of transferring a copy, and
	you may at your option offer warranty protection in exchange for a fee.
	</p>
	</li><li>
	You may modify your copy or copies of the Program or any portion
	of it, thus forming a work based on the Program, and copy and
	distribute such modifications or work under the terms of Section 1
	above, provided that you also meet all of these conditions:

	<ol>
	<li>
	You must cause the modified files to carry prominent notices
	stating that you changed the files and the date of any change.

	</li><li>
	You must cause any work that you distribute or publish, that in
	whole or in part contains or is derived from the Program or any
	part thereof, to be licensed as a whole at no charge to all third
	parties under the terms of this License.

	</li><li>
	If the modified program normally reads commands interactively
	when run, you must cause it, when started running for such
	interactive use in the most ordinary way, to print or display an
	announcement including an appropriate copyright notice and a
	notice that there is no warranty (or else, saying that you provide
	a warranty) and that users may redistribute the program under
	these conditions, and telling the user how to view a copy of this
	License. (Exception: if the Program itself is interactive but
	does not normally print such an announcement, your work based on
	the Program is not required to print an announcement.)
	</li></ol>

	<p>These requirements apply to the modified work as a whole. If
	identifiable sections of that work are not derived from the Program,
	and can be reasonably considered independent and separate works in
	themselves, then this License, and its terms, do not apply to those
	sections when you distribute them as separate works. But when you
	distribute the same sections as part of a whole which is a work based
	on the Program, the distribution of the whole must be on the terms of
	this License, whose permissions for other licensees extend to the
	entire whole, and thus to each and every part regardless of who wrote it.
	</p>
	<p>Thus, it is not the intent of this section to claim rights or contest
	your rights to work written entirely by you; rather, the intent is to
	exercise the right to control the distribution of derivative or
	collective works based on the Program.
	</p>
	<p>In addition, mere aggregation of another work not based on the Program
	with the Program (or with a work based on the Program) on a volume of
	a storage or distribution medium does not bring the other work under
	the scope of this License.
	</p>
	</li><li>
	You may copy and distribute the Program (or a work based on it,
	under Section 2) in object code or executable form under the terms of
	Sections 1 and 2 above provided that you also do one of the following:

	<ol>
	<li>
	Accompany it with the complete corresponding machine-readable
	source code, which must be distributed under the terms of Sections
	1 and 2 above on a medium customarily used for software interchange; or,

	</li><li>
	Accompany it with a written offer, valid for at least three
	years, to give any third party, for a charge no more than your
	cost of physically performing source distribution, a complete
	machine-readable copy of the corresponding source code, to be
	distributed under the terms of Sections 1 and 2 above on a medium
	customarily used for software interchange; or,

	</li><li>
	Accompany it with the information you received as to the offer
	to distribute corresponding source code. (This alternative is
	allowed only for noncommercial distribution and only if you
	received the program in object code or executable form with such
	an offer, in accord with Subsection b above.)
	</li></ol>

	<p>The source code for a work means the preferred form of the work for
	making modifications to it. For an executable work, complete source
	code means all the source code for all modules it contains, plus any
	associated interface definition files, plus the scripts used to
	control compilation and installation of the executable. However, as a
	special exception, the source code distributed need not include
	anything that is normally distributed (in either source or binary
	form) with the major components (compiler, kernel, and so on) of the
	operating system on which the executable runs, unless that component
	itself accompanies the executable.
	</p>
	<p>If distribution of executable or object code is made by offering
	access to copy from a designated place, then offering equivalent
	access to copy the source code from the same place counts as
	distribution of the source code, even though third parties are not
	compelled to copy the source along with the object code.
	</p>
	</li><li>
	You may not copy, modify, sublicense, or distribute the Program
	except as expressly provided under this License. Any attempt
	otherwise to copy, modify, sublicense or distribute the Program is
	void, and will automatically terminate your rights under this License.
	However, parties who have received copies, or rights, from you under
	this License will not have their licenses terminated so long as such
	parties remain in full compliance.

	</li><li>
	You are not required to accept this License, since you have not
	signed it. However, nothing else grants you permission to modify or
	distribute the Program or its derivative works. These actions are
	prohibited by law if you do not accept this License. Therefore, by
	modifying or distributing the Program (or any work based on the
	Program), you indicate your acceptance of this License to do so, and
	all its terms and conditions for copying, distributing or modifying
	the Program or works based on it.

	</li><li>
	Each time you redistribute the Program (or any work based on the
	Program), the recipient automatically receives a license from the
	original licensor to copy, distribute or modify the Program subject to
	these terms and conditions. You may not impose any further
	restrictions on the recipients' exercise of the rights granted herein.
	You are not responsible for enforcing compliance by third parties to
	this License.

	</li><li>
	If, as a consequence of a court judgment or allegation of patent
	infringement or for any other reason (not limited to patent issues),
	conditions are imposed on you (whether by court order, agreement or
	otherwise) that contradict the conditions of this License, they do not
	excuse you from the conditions of this License. If you cannot
	distribute so as to satisfy simultaneously your obligations under this
	License and any other pertinent obligations, then as a consequence you
	may not distribute the Program at all. For example, if a patent
	license would not permit royalty-free redistribution of the Program by
	all those who receive copies directly or indirectly through you, then
	the only way you could satisfy both it and this License would be to
	refrain entirely from distribution of the Program.

