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

	<p>The GNU General Public License is a free, copyleft license for
	software and other kinds of works.
	</p>
	<p>The licenses for most software and other practical works are designed
	to take away your freedom to share and change the works. By contrast,
	the GNU General Public License is intended to guarantee your freedom
	to share and change all versions of a program—to make sure it remains
	free software for all its users. We, the Free Software Foundation,
	use the GNU General Public License for most of our software; it
	applies also to any other work released this way by its authors. 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
	them 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 prevent others from denying you
	these rights or asking you to surrender the rights. Therefore, you
	have certain responsibilities if you distribute copies of the
	software, or if you modify it: responsibilities to respect the freedom
	of others.
	</p>
	<p>For example, if you distribute copies of such a program, whether
	gratis or for a fee, you must pass on to the recipients the same
	freedoms that you received. 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>Developers that use the GNU GPL protect your rights with two steps:
	(1) assert copyright on the software, and (2) offer you this License
	giving you legal permission to copy, distribute and/or modify it.
	</p>
	<p>For the developers' and authors' protection, the GPL clearly explains
	that there is no warranty for this free software. For both users' and
	authors' sake, the GPL requires that modified versions be marked as
	changed, so that their problems will not be attributed erroneously to
	authors of previous versions.
	</p>
	<p>Some devices are designed to deny users access to install or run
	modified versions of the software inside them, although the
	manufacturer can do so. This is fundamentally incompatible with the
	aim of protecting users' freedom to change the software. The
	systematic pattern of such abuse occurs in the area of products for
	individuals to use, which is precisely where it is most unacceptable.
	Therefore, we have designed this version of the GPL to prohibit the
	practice for those products. If such problems arise substantially in
	other domains, we stand ready to extend this provision to those
	domains in future versions of the GPL, as needed to protect the
	freedom of users.
	</p>
	<p>Finally, every program is threatened constantly by software patents.
	States should not allow patents to restrict development and use of
	software on general-purpose computers, but in those that do, we wish
	to avoid the special danger that patents applied to a free program
	could make it effectively proprietary. To prevent this, the GPL
	assures that patents cannot be used to render the program non-free.
	</p>
	<p>The precise terms and conditions for copying, distribution and
	modification follow.
	</p>
	<a name="SEC40"></a>
	<h2 class="heading"> TERMS AND CONDITIONS </h2>

	<ol>
	<li> Definitions.

	<p>“This License” refers to version 3 of the GNU General Public License.
	</p>
	<p>“Copyright” also means copyright-like laws that apply to other kinds
	of works, such as semiconductor masks.
	</p>
	<p>“The Program” refers to any copyrightable work licensed under this
	License. Each licensee is addressed as “you”. “Licensees” and
	“recipients” may be individuals or organizations.
	</p>
	<p>To “modify” a work means to copy from or adapt all or part of the work
	in a fashion requiring copyright permission, other than the making of
	an exact copy. The resulting work is called a “modified version” of
	the earlier work or a work “based on” the earlier work.
	</p>
	<p>A “covered work” means either the unmodified Program or a work based
	on the Program.
	</p>
	<p>To “propagate” a work means to do anything with it that, without
	permission, would make you directly or secondarily liable for
	infringement under applicable copyright law, except executing it on a
	computer or modifying a private copy. Propagation includes copying,
	distribution (with or without modification), making available to the
	public, and in some countries other activities as well.
	</p>
	<p>To “convey” a work means any kind of propagation that enables other
	parties to make or receive copies. Mere interaction with a user
	through a computer network, with no transfer of a copy, is not
	conveying.
	</p>
	<p>An interactive user interface displays “Appropriate Legal Notices” to
	the extent that it includes a convenient and prominently visible
	feature that (1) displays an appropriate copyright notice, and (2)
	tells the user that there is no warranty for the work (except to the
	extent that warranties are provided), that licensees may convey the
	work under this License, and how to view a copy of this License. If
	the interface presents a list of user commands or options, such as a
	menu, a prominent item in the list meets this criterion.
	</p>
	</li><li> Source Code.

