       gpl - GNU General Public	License

   GNU General Public License
   Version 3, 29 June 2007
	       Copyright (c) 2007 Free Software	Foundation, Inc. <>

	       Everyone	is permitted to	copy and distribute verbatim copies of this
	       license document, but changing it is not	allowed.

       The GNU General Public License is a free, copyleft license for software
       and other kinds of works.

       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.

       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.

       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.

       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

       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.

       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.

       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

       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.

       The precise terms and conditions	for copying, distribution and
       modification follow.

       0. Definitions.
	   "This License" refers to version 3 of the GNU General Public

	   "Copyright" also means copyright-like laws that apply to other
	   kinds of works, such	as semiconductor masks.

	   "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.

	   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.

	   A "covered work" means either the unmodified	Program	or a work
	   based on the	Program.

	   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

	   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

	   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

       1. Source Code.
	   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.

	   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

	   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.

	   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.

	   The Corresponding Source need not include anything that users can
	   regenerate automatically from other parts of	the Corresponding

	   The Corresponding Source for	a work in source code form is that
	   same	work.

       2. Basic	Permissions.
	   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.

	   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.

	   Conveying under any other circumstances is permitted	solely under
	   the conditions stated below.	 Sublicensing is not allowed; section
	   10 makes it unnecessary.

       3. Protecting Users' Legal Rights From Anti-Circumvention Law.
	   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.

	   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.

       4. Conveying Verbatim Copies.
	   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.

	   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.

       5. Conveying Modified Source Versions.
	   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

	   a.  The work	must carry prominent notices stating that you modified
	       it, and giving a	relevant date.

	   b.  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".

	   c.  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

	   d.  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.

	   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.

       6. Conveying Non-Source Forms.
	   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:

	   a.  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.

	   b.  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

	   c.  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.

	   d.  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.

	   e.  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.

	   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.

	   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.

	   "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.

	   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).

	   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.

	   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.

       7. Additional Terms.
	   "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.

	   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.

	   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

	   a.  Disclaiming warranty or limiting	liability differently from the
	       terms of	sections 15 and	16 of this License; or

	   b.  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

	   c.  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

	   d.  Limiting	the use	for publicity purposes of names	of licensors
	       or authors of the material; or

	   e.  Declining to grant rights under trademark law for use of	some
	       trade names, trademarks,	or service marks; or

	   f.  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.

	   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.

	   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.

	   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.

       8. Termination.
	   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).

	   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.

	   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.

	   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.

       9. Acceptance Not Required for Having Copies.
	   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.

       10. Automatic Licensing of Downstream Recipients.
	   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

	   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

	   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.

       11. Patents.
	   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

	   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.

	   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.

	   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.

	   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.

	   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.

	   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.

	   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.

       12. No Surrender	of Others' Freedom.
	   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.

       13. Use with the	GNU Affero General Public License.
	   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.

       14. Revised Versions of this License.
	   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.

	   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.

	   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.

	   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.

       15. Disclaimer of Warranty.

       16. Limitation of Liability.

       17. Interpretation of Sections 15 and 16.
	   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.

   How to Apply	These Terms to Your New	Programs
       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

       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.

	       <one line to give the program's name and	a brief	idea of	what it	does.>
	       Copyright (C) <year> <name of author>

	       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 3 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
	       General Public License for more details.

	       You should have received	a copy of the GNU General Public License
	       along with this program.	 If not, see <>.

       Also add	information on how to contact you by electronic	and paper

       If the program does terminal interaction, make it output	a short	notice
       like this when it starts	in an interactive mode:

	       <program> Copyright (C) <year> <name of author>
	       This program 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.

       The hypothetical	commands show w	and show c should show the appropriate
       parts of	the General Public License.  Of	course,	your program's
       commands	might be different; for	a GUI interface, you would use an
       "about box".

       You should also get your	employer (if you work as a programmer) or
       school, if any, to sign a "copyright disclaimer"	for the	program, if
       necessary.  For more information	on this, and how to apply and follow
       the GNU GPL, see	<>.

       The GNU 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.  But first,
       please read <>.

       gfdl(7),	fsf-funding(7).

       Copyright (c) 2007 Free Software	Foundation, Inc.

       Everyone	is permitted to	copy and distribute verbatim copies of this
       license document, but changing it is not	allowed.