	<p>If any portion of this section is held invalid or unenforceable under
	any particular circumstance, the balance of the section is intended to
	apply and the section as a whole is intended to apply in other
	circumstances.
	</p>
	<p>It is not the purpose of this section to induce you to infringe any
	patents or other property right claims or to contest validity of any
	such claims; this section has the sole purpose of protecting the
	integrity of the free software distribution system, which is
	implemented by public license practices. Many people have made
	generous contributions to the wide range of software distributed
	through that system in reliance on consistent application of that
	system; it is up to the author/donor to decide if he or she is willing
	to distribute software through any other system and a licensee cannot
	impose that choice.
	</p>
	<p>This section is intended to make thoroughly clear what is believed to
	be a consequence of the rest of this License.
	</p>
	</li><li>
	If the distribution and/or use of the Program is restricted in
	certain countries either by patents or by copyrighted interfaces, the
	original copyright holder who places the Program under this License
	may add an explicit geographical distribution limitation excluding
	those countries, so that distribution is permitted only in or among
	countries not thus excluded. In such case, this License incorporates
	the limitation as if written in the body of this License.

	</li><li>
	The Free Software Foundation may publish revised and/or new versions
	of the General Public License from time to time. Such new versions will
	be similar in spirit to the present version, but may differ in detail to
	address new problems or concerns.

	<p>Each version is given a distinguishing version number. If the Program
	specifies a version number of this License which applies to it and “any
	later version”, you have the option of following the terms and conditions
	either of that version or of any later version published by the Free
	Software Foundation. If the Program does not specify a version number of
	this License, you may choose any version ever published by the Free Software
	Foundation.
	</p>
	</li><li>
	If you wish to incorporate parts of the Program into other free
	programs whose distribution conditions are different, write to the author
	to ask for permission. For software which is copyrighted by the Free
	Software Foundation, write to the Free Software Foundation; we sometimes
	make exceptions for this. Our decision will be guided by the two goals
	of preserving the free status of all derivatives of our free software and
	of promoting the sharing and reuse of software generally.


	</li><li>
	BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
	FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
	OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
	PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
	OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
	MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
	TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
	PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
	REPAIR OR CORRECTION.

	</li><li>
	IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
	REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
	INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
	OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
	TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
	YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
	PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
	POSSIBILITY OF SUCH DAMAGES.
	</li></ol>

	<h2 class="heading"> Appendix: How to Apply These Terms to Your New Programs </h2>

	<p> If you develop a new program, and you want it to be of the greatest
	possible use to the public, the best way to achieve this is to make it
	free software which everyone can redistribute and change under these terms.
	</p>
	<p> To do so, attach the following notices to the program. It is safest
	to attach them to the start of each source file to most effectively
	convey the exclusion of warranty; and each file should have at least
	the “copyright” line and a pointer to where the full notice is found.
	</p>
	<table><tr><td> </td><td><pre class="smallexample"><var>one line to give the program's name and a brief idea of what it does.</var>
	Copyright (C) <var>yyyy</var> <var>name of author</var>

	This program is free software; you can redistribute it and/or modify
	it under the terms of the GNU General Public License as published by
	the Free Software Foundation; either version 2 of the License, or
	(at your option) any later version.

	This program is distributed in the hope that it will be useful,
	but WITHOUT ANY WARRANTY; without even the implied warranty of
	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
	GNU General Public License for more details.

	You should have received a copy of the GNU General Public License
	along with this program; if not, write to the Free Software
	Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
	</pre></td></tr></table>

	<p>Also add information on how to contact you by electronic and paper mail.
	</p>
	<p>If the program is interactive, make it output a short notice like this
	when it starts in an interactive mode:
	</p>
	<table><tr><td> </td><td><pre class="smallexample">Gnomovision version 69, Copyright (C) <var>year</var> <var>name of author</var>
	Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
	This is free software, and you are welcome to redistribute it
	under certain conditions; type `show c' for details.
	</pre></td></tr></table>

	<p>The hypothetical commands ‘<samp>show w</samp>’ and ‘<samp>show c</samp>’ should show
	the appropriate parts of the General Public License. Of course, the
	commands you use may be called something other than ‘<samp>show w</samp>’ and
	‘<samp>show c</samp>’; they could even be mouse-clicks or menu items—whatever
	suits your program.
	</p>
	<p>You should also get your employer (if you work as a programmer) or your
	school, if any, to sign a “copyright disclaimer” for the program, if
	necessary. Here is a sample; alter the names:
	</p>
	<table><tr><td> </td><td><pre class="example">Yoyodyne, Inc., hereby disclaims all copyright interest in the program

	Ty Coon, President of Vice
	</pre></td></tr></table>

	<p>This General Public License does not permit incorporating your program into
	proprietary programs. If your program is a subroutine library, you may
	consider it more useful to permit linking proprietary applications with the
	library. If this is what you want to do, use the GNU Lesser General
	Public License instead of this License.