	<p>The “source code” for a work means the preferred form of the work for
	making modifications to it. “Object code” means any non-source form
	of a work.
	</p>
	<p>A “Standard Interface” means an interface that either is an official
	standard defined by a recognized standards body, or, in the case of
	interfaces specified for a particular programming language, one that
	is widely used among developers working in that language.
	</p>
	<p>The “System Libraries” of an executable work include anything, other
	than the work as a whole, that (a) is included in the normal form of
	packaging a Major Component, but which is not part of that Major
	Component, and (b) serves only to enable use of the work with that
	Major Component, or to implement a Standard Interface for which an
	implementation is available to the public in source code form. A
	“Major Component”, in this context, means a major essential component
	(kernel, window system, and so on) of the specific operating system
	(if any) on which the executable work runs, or a compiler used to
	produce the work, or an object code interpreter used to run it.
	</p>
	<p>The “Corresponding Source” for a work in object code form means all
	the source code needed to generate, install, and (for an executable
	work) run the object code and to modify the work, including scripts to
	control those activities. However, it does not include the work's
	System Libraries, or general-purpose tools or generally available free
	programs which are used unmodified in performing those activities but
	which are not part of the work. For example, Corresponding Source
	includes interface definition files associated with source files for
	the work, and the source code for shared libraries and dynamically
	linked subprograms that the work is specifically designed to require,
	such as by intimate data communication or control flow between those
	subprograms and other parts of the work.
	</p>
	<p>The Corresponding Source need not include anything that users can
	regenerate automatically from other parts of the Corresponding Source.
	</p>
	<p>The Corresponding Source for a work in source code form is that same
	work.
	</p>
	</li><li> Basic Permissions.

	<p>All rights granted under this License are granted for the term of
	copyright on the Program, and are irrevocable provided the stated
	conditions are met. This License explicitly affirms your unlimited
	permission to run the unmodified Program. The output from running a
	covered work is covered by this License only if the output, given its
	content, constitutes a covered work. This License acknowledges your
	rights of fair use or other equivalent, as provided by copyright law.
	</p>
	<p>You may make, run and propagate covered works that you do not convey,
	without conditions so long as your license otherwise remains in force.
	You may convey covered works to others for the sole purpose of having
	them make modifications exclusively for you, or provide you with
	facilities for running those works, provided that you comply with the
	terms of this License in conveying all material for which you do not
	control copyright. Those thus making or running the covered works for
	you must do so exclusively on your behalf, under your direction and
	control, on terms that prohibit them from making any copies of your
	copyrighted material outside their relationship with you.
	</p>
	<p>Conveying under any other circumstances is permitted solely under the
	conditions stated below. Sublicensing is not allowed; section 10
	makes it unnecessary.
	</p>
	</li><li> Protecting Users' Legal Rights From Anti-Circumvention Law.

	<p>No covered work shall be deemed part of an effective technological
	measure under any applicable law fulfilling obligations under article
	11 of the WIPO copyright treaty adopted on 20 December 1996, or
	similar laws prohibiting or restricting circumvention of such
	measures.
	</p>
	<p>When you convey a covered work, you waive any legal power to forbid
	circumvention of technological measures to the extent such
	circumvention is effected by exercising rights under this License with
	respect to the covered work, and you disclaim any intention to limit
	operation or modification of the work as a means of enforcing, against
	the work's users, your or third parties' legal rights to forbid
	circumvention of technological measures.
	</p>
	</li><li> Conveying Verbatim Copies.

	<p>You may convey 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;
	keep intact all notices stating that this License and any
	non-permissive terms added in accord with section 7 apply to the code;
	keep intact all notices of the absence of any warranty; and give all
	recipients a copy of this License along with the Program.
	</p>
	<p>You may charge any price or no price for each copy that you convey,
	and you may offer support or warranty protection for a fee.
	</p>
	</li><li> Conveying Modified Source Versions.