	<h3 class="subheading"> Preamble </h3>

	<p> The licenses for most software are designed to take away your
	freedom to share and change it. By contrast, the GNU General Public
	Licenses are intended to guarantee your freedom to share and change
	free software—to make sure the software is free for all its users.
	</p>
	<p> This license, the Lesser General Public License, applies to some
	specially designated software—typically libraries—of the Free
	Software Foundation and other authors who decide to use it. You can use
	it too, but we suggest you first think carefully about whether this
	license or the ordinary General Public License is the better strategy to
	use in any particular case, based on the explanations below.
	</p>
	<p> When we speak of free software, we are referring to freedom of use,
	not price. Our General Public Licenses are designed to make sure that
	you have the freedom to distribute copies of free software (and charge
	for this service if you wish); that you receive source code or can get
	it if you want it; that you can change the software and use pieces of it
	in new free programs; and that you are informed that you can do these
	things.
	</p>
	<p> To protect your rights, we need to make restrictions that forbid
	distributors to deny you these rights or to ask you to surrender these
	rights. These restrictions translate to certain responsibilities for
	you if you distribute copies of the library or if you modify it.
	</p>
	<p> For example, if you distribute copies of the library, whether gratis
	or for a fee, you must give the recipients all the rights that we gave
	you. You must make sure that they, too, receive or can get the source
	code. If you link other code with the library, you must provide
	complete object files to the recipients, so that they can relink them
	with the library after making changes to the library and recompiling
	it. And you must show them these terms so they know their rights.
	</p>
	<p> We protect your rights with a two-step method: (1) we copyright the
	library, and (2) we offer you this license, which gives you legal
	permission to copy, distribute and/or modify the library.
	</p>
	<p> To protect each distributor, we want to make it very clear that
	there is no warranty for the free library. Also, if the library is
	modified by someone else and passed on, the recipients should know
	that what they have is not the original version, so that the original
	author's reputation will not be affected by problems that might be
	introduced by others.
	</p>
	<p> Finally, software patents pose a constant threat to the existence of
	any free program. We wish to make sure that a company cannot
	effectively restrict the users of a free program by obtaining a
	restrictive license from a patent holder. Therefore, we insist that
	any patent license obtained for a version of the library must be
	consistent with the full freedom of use specified in this license.
	</p>
	<p> Most GNU software, including some libraries, is covered by the
	ordinary GNU General Public License. This license, the GNU Lesser
	General Public License, applies to certain designated libraries, and
	is quite different from the ordinary General Public License. We use
	this license for certain libraries in order to permit linking those
	libraries into non-free programs.
	</p>
	<p> When a program is linked with a library, whether statically or using
	a shared library, the combination of the two is legally speaking a
	combined work, a derivative of the original library. The ordinary
	General Public License therefore permits such linking only if the
	entire combination fits its criteria of freedom. The Lesser General
	Public License permits more lax criteria for linking other code with
	the library.
	</p>
	<p> We call this license the <em>Lesser</em> General Public License because it
	does <em>Less</em> to protect the user's freedom than the ordinary General
	Public License. It also provides other free software developers Less
	of an advantage over competing non-free programs. These disadvantages
	are the reason we use the ordinary General Public License for many
	libraries. However, the Lesser license provides advantages in certain
	special circumstances.
	</p>
	<p> For example, on rare occasions, there may be a special need to
	encourage the widest possible use of a certain library, so that it becomes
	a de-facto standard. To achieve this, non-free programs must be
	allowed to use the library. A more frequent case is that a free
	library does the same job as widely used non-free libraries. In this
	case, there is little to gain by limiting the free library to free
	software only, so we use the Lesser General Public License.
	</p>
	<p> In other cases, permission to use a particular library in non-free
	programs enables a greater number of people to use a large body of
	free software. For example, permission to use the GNU C Library in
	non-free programs enables many more people to use the whole GNU
	operating system, as well as its variant, the GNU/Linux operating
	system.
	</p>
	<p> Although the Lesser General Public License is Less protective of the
	users' freedom, it does ensure that the user of a program that is
	linked with the Library has the freedom and the wherewithal to run
	that program using a modified version of the Library.
	</p>
	<p> The precise terms and conditions for copying, distribution and
	modification follow. Pay close attention to the difference between a
	“work based on the library” and a “work that uses the library”. The
	former contains code derived from the library, whereas the latter must
	be combined with the library in order to run.

	<h3 class="subheading"> TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION </h3>

	<ol>
	<li>
	This License Agreement applies to any software library or other program
	which contains a notice placed by the copyright holder or other
	authorized party saying it may be distributed under the terms of this
	Lesser General Public License (also called “this License”). Each
	licensee is addressed as “you”.

	<p> A “library” means a collection of software functions and/or data
	prepared so as to be conveniently linked with application programs
	(which use some of those functions and data) to form executables.
	</p>
	<p> The “Library”, below, refers to any such software library or work
	which has been distributed under these terms. A “work based on the
	Library” means either the Library or any derivative work under
	copyright law: that is to say, a work containing the Library or a
	portion of it, either verbatim or with modifications and/or translated
	straightforwardly into another language. (Hereinafter, translation is
	included without limitation in the term “modification”.)
	</p>
	<p> “Source code” for a work means the preferred form of the work for
	making modifications to it. For a library, complete source code means
	all the source code for all modules it contains, plus any associated
	interface definition files, plus the scripts used to control compilation
	and installation of the library.
	</p>
	<p> Activities other than copying, distribution and modification are not
	covered by this License; they are outside its scope. The act of
	running a program using the Library is not restricted, and output from
	such a program is covered only if its contents constitute a work based
	on the Library (independent of the use of the Library in a tool for
	writing it). Whether that is true depends on what the Library does
	and what the program that uses the Library does.
	</p>
	</li><li>
	You may copy and distribute verbatim copies of the Library's
	complete source code as you receive it, in any medium, provided that
	you conspicuously and appropriately publish on each copy an
	appropriate copyright notice and disclaimer of warranty; keep intact
	all the notices that refer to this License and to the absence of any
	warranty; and distribute a copy of this License along with the
	Library.

	<p> You may charge a fee for the physical act of transferring a copy,
	and you may at your option offer warranty protection in exchange for a
	fee.
	</p>
	</li><li>
	You may modify your copy or copies of the Library or any portion
	of it, thus forming a work based on the Library, and copy and
	distribute such modifications or work under the terms of Section 1
	above, provided that you also meet all of these conditions:

	<ol>
	<li>
	The modified work must itself be a software library.

	</li><li>
	You must cause the files modified to carry prominent notices
	stating that you changed the files and the date of any change.

	</li><li>
	You must cause the whole of the work to be licensed at no
	charge to all third parties under the terms of this License.

	</li><li>
	If a facility in the modified Library refers to a function or a
	table of data to be supplied by an application program that uses
	the facility, other than as an argument passed when the facility
	is invoked, then you must make a good faith effort to ensure that,
	in the event an application does not supply such function or
	table, the facility still operates, and performs whatever part of
	its purpose remains meaningful.