	<p>You may convey a work based on the Program, or the modifications to
	produce it from the Program, in the form of source code under the
	terms of section 4, provided that you also meet all of these
	conditions:
	</p>
	<ol>
	<li>
	The work must carry prominent notices stating that you modified it,
	and giving a relevant date.

	</li><li>
	The work must carry prominent notices stating that it is released
	under this License and any conditions added under section 7. This
	requirement modifies the requirement in section 4 to “keep intact all
	notices”.

	</li><li>
	You must license the entire work, as a whole, under this License to
	anyone who comes into possession of a copy. This License will
	therefore apply, along with any applicable section 7 additional terms,
	to the whole of the work, and all its parts, regardless of how they
	are packaged. This License gives no permission to license the work in
	any other way, but it does not invalidate such permission if you have
	separately received it.

	</li><li>
	If the work has interactive user interfaces, each must display
	Appropriate Legal Notices; however, if the Program has interactive
	interfaces that do not display Appropriate Legal Notices, your work
	need not make them do so.
	</li></ol>

	<p>A compilation of a covered work with other separate and independent
	works, which are not by their nature extensions of the covered work,
	and which are not combined with it such as to form a larger program,
	in or on a volume of a storage or distribution medium, is called an
	“aggregate” if the compilation and its resulting copyright are not
	used to limit the access or legal rights of the compilation's users
	beyond what the individual works permit. Inclusion of a covered work
	in an aggregate does not cause this License to apply to the other
	parts of the aggregate.
	</p>
	</li><li> Conveying Non-Source Forms.

	<p>You may convey a covered work in object code form under the terms of
	sections 4 and 5, provided that you also convey the machine-readable
	Corresponding Source under the terms of this License, in one of these
	ways:
	</p>
	<ol>
	<li>
	Convey the object code in, or embodied in, a physical product
	(including a physical distribution medium), accompanied by the
	Corresponding Source fixed on a durable physical medium customarily
	used for software interchange.

	</li><li>
	Convey the object code in, or embodied in, a physical product
	(including a physical distribution medium), accompanied by a written
	offer, valid for at least three years and valid for as long as you
	offer spare parts or customer support for that product model, to give
	anyone who possesses the object code either (1) a copy of the
	Corresponding Source for all the software in the product that is
	covered by this License, on a durable physical medium customarily used
	for software interchange, for a price no more than your reasonable
	cost of physically performing this conveying of source, or (2) access
	to copy the Corresponding Source from a network server at no charge.

	</li><li>
	Convey individual copies of the object code with a copy of the written
	offer to provide the Corresponding Source. This alternative is
	allowed only occasionally and noncommercially, and only if you
	received the object code with such an offer, in accord with subsection
	6b.

	</li><li>
	Convey the object code by offering access from a designated place
	(gratis or for a charge), and offer equivalent access to the
	Corresponding Source in the same way through the same place at no
	further charge. You need not require recipients to copy the
	Corresponding Source along with the object code. If the place to copy
	the object code is a network server, the Corresponding Source may be
	on a different server (operated by you or a third party) that supports
	equivalent copying facilities, provided you maintain clear directions
	next to the object code saying where to find the Corresponding Source.
	Regardless of what server hosts the Corresponding Source, you remain
	obligated to ensure that it is available for as long as needed to
	satisfy these requirements.

	</li><li>
	Convey the object code using peer-to-peer transmission, provided you
	inform other peers where the object code and Corresponding Source of
	the work are being offered to the general public at no charge under
	subsection 6d.