	<p>(For example, a function in a library to compute square roots has
	a purpose that is entirely well-defined independent of the
	application. Therefore, Subsection 2d requires that any
	application-supplied function or table used by this function must
	be optional: if the application does not supply it, the square
	root function must still compute square roots.)
	</p></li></ol>

	<p>These requirements apply to the modified work as a whole. If
	identifiable sections of that work are not derived from the Library,
	and can be reasonably considered independent and separate works in
	themselves, then this License, and its terms, do not apply to those
	sections when you distribute them as separate works. But when you
	distribute the same sections as part of a whole which is a work based
	on the Library, the distribution of the whole must be on the terms of
	this License, whose permissions for other licensees extend to the
	entire whole, and thus to each and every part regardless of who wrote
	it.
	</p>
	<p>Thus, it is not the intent of this section to claim rights or contest
	your rights to work written entirely by you; rather, the intent is to
	exercise the right to control the distribution of derivative or
	collective works based on the Library.
	</p>
	<p>In addition, mere aggregation of another work not based on the Library
	with the Library (or with a work based on the Library) on a volume of
	a storage or distribution medium does not bring the other work under
	the scope of this License.
	</p>
	</li><li>
	You may opt to apply the terms of the ordinary GNU General Public
	License instead of this License to a given copy of the Library. To do
	this, you must alter all the notices that refer to this License, so
	that they refer to the ordinary GNU General Public License, version 2,
	instead of to this License. (If a newer version than version 2 of the
	ordinary GNU General Public License has appeared, then you can specify
	that version instead if you wish.) Do not make any other change in
	these notices.

	<p> Once this change is made in a given copy, it is irreversible for
	that copy, so the ordinary GNU General Public License applies to all
	subsequent copies and derivative works made from that copy.
	</p>
	<p> This option is useful when you wish to copy part of the code of
	the Library into a program that is not a library.
	</p>
	</li><li>
	You may copy and distribute the Library (or a portion or
	derivative of it, under Section 2) in object code or executable form
	under the terms of Sections 1 and 2 above provided that you accompany
	it with the complete corresponding machine-readable source code, which
	must be distributed under the terms of Sections 1 and 2 above on a
	medium customarily used for software interchange.

	<p> If distribution of object code is made by offering access to copy
	from a designated place, then offering equivalent access to copy the
	source code from the same place satisfies the requirement to
	distribute the source code, even though third parties are not
	compelled to copy the source along with the object code.
	</p>
	</li><li>
	A program that contains no derivative of any portion of the
	Library, but is designed to work with the Library by being compiled or
	linked with it, is called a “work that uses the Library”. Such a
	work, in isolation, is not a derivative work of the Library, and
	therefore falls outside the scope of this License.

	<p> However, linking a “work that uses the Library” with the Library
	creates an executable that is a derivative of the Library (because it
	contains portions of the Library), rather than a “work that uses the
	library”. The executable is therefore covered by this License.
	Section 6 states terms for distribution of such executables.
	</p>
	<p> When a “work that uses the Library” uses material from a header file
	that is part of the Library, the object code for the work may be a
	derivative work of the Library even though the source code is not.
	Whether this is true is especially significant if the work can be
	linked without the Library, or if the work is itself a library. The
	threshold for this to be true is not precisely defined by law.
	</p>
	<p> If such an object file uses only numerical parameters, data
	structure layouts and accessors, and small macros and small inline
	functions (ten lines or less in length), then the use of the object
	file is unrestricted, regardless of whether it is legally a derivative
	work. (Executables containing this object code plus portions of the
	Library will still fall under Section 6.)
	</p>
	<p> Otherwise, if the work is a derivative of the Library, you may
	distribute the object code for the work under the terms of Section 6.
	Any executables containing that work also fall under Section 6,
	whether or not they are linked directly with the Library itself.
	</p>
	</li><li>
	As an exception to the Sections above, you may also combine or
	link a “work that uses the Library” with the Library to produce a
	work containing portions of the Library, and distribute that work
	under terms of your choice, provided that the terms permit
	modification of the work for the customer's own use and reverse
	engineering for debugging such modifications.

	<p> You must give prominent notice with each copy of the work that the
	Library is used in it and that the Library and its use are covered by
	this License. You must supply a copy of this License. If the work
	during execution displays copyright notices, you must include the
	copyright notice for the Library among them, as well as a reference
	directing the user to the copy of this License. Also, you must do one
	of these things:
	</p>
	<ol>
	<li>
	Accompany the work with the complete corresponding
	machine-readable source code for the Library including whatever
	changes were used in the work (which must be distributed under
	Sections 1 and 2 above); and, if the work is an executable linked
	with the Library, with the complete machine-readable “work that
	uses the Library”, as object code and/or source code, so that the
	user can modify the Library and then relink to produce a modified
	executable containing the modified Library. (It is understood
	that the user who changes the contents of definitions files in the
	Library will not necessarily be able to recompile the application
	to use the modified definitions.)

	</li><li>
	Use a suitable shared library mechanism for linking with the Library. A
	suitable mechanism is one that (1) uses at run time a copy of the
	library already present on the user's computer system, rather than
	copying library functions into the executable, and (2) will operate
	properly with a modified version of the library, if the user installs
	one, as long as the modified version is interface-compatible with the
	version that the work was made with.

	</li><li>
	Accompany the work with a written offer, valid for at
	least three years, to give the same user the materials
	specified in Subsection 6a, above, for a charge no more
	than the cost of performing this distribution.

	</li><li>
	If distribution of the work is made by offering access to copy
	from a designated place, offer equivalent access to copy the above
	specified materials from the same place.