	</li></ol>

	<p>A separable portion of the object code, whose source code is excluded
	from the Corresponding Source as a System Library, need not be
	included in conveying the object code work.
	</p>
	<p>A “User Product” is either (1) a “consumer product”, which means any
	tangible personal property which is normally used for personal,
	family, or household purposes, or (2) anything designed or sold for
	incorporation into a dwelling. In determining whether a product is a
	consumer product, doubtful cases shall be resolved in favor of
	coverage. For a particular product received by a particular user,
	“normally used” refers to a typical or common use of that class of
	product, regardless of the status of the particular user or of the way
	in which the particular user actually uses, or expects or is expected
	to use, the product. A product is a consumer product regardless of
	whether the product has substantial commercial, industrial or
	non-consumer uses, unless such uses represent the only significant
	mode of use of the product.
	</p>
	<p>“Installation Information” for a User Product means any methods,
	procedures, authorization keys, or other information required to
	install and execute modified versions of a covered work in that User
	Product from a modified version of its Corresponding Source. The
	information must suffice to ensure that the continued functioning of
	the modified object code is in no case prevented or interfered with
	solely because modification has been made.
	</p>
	<p>If you convey an object code work under this section in, or with, or
	specifically for use in, a User Product, and the conveying occurs as
	part of a transaction in which the right of possession and use of the
	User Product is transferred to the recipient in perpetuity or for a
	fixed term (regardless of how the transaction is characterized), the
	Corresponding Source conveyed under this section must be accompanied
	by the Installation Information. But this requirement does not apply
	if neither you nor any third party retains the ability to install
	modified object code on the User Product (for example, the work has
	been installed in ROM).
	</p>
	<p>The requirement to provide Installation Information does not include a
	requirement to continue to provide support service, warranty, or
	updates for a work that has been modified or installed by the
	recipient, or for the User Product in which it has been modified or
	installed. Access to a network may be denied when the modification
	itself materially and adversely affects the operation of the network
	or violates the rules and protocols for communication across the
	network.
	</p>
	<p>Corresponding Source conveyed, and Installation Information provided,
	in accord with this section must be in a format that is publicly
	documented (and with an implementation available to the public in
	source code form), and must require no special password or key for
	unpacking, reading or copying.
	</p>
	</li><li> Additional Terms.

	<p>“Additional permissions” are terms that supplement the terms of this
	License by making exceptions from one or more of its conditions.
	Additional permissions that are applicable to the entire Program shall
	be treated as though they were included in this License, to the extent
	that they are valid under applicable law. If additional permissions
	apply only to part of the Program, that part may be used separately
	under those permissions, but the entire Program remains governed by
	this License without regard to the additional permissions.
	</p>
	<p>When you convey a copy of a covered work, you may at your option
	remove any additional permissions from that copy, or from any part of
	it. (Additional permissions may be written to require their own
	removal in certain cases when you modify the work.) You may place
	additional permissions on material, added by you to a covered work,
	for which you have or can give appropriate copyright permission.
	</p>
	<p>Notwithstanding any other provision of this License, for material you
	add to a covered work, you may (if authorized by the copyright holders
	of that material) supplement the terms of this License with terms:
	</p>
	<ol>
	<li>
	Disclaiming warranty or limiting liability differently from the terms
	of sections 15 and 16 of this License; or

	</li><li>
	Requiring preservation of specified reasonable legal notices or author
	attributions in that material or in the Appropriate Legal Notices
	displayed by works containing it; or

	</li><li>
	Prohibiting misrepresentation of the origin of that material, or
	requiring that modified versions of such material be marked in
	reasonable ways as different from the original version; or

	</li><li>
	Limiting the use for publicity purposes of names of licensors or
	authors of the material; or

	</li><li>
	Declining to grant rights under trademark law for use of some trade
	names, trademarks, or service marks; or

	</li><li>
	Requiring indemnification of licensors and authors of that material by
	anyone who conveys the material (or modified versions of it) with
	contractual assumptions of liability to the recipient, for any
	liability that these contractual assumptions directly impose on those
	licensors and authors.
	</li></ol>

	<p>All other non-permissive additional terms are considered “further
	restrictions” within the meaning of section 10. If the Program as you
	received it, or any part of it, contains a notice stating that it is
	governed by this License along with a term that is a further
	restriction, you may remove that term. If a license document contains
	a further restriction but permits relicensing or conveying under this
	License, you may add to a covered work material governed by the terms
	of that license document, provided that the further restriction does
	not survive such relicensing or conveying.
	</p>
	<p>If you add terms to a covered work in accord with this section, you
	must place, in the relevant source files, a statement of the
	additional terms that apply to those files, or a notice indicating
	where to find the applicable terms.
	</p>
	<p>Additional terms, permissive or non-permissive, may be stated in the
	form of a separately written license, or stated as exceptions; the
	above requirements apply either way.
	</p>
	</li><li> Termination.

	<p>You may not propagate or modify a covered work except as expressly
	provided under this License. Any attempt otherwise to propagate or
	modify it is void, and will automatically terminate your rights under
	this License (including any patent licenses granted under the third
	paragraph of section 11).
	</p>
	<p>However, if you cease all violation of this License, then your license
	from a particular copyright holder is reinstated (a) provisionally,
	unless and until the copyright holder explicitly and finally
	terminates your license, and (b) permanently, if the copyright holder
	fails to notify you of the violation by some reasonable means prior to
	60 days after the cessation.
	</p>
	<p>Moreover, your license from a particular copyright holder is
	reinstated permanently if the copyright holder notifies you of the
	violation by some reasonable means, this is the first time you have
	received notice of violation of this License (for any work) from that
	copyright holder, and you cure the violation prior to 30 days after
	your receipt of the notice.
	</p>
	<p>Termination of your rights under this section does not terminate the
	licenses of parties who have received copies or rights from you under
	this License. If your rights have been terminated and not permanently
	reinstated, you do not qualify to receive new licenses for the same
	material under section 10.
	</p>
	</li><li> Acceptance Not Required for Having Copies.

	<p>You are not required to accept this License in order to receive or run
	a copy of the Program. Ancillary propagation of a covered work
	occurring solely as a consequence of using peer-to-peer transmission
	to receive a copy likewise does not require acceptance. However,
	nothing other than this License grants you permission to propagate or
	modify any covered work. These actions infringe copyright if you do
	not accept this License. Therefore, by modifying or propagating a
	covered work, you indicate your acceptance of this License to do so.
	</p>
	</li><li> Automatic Licensing of Downstream Recipients.

	<p>Each time you convey a covered work, the recipient automatically
	receives a license from the original licensors, to run, modify and
	propagate that work, subject to this License. You are not responsible
	for enforcing compliance by third parties with this License.
	</p>
	<p>An “entity transaction” is a transaction transferring control of an
	organization, or substantially all assets of one, or subdividing an
	organization, or merging organizations. If propagation of a covered
	work results from an entity transaction, each party to that
	transaction who receives a copy of the work also receives whatever
	licenses to the work the party's predecessor in interest had or could
	give under the previous paragraph, plus a right to possession of the
	Corresponding Source of the work from the predecessor in interest, if
	the predecessor has it or can get it with reasonable efforts.
	</p>
	<p>You may not impose any further restrictions on the exercise of the
	rights granted or affirmed under this License. For example, you may
	not impose a license fee, royalty, or other charge for exercise of
	rights granted under this License, and you may not initiate litigation
	(including a cross-claim or counterclaim in a lawsuit) alleging that
	any patent claim is infringed by making, using, selling, offering for
	sale, or importing the Program or any portion of it.
	</p>
	</li><li> Patents.