	</li><li>
	Verify that the user has already received a copy of these
	materials or that you have already sent this user a copy.
	</li></ol>

	<p> For an executable, the required form of the “work that uses the
	Library” must include any data and utility programs needed for
	reproducing the executable from it. However, as a special exception,
	the materials to be distributed need not include anything that is
	normally distributed (in either source or binary form) with the major
	components (compiler, kernel, and so on) of the operating system on
	which the executable runs, unless that component itself accompanies the
	executable.
	</p>
	<p> It may happen that this requirement contradicts the license
	restrictions of other proprietary libraries that do not normally
	accompany the operating system. Such a contradiction means you cannot
	use both them and the Library together in an executable that you
	distribute.
	</p>
	</li><li>
	You may place library facilities that are a work based on the
	Library side-by-side in a single library together with other library
	facilities not covered by this License, and distribute such a combined
	library, provided that the separate distribution of the work based on
	the Library and of the other library facilities is otherwise
	permitted, and provided that you do these two things:

	<ol>
	<li>
	Accompany the combined library with a copy of the same work
	based on the Library, uncombined with any other library
	facilities. This must be distributed under the terms of the
	Sections above.

	</li><li>
	Give prominent notice with the combined library of the fact
	that part of it is a work based on the Library, and explaining
	where to find the accompanying uncombined form of the same work.
	</li></ol>

	</li><li>
	You may not copy, modify, sublicense, link with, or distribute
	the Library except as expressly provided under this License. Any
	attempt otherwise to copy, modify, sublicense, link with, or
	distribute the Library is void, and will automatically terminate your
	rights under this License. However, parties who have received copies,
	or rights, from you under this License will not have their licenses
	terminated so long as such parties remain in full compliance.

	</li><li>
	You are not required to accept this License, since you have not
	signed it. However, nothing else grants you permission to modify or
	distribute the Library or its derivative works. These actions are
	prohibited by law if you do not accept this License. Therefore, by
	modifying or distributing the Library (or any work based on the
	Library), you indicate your acceptance of this License to do so, and
	all its terms and conditions for copying, distributing or modifying
	the Library or works based on it.

	</li><li>
	Each time you redistribute the Library (or any work based on the
	Library), the recipient automatically receives a license from the
	original licensor to copy, distribute, link with or modify the Library
	subject to these terms and conditions. You may not impose any further
	restrictions on the recipients' exercise of the rights granted herein.
	You are not responsible for enforcing compliance by third parties with
	this License.

	</li><li>
	If, as a consequence of a court judgment or allegation of patent
	infringement or for any other reason (not limited to patent issues),
	conditions are imposed on you (whether by court order, agreement or
	otherwise) that contradict the conditions of this License, they do not
	excuse you from the conditions of this License. If you cannot
	distribute so as to satisfy simultaneously your obligations under this
	License and any other pertinent obligations, then as a consequence you
	may not distribute the Library at all. For example, if a patent
	license would not permit royalty-free redistribution of the Library by
	all those who receive copies directly or indirectly through you, then
	the only way you could satisfy both it and this License would be to
	refrain entirely from distribution of the Library.

	<p>If any portion of this section is held invalid or unenforceable under any
	particular circumstance, the balance of the section is intended to apply,
	and the section as a whole is intended to apply in other circumstances.
	</p>
	<p>It is not the purpose of this section to induce you to infringe any
	patents or other property right claims or to contest validity of any
	such claims; this section has the sole purpose of protecting the
	integrity of the free software distribution system which is
	implemented by public license practices. Many people have made
	generous contributions to the wide range of software distributed
	through that system in reliance on consistent application of that
	system; it is up to the author/donor to decide if he or she is willing
	to distribute software through any other system and a licensee cannot
	impose that choice.
	</p>
	<p>This section is intended to make thoroughly clear what is believed to
	be a consequence of the rest of this License.
	</p>
	</li><li>
	If the distribution and/or use of the Library is restricted in
	certain countries either by patents or by copyrighted interfaces, the
	original copyright holder who places the Library under this License may add
	an explicit geographical distribution limitation excluding those countries,
	so that distribution is permitted only in or among countries not thus
	excluded. In such case, this License incorporates the limitation as if
	written in the body of this License.

	</li><li>
	The Free Software Foundation may publish revised and/or new
	versions of the Lesser General Public License from time to time.
	Such new versions will be similar in spirit to the present version,
	but may differ in detail to address new problems or concerns.

	<p>Each version is given a distinguishing version number. If the Library
	specifies a version number of this License which applies to it and
	“any later version”, you have the option of following the terms and
	conditions either of that version or of any later version published by
	the Free Software Foundation. If the Library does not specify a
	license version number, you may choose any version ever published by
	the Free Software Foundation.
	</p>
	</li><li>
	If you wish to incorporate parts of the Library into other free
	programs whose distribution conditions are incompatible with these,
	write to the author to ask for permission. For software which is
	copyrighted by the Free Software Foundation, write to the Free
	Software Foundation; we sometimes make exceptions for this. Our
	decision will be guided by the two goals of preserving the free status
	of all derivatives of our free software and of promoting the sharing
	and reuse of software generally.

	<p align="center"> <b>NO WARRANTY</b>
	</p>
	</li><li>
	BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
	WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
	EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
	OTHER PARTIES PROVIDE THE LIBRARY “AS IS” WITHOUT WARRANTY OF ANY
	KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
	IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
	PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
	LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
	THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

	</li><li>
	IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
	WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
	AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
	FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
	CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
	LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
	RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
	FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
	SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
	DAMAGES.

	<h3 class="subheading"> How to Apply These Terms to Your New Libraries </h3>

	<p> If you develop a new library, and you want it to be of the greatest
	possible use to the public, we recommend making it free software that
	everyone can redistribute and change. You can do so by permitting
	redistribution under these terms (or, alternatively, under the terms of the
	ordinary General Public License).
	</p>
	<p> To apply these terms, attach the following notices to the library. It is
	safest to attach them to the start of each source file to most effectively
	convey the exclusion of warranty; and each file should have at least the
	“copyright” line and a pointer to where the full notice is found.

	PREAMBLE

	<p>The purpose of this License is to make a manual, textbook, or other
	functional and useful document <em>free</em> in the sense of freedom: to
	assure everyone the effective freedom to copy and redistribute it,
	with or without modifying it, either commercially or noncommercially.
	Secondarily, this License preserves for the author and publisher a way
	to get credit for their work, while not being considered responsible
	for modifications made by others.
	</p>
	<p>This License is a kind of “copyleft”, which means that derivative
	works of the document must themselves be free in the same sense. It
	complements the GNU General Public License, which is a copyleft
	license designed for free software.
	</p>
	<p>We have designed this License in order to use it for manuals for free
	software, because free software needs free documentation: a free
	program should come with manuals providing the same freedoms that the
	software does. But this License is not limited to software manuals;
	it can be used for any textual work, regardless of subject matter or
	whether it is published as a printed book. We recommend this License
	principally for works whose purpose is instruction or reference.
	</p>
	</li><li>
	APPLICABILITY AND DEFINITIONS

	<p>This License applies to any manual or other work, in any medium, that
	contains a notice placed by the copyright holder saying it can be
	distributed under the terms of this License. Such a notice grants a
	world-wide, royalty-free license, unlimited in duration, to use that
	work under the conditions stated herein. The “Document”, below,
	refers to any such manual or work. Any member of the public is a
	licensee, and is addressed as “you”. You accept the license if you
	copy, modify or distribute the work in a way requiring permission
	under copyright law.
	</p>
	<p>A “Modified Version” of the Document means any work containing the
	Document or a portion of it, either copied verbatim, or with
	modifications and/or translated into another language.
	</p>
	<p>A “Secondary Section” is a named appendix or a front-matter section
	of the Document that deals exclusively with the relationship of the
	publishers or authors of the Document to the Document's overall
	subject (or to related matters) and contains nothing that could fall
	directly within that overall subject. (Thus, if the Document is in
	part a textbook of mathematics, a Secondary Section may not explain
	any mathematics.) The relationship could be a matter of historical
	connection with the subject or with related matters, or of legal,
	commercial, philosophical, ethical or political position regarding
	them.
	</p>
	<p>The “Invariant Sections” are certain Secondary Sections whose titles
	are designated, as being those of Invariant Sections, in the notice
	that says that the Document is released under this License. If a
	section does not fit the above definition of Secondary then it is not
	allowed to be designated as Invariant. The Document may contain zero
	Invariant Sections. If the Document does not identify any Invariant
	Sections then there are none.
	</p>
	<p>The “Cover Texts” are certain short passages of text that are listed,
	as Front-Cover Texts or Back-Cover Texts, in the notice that says that
	the Document is released under this License. A Front-Cover Text may
	be at most 5 words, and a Back-Cover Text may be at most 25 words.
	</p>
	<p>A “Transparent” copy of the Document means a machine-readable copy,
	represented in a format whose specification is available to the
	general public, that is suitable for revising the document
	straightforwardly with generic text editors or (for images composed of
	pixels) generic paint programs or (for drawings) some widely available
	drawing editor, and that is suitable for input to text formatters or
	for automatic translation to a variety of formats suitable for input
	to text formatters. A copy made in an otherwise Transparent file
	format whose markup, or absence of markup, has been arranged to thwart
	or discourage subsequent modification by readers is not Transparent.
	An image format is not Transparent if used for any substantial amount
	of text. A copy that is not “Transparent” is called “Opaque”.
	</p>
	<p>Examples of suitable formats for Transparent copies include plain
	<small>ASCII</small> without markup, Texinfo input format, LaTeX input
	format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available
	<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>,
	PostScript or <acronym>PDF</acronym> designed for human modification. Examples
	of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and
	<acronym>JPG</acronym>. Opaque formats include proprietary formats that can be
	read and edited only by proprietary word processors, <acronym>SGML</acronym> or
	<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are
	not generally available, and the machine-generated <acronym>HTML</acronym>,
	PostScript or <acronym>PDF</acronym> produced by some word processors for
	output purposes only.
	</p>
	<p>The “Title Page” means, for a printed book, the title page itself,
	plus such following pages as are needed to hold, legibly, the material
	this License requires to appear in the title page. For works in
	formats which do not have any title page as such, “Title Page” means
	the text near the most prominent appearance of the work's title,
	preceding the beginning of the body of the text.
	</p>
	<p>A section “Entitled XYZ” means a named subunit of the Document whose
	title either is precisely XYZ or contains XYZ in parentheses following
	text that translates XYZ in another language. (Here XYZ stands for a
	specific section name mentioned below, such as “Acknowledgements”,
	“Dedications”, “Endorsements”, or “History”.) To “Preserve the Title”
	of such a section when you modify the Document means that it remains a
	section “Entitled XYZ” according to this definition.
	</p>
	<p>The Document may include Warranty Disclaimers next to the notice which
	states that this License applies to the Document. These Warranty
	Disclaimers are considered to be included by reference in this
	License, but only as regards disclaiming warranties: any other
	implication that these Warranty Disclaimers may have is void and has
	no effect on the meaning of this License.
	</p>
	</li><li>
	VERBATIM COPYING

	<p>You may copy and distribute the Document in any medium, either
	commercially or noncommercially, provided that this License, the
	copyright notices, and the license notice saying this License applies
	to the Document are reproduced in all copies, and that you add no other
	conditions whatsoever to those of this License. You may not use
	technical measures to obstruct or control the reading or further
	copying of the copies you make or distribute. However, you may accept
	compensation in exchange for copies. If you distribute a large enough
	number of copies you must also follow the conditions in section 3.
	</p>
	<p>You may also lend copies, under the same conditions stated above, and
	you may publicly display copies.
	</p>
	</li><li>
	COPYING IN QUANTITY