	<p>A “contributor” is a copyright holder who authorizes use under this
	License of the Program or a work on which the Program is based. The
	work thus licensed is called the contributor's “contributor version”.
	</p>
	<p>A contributor's “essential patent claims” are all patent claims owned
	or controlled by the contributor, whether already acquired or
	hereafter acquired, that would be infringed by some manner, permitted
	by this License, of making, using, or selling its contributor version,
	but do not include claims that would be infringed only as a
	consequence of further modification of the contributor version. For
	purposes of this definition, “control” includes the right to grant
	patent sublicenses in a manner consistent with the requirements of
	this License.
	</p>
	<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
	patent license under the contributor's essential patent claims, to
	make, use, sell, offer for sale, import and otherwise run, modify and
	propagate the contents of its contributor version.
	</p>
	<p>In the following three paragraphs, a “patent license” is any express
	agreement or commitment, however denominated, not to enforce a patent
	(such as an express permission to practice a patent or covenant not to
	sue for patent infringement). To “grant” such a patent license to a
	party means to make such an agreement or commitment not to enforce a
	patent against the party.
	</p>
	<p>If you convey a covered work, knowingly relying on a patent license,
	and the Corresponding Source of the work is not available for anyone
	to copy, free of charge and under the terms of this License, through a
	publicly available network server or other readily accessible means,
	then you must either (1) cause the Corresponding Source to be so
	available, or (2) arrange to deprive yourself of the benefit of the
	patent license for this particular work, or (3) arrange, in a manner
	consistent with the requirements of this License, to extend the patent
	license to downstream recipients. “Knowingly relying” means you have
	actual knowledge that, but for the patent license, your conveying the
	covered work in a country, or your recipient's use of the covered work
	in a country, would infringe one or more identifiable patents in that
	country that you have reason to believe are valid.
	</p>
	<p>If, pursuant to or in connection with a single transaction or
	arrangement, you convey, or propagate by procuring conveyance of, a
	covered work, and grant a patent license to some of the parties
	receiving the covered work authorizing them to use, propagate, modify
	or convey a specific copy of the covered work, then the patent license
	you grant is automatically extended to all recipients of the covered
	work and works based on it.
	</p>
	<p>A patent license is “discriminatory” if it does not include within the
	scope of its coverage, prohibits the exercise of, or is conditioned on
	the non-exercise of one or more of the rights that are specifically
	granted under this License. You may not convey a covered work if you
	are a party to an arrangement with a third party that is in the
	business of distributing software, under which you make payment to the
	third party based on the extent of your activity of conveying the
	work, and under which the third party grants, to any of the parties
	who would receive the covered work from you, a discriminatory patent
	license (a) in connection with copies of the covered work conveyed by
	you (or copies made from those copies), or (b) primarily for and in
	connection with specific products or compilations that contain the
	covered work, unless you entered into that arrangement, or that patent
	license was granted, prior to 28 March 2007.
	</p>
	<p>Nothing in this License shall be construed as excluding or limiting
	any implied license or other defenses to infringement that may
	otherwise be available to you under applicable patent law.
	</p>
	</li><li> No Surrender of Others' Freedom.

	<p>If 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 convey
	a covered work so as to satisfy simultaneously your obligations under
	this License and any other pertinent obligations, then as a
	consequence you may not convey it at all. For example, if you agree
	to terms that obligate you to collect a royalty for further conveying
	from those to whom you convey the Program, the only way you could
	satisfy both those terms and this License would be to refrain entirely
	from conveying the Program.
	</p>
	</li><li> Use with the GNU Affero General Public License.

	<p>Notwithstanding any other provision of this License, you have
	permission to link or combine any covered work with a work licensed
	under version 3 of the GNU Affero General Public License into a single
	combined work, and to convey the resulting work. The terms of this
	License will continue to apply to the part which is the covered work,
	but the special requirements of the GNU Affero General Public License,
	section 13, concerning interaction through a network will apply to the
	combination as such.
	</p>
	</li><li> Revised Versions of this License.

	<p>The Free Software Foundation may publish revised and/or new versions
	of the GNU 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>
	<p>Each version is given a distinguishing version number. If the Program
	specifies that a certain numbered version of the GNU General Public
	License “or any later version” applies to it, you have the option of
	following the terms and conditions either of that numbered version or
	of any later version published by the Free Software Foundation. If
	the Program does not specify a version number of the GNU General
	Public License, you may choose any version ever published by the Free
	Software Foundation.
	</p>
	<p>If the Program specifies that a proxy can decide which future versions
	of the GNU General Public License can be used, that proxy's public
	statement of acceptance of a version permanently authorizes you to
	choose that version for the Program.
	</p>
	<p>Later license versions may give you additional or different
	permissions. However, no additional obligations are imposed on any
	author or copyright holder as a result of your choosing to follow a
	later version.
	</p>
	</li><li> Disclaimer of Warranty.