	<p>If you publish printed copies (or copies in media that commonly have
	printed covers) of the Document, numbering more than 100, and the
	Document's license notice requires Cover Texts, you must enclose the
	copies in covers that carry, clearly and legibly, all these Cover
	Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
	the back cover. Both covers must also clearly and legibly identify
	you as the publisher of these copies. The front cover must present
	the full title with all words of the title equally prominent and
	visible. You may add other material on the covers in addition.
	Copying with changes limited to the covers, as long as they preserve
	the title of the Document and satisfy these conditions, can be treated
	as verbatim copying in other respects.
	</p>
	<p>If the required texts for either cover are too voluminous to fit
	legibly, you should put the first ones listed (as many as fit
	reasonably) on the actual cover, and continue the rest onto adjacent
	pages.
	</p>
	<p>If you publish or distribute Opaque copies of the Document numbering
	more than 100, you must either include a machine-readable Transparent
	copy along with each Opaque copy, or state in or with each Opaque copy
	a computer-network location from which the general network-using
	public has access to download using public-standard network protocols
	a complete Transparent copy of the Document, free of added material.
	If you use the latter option, you must take reasonably prudent steps,
	when you begin distribution of Opaque copies in quantity, to ensure
	that this Transparent copy will remain thus accessible at the stated
	location until at least one year after the last time you distribute an
	Opaque copy (directly or through your agents or retailers) of that
	edition to the public.
	</p>
	<p>It is requested, but not required, that you contact the authors of the
	Document well before redistributing any large number of copies, to give
	them a chance to provide you with an updated version of the Document.
	</p>
	</li><li>
	MODIFICATIONS

	<p>You may copy and distribute a Modified Version of the Document under
	the conditions of sections 2 and 3 above, provided that you release
	the Modified Version under precisely this License, with the Modified
	Version filling the role of the Document, thus licensing distribution
	and modification of the Modified Version to whoever possesses a copy
	of it. In addition, you must do these things in the Modified Version:
	</p>
	<ol>
	<li>
	Use in the Title Page (and on the covers, if any) a title distinct
	from that of the Document, and from those of previous versions
	(which should, if there were any, be listed in the History section
	of the Document). You may use the same title as a previous version
	if the original publisher of that version gives permission.

	</li><li>
	List on the Title Page, as authors, one or more persons or entities
	responsible for authorship of the modifications in the Modified
	Version, together with at least five of the principal authors of the
	Document (all of its principal authors, if it has fewer than five),
	unless they release you from this requirement.

	</li><li>
	State on the Title page the name of the publisher of the
	Modified Version, as the publisher.

	</li><li>
	Preserve all the copyright notices of the Document.

	</li><li>
	Add an appropriate copyright notice for your modifications
	adjacent to the other copyright notices.

	</li><li>
	Include, immediately after the copyright notices, a license notice
	giving the public permission to use the Modified Version under the
	terms of this License, in the form shown in the Addendum below.

	</li><li>
	Preserve in that license notice the full lists of Invariant Sections
	and required Cover Texts given in the Document's license notice.

	</li><li>
	Include an unaltered copy of this License.

	</li><li>
	Preserve the section Entitled “History”, Preserve its Title, and add
	to it an item stating at least the title, year, new authors, and
	publisher of the Modified Version as given on the Title Page. If
	there is no section Entitled “History” in the Document, create one
	stating the title, year, authors, and publisher of the Document as
	given on its Title Page, then add an item describing the Modified
	Version as stated in the previous sentence.

	</li><li>
	Preserve the network location, if any, given in the Document for
	public access to a Transparent copy of the Document, and likewise
	the network locations given in the Document for previous versions
	it was based on. These may be placed in the “History” section.
	You may omit a network location for a work that was published at
	least four years before the Document itself, or if the original
	publisher of the version it refers to gives permission.

	</li><li>
	For any section Entitled “Acknowledgements” or “Dedications”, Preserve
	the Title of the section, and preserve in the section all the
	substance and tone of each of the contributor acknowledgements and/or
	dedications given therein.

	</li><li>
	Preserve all the Invariant Sections of the Document,
	unaltered in their text and in their titles. Section numbers
	or the equivalent are not considered part of the section titles.

	</li><li>
	Delete any section Entitled “Endorsements”. Such a section
	may not be included in the Modified Version.

	</li><li>
	Do not retitle any existing section to be Entitled “Endorsements” or
	to conflict in title with any Invariant Section.

	</li><li>
	Preserve any Warranty Disclaimers.
	</li></ol>

	<p>If the Modified Version includes new front-matter sections or
	appendices that qualify as Secondary Sections and contain no material
	copied from the Document, you may at your option designate some or all
	of these sections as invariant. To do this, add their titles to the
	list of Invariant Sections in the Modified Version's license notice.
	These titles must be distinct from any other section titles.
	</p>
	<p>You may add a section Entitled “Endorsements”, provided it contains
	nothing but endorsements of your Modified Version by various
	parties—for example, statements of peer review or that the text has
	been approved by an organization as the authoritative definition of a
	standard.
	</p>
	<p>You may add a passage of up to five words as a Front-Cover Text, and a
	passage of up to 25 words as a Back-Cover Text, to the end of the list
	of Cover Texts in the Modified Version. Only one passage of
	Front-Cover Text and one of Back-Cover Text may be added by (or
	through arrangements made by) any one entity. If the Document already
	includes a cover text for the same cover, previously added by you or
	by arrangement made by the same entity you are acting on behalf of,
	you may not add another; but you may replace the old one, on explicit
	permission from the previous publisher that added the old one.
	</p>
	<p>The author(s) and publisher(s) of the Document do not by this License
	give permission to use their names for publicity for or to assert or
	imply endorsement of any Modified Version.
	</p>
	</li><li>
	COMBINING DOCUMENTS

	<p>You may combine the Document with other documents released under this
	License, under the terms defined in section 4 above for modified
	versions, provided that you include in the combination all of the
	Invariant Sections of all of the original documents, unmodified, and
	list them all as Invariant Sections of your combined work in its
	license notice, and that you preserve all their Warranty Disclaimers.
	</p>
	<p>The combined work need only contain one copy of this License, and
	multiple identical Invariant Sections may be replaced with a single
	copy. If there are multiple Invariant Sections with the same name but
	different contents, make the title of each such section unique by
	adding at the end of it, in parentheses, the name of the original
	author or publisher of that section if known, or else a unique number.
	Make the same adjustment to the section titles in the list of
	Invariant Sections in the license notice of the combined work.
	</p>
	<p>In the combination, you must combine any sections Entitled “History”
	in the various original documents, forming one section Entitled
	“History”; likewise combine any sections Entitled “Acknowledgements”,
	and any sections Entitled “Dedications”. You must delete all
	sections Entitled “Endorsements.”
	</p>
	</li><li>
	COLLECTIONS OF DOCUMENTS

	<p>You may make a collection consisting of the Document and other documents
	released under this License, and replace the individual copies of this
	License in the various documents with a single copy that is included in
	the collection, provided that you follow the rules of this License for
	verbatim copying of each of the documents in all other respects.
	</p>
	<p>You may extract a single document from such a collection, and distribute
	it individually under this License, provided you insert a copy of this
	License into the extracted document, and follow this License in all
	other respects regarding verbatim copying of that document.
	</p>
	</li><li>
	AGGREGATION WITH INDEPENDENT WORKS

	<p>A compilation of the Document or its derivatives with other separate
	and independent documents or works, in or on a volume of a storage or
	distribution medium, is called an “aggregate” if the copyright
	resulting from the compilation is not used to limit the legal rights
	of the compilation's users beyond what the individual works permit.
	When the Document is included in an aggregate, this License does not
	apply to the other works in the aggregate which are not themselves
	derivative works of the Document.
	</p>
	<p>If the Cover Text requirement of section 3 is applicable to these
	copies of the Document, then if the Document is less than one half of
	the entire aggregate, the Document's Cover Texts may be placed on
	covers that bracket the Document within the aggregate, or the
	electronic equivalent of covers if the Document is in electronic form.
	Otherwise they must appear on printed covers that bracket the whole
	aggregate.
	</p>
	</li><li>
	TRANSLATION

	<p>Translation is considered a kind of modification, so you may
	distribute translations of the Document under the terms of section 4.
	Replacing Invariant Sections with translations requires special
	permission from their copyright holders, but you may include
	translations of some or all Invariant Sections in addition to the
	original versions of these Invariant Sections. You may include a
	translation of this License, and all the license notices in the
	Document, and any Warranty Disclaimers, provided that you also include
	the original English version of this License and the original versions
	of those notices and disclaimers. In case of a disagreement between
	the translation and the original version of this License or a notice
	or disclaimer, the original version will prevail.
	</p>
	<p>If a section in the Document is Entitled “Acknowledgements”,
	“Dedications”, or “History”, the requirement (section 4) to Preserve
	its Title (section 1) will typically require changing the actual
	title.
	</p>
	</li><li>
	TERMINATION

	<p>You may not copy, modify, sublicense, or distribute the Document except
	as expressly provided for under this License. Any other attempt to
	copy, modify, sublicense or distribute the Document is void, and will
	automatically terminate your rights under this License. However,
	parties who have received copies, or rights, from you under this
	License will not have their licenses terminated so long as such
	parties remain in full compliance.
	</p>
	</li><li>
	FUTURE REVISIONS OF THIS LICENSE

	<p>The Free Software Foundation may publish new, revised versions
	of the GNU Free Documentation License from time to time. Such new
	versions will be similar in spirit to the present version, but may
	differ in detail to address new problems or concerns. See
	<a href="https://www.gnu.org/copyleft/">https://www.gnu.org/copyleft/</a>.
	</p>
	<p>Each version of the License is given a distinguishing version number.
	If the Document specifies that a particular numbered version of this
	License “or any later version” applies to it, you have the option of
	following the terms and conditions either of that specified version or
	of any later version that has been published (not as a draft) by the
	Free Software Foundation. If the Document does not specify a version
	number of this License, you may choose any version ever published (not
	as a draft) by the Free Software Foundation.
	</p></li></ol>

	<h2 class="heading"> ADDENDUM: How to use this License for your documents </h2>

	<p>To use this License in a document you have written, include a copy of
	the License in the document and put the following copyright and
	license notices just after the title page:
	</p>
	<table><tr><td> </td><td><pre class="smallexample"> Copyright (C) <var>year</var> <var>your name</var>.
	Permission is granted to copy, distribute and/or modify this document
	under the terms of the GNU Free Documentation License, Version 1.2
	or any later version published by the Free Software Foundation;
	with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
	Texts. A copy of the license is included in the section entitled ``GNU
	Free Documentation License''.
	</pre></td></tr></table>

	<p>If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
	replace the “with…Texts.” line with this:
	</p>
	<table><tr><td> </td><td><pre class="smallexample"> with the Invariant Sections being <var>list their titles</var>, with
	the Front-Cover Texts being <var>list</var>, and with the Back-Cover Texts
	being <var>list</var>.
	</pre></td></tr></table>

	<p>If you have Invariant Sections without Cover Texts, or some other
	combination of the three, merge those two alternatives to suit the
	situation.
	</p>
	<p>If your document contains nontrivial examples of program code, we
	recommend releasing these examples in parallel under your choice of
	free software license, such as the GNU General Public License,
	to permit their use in free software.
	</p>