	<p>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.
	</p>
	</li><li> Limitation of Liability.

	<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
	CONVEYS 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.
	</p>
	</li><li> Interpretation of Sections 15 and 16.

	<p>If the disclaimer of warranty and limitation of liability provided
	above cannot be given local legal effect according to their terms,
	reviewing courts shall apply local law that most closely approximates
	an absolute waiver of all civil liability in connection with the
	Program, unless a warranty or assumption of liability accompanies a
	copy of the Program in return for a fee.

	<h2 class="heading"> 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
	state 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>

	<p>The hypothetical commands ‘<samp>show w</samp>’ and ‘<samp>show c</samp>’ should show

	<p>You should also get your employer (if you work as a programmer) or school,

	<li>
	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
	ASCII without markup, Texinfo input format, LaTeX input
	format, SGML or XML using a publicly available
	DTD, and standard-conforming simple HTML,
	PostScript or PDF designed for human modification. Examples
	of transparent image formats include PNG, XCF and
	JPG. Opaque formats include proprietary formats that can be
	read and edited only by proprietary word processors, SGML or
	XML for which the DTD and/or processing tools are
	not generally available, and the machine-generated HTML,
	PostScript or PDF 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>The “publisher” means any person or entity that distributes copies
	of the Document to the public.
	</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 under this License. Any attempt
	otherwise to copy, modify, sublicense, or distribute it is void, and
	will automatically terminate your rights under this License.
	</p>
	<p>However, if you cease all violation of this License, then your license
	from a particular copyright holder is reinstated (a) provisionally,
	unless and until the copyright holder explicitly and finally
	terminates your license, and (b) permanently, if the copyright holder
	fails to notify you of the violation by some reasonable means prior to
	60 days after the cessation.
	</p>
	<p>Moreover, your license from a particular copyright holder is
	reinstated permanently if the copyright holder notifies you of the
	violation by some reasonable means, this is the first time you have
	received notice of violation of this License (for any work) from that
	copyright holder, and you cure the violation prior to 30 days after
	your receipt of the notice.
	</p>
	<p>Termination of your rights under this section does not terminate the
	licenses of parties who have received copies or rights from you under
	this License. If your rights have been terminated and not permanently
	reinstated, receipt of a copy of some or all of the same material does
	not give you any rights to use it.
	</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. If the Document
	specifies that a proxy can decide which future versions of this
	License can be used, that proxy's public statement of acceptance of a
	version permanently authorizes you to choose that version for the
	Document.
	</p>
	</li><li>
	RELICENSING

	<p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any
	World Wide Web server that publishes copyrightable works and also
	provides prominent facilities for anybody to edit those works. A
	public wiki that anybody can edit is an example of such a server. A
	“Massive Multiauthor Collaboration” (or “MMC”) contained in the
	site means any set of copyrightable works thus published on the MMC
	site.
	</p>
	<p>“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0
	license published by Creative Commons Corporation, a not-for-profit
	corporation with a principal place of business in San Francisco,
	California, as well as future copyleft versions of that license
	published by that same organization.
	</p>
	<p>“Incorporate” means to publish or republish a Document, in whole or
	in part, as part of another Document.
	</p>
	<p>An MMC is “eligible for relicensing” if it is licensed under this
	License, and if all works that were first published under this License
	somewhere other than this MMC, and subsequently incorporated in whole
	or in part into the MMC, (1) had no cover texts or invariant sections,
	and (2) were thus incorporated prior to November 1, 2008.
	</p>
	<p>The operator of an MMC Site may republish an MMC contained in the site
	under CC-BY-SA on the same site at any time before August 1, 2009,
	provided the MMC is eligible for relicensing.

	<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 1.3
	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>
