pavone@467:                     GNU GENERAL PUBLIC LICENSE
pavone@467:                        Version 3, 29 June 2007
pavone@467: 
pavone@467:  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
pavone@467:  Everyone is permitted to copy and distribute verbatim copies
pavone@467:  of this license document, but changing it is not allowed.
pavone@467: 
pavone@467:                             Preamble
pavone@467: 
pavone@467:   The GNU General Public License is a free, copyleft license for
pavone@467: software and other kinds of works.
pavone@467: 
pavone@467:   The licenses for most software and other practical works are designed
pavone@467: to take away your freedom to share and change the works.  By contrast,
pavone@467: the GNU General Public License is intended to guarantee your freedom to
pavone@467: share and change all versions of a program--to make sure it remains free
pavone@467: software for all its users.  We, the Free Software Foundation, use the
pavone@467: GNU General Public License for most of our software; it applies also to
pavone@467: any other work released this way by its authors.  You can apply it to
pavone@467: your programs, too.
pavone@467: 
pavone@467:   When we speak of free software, we are referring to freedom, not
pavone@467: price.  Our General Public Licenses are designed to make sure that you
pavone@467: have the freedom to distribute copies of free software (and charge for
pavone@467: them if you wish), that you receive source code or can get it if you
pavone@467: want it, that you can change the software or use pieces of it in new
pavone@467: free programs, and that you know you can do these things.
pavone@467: 
pavone@467:   To protect your rights, we need to prevent others from denying you
pavone@467: these rights or asking you to surrender the rights.  Therefore, you have
pavone@467: certain responsibilities if you distribute copies of the software, or if
pavone@467: you modify it: responsibilities to respect the freedom of others.
pavone@467: 
pavone@467:   For example, if you distribute copies of such a program, whether
pavone@467: gratis or for a fee, you must pass on to the recipients the same
pavone@467: freedoms that you received.  You must make sure that they, too, receive
pavone@467: or can get the source code.  And you must show them these terms so they
pavone@467: know their rights.
pavone@467: 
pavone@467:   Developers that use the GNU GPL protect your rights with two steps:
pavone@467: (1) assert copyright on the software, and (2) offer you this License
pavone@467: giving you legal permission to copy, distribute and/or modify it.
pavone@467: 
pavone@467:   For the developers' and authors' protection, the GPL clearly explains
pavone@467: that there is no warranty for this free software.  For both users' and
pavone@467: authors' sake, the GPL requires that modified versions be marked as
pavone@467: changed, so that their problems will not be attributed erroneously to
pavone@467: authors of previous versions.
pavone@467: 
pavone@467:   Some devices are designed to deny users access to install or run
pavone@467: modified versions of the software inside them, although the manufacturer
pavone@467: can do so.  This is fundamentally incompatible with the aim of
pavone@467: protecting users' freedom to change the software.  The systematic
pavone@467: pattern of such abuse occurs in the area of products for individuals to
pavone@467: use, which is precisely where it is most unacceptable.  Therefore, we
pavone@467: have designed this version of the GPL to prohibit the practice for those
pavone@467: products.  If such problems arise substantially in other domains, we
pavone@467: stand ready to extend this provision to those domains in future versions
pavone@467: of the GPL, as needed to protect the freedom of users.
pavone@467: 
pavone@467:   Finally, every program is threatened constantly by software patents.
pavone@467: States should not allow patents to restrict development and use of
pavone@467: software on general-purpose computers, but in those that do, we wish to
pavone@467: avoid the special danger that patents applied to a free program could
pavone@467: make it effectively proprietary.  To prevent this, the GPL assures that
pavone@467: patents cannot be used to render the program non-free.
pavone@467: 
pavone@467:   The precise terms and conditions for copying, distribution and
pavone@467: modification follow.
pavone@467: 
pavone@467:                        TERMS AND CONDITIONS
pavone@467: 
pavone@467:   0. Definitions.
pavone@467: 
pavone@467:   "This License" refers to version 3 of the GNU General Public License.
pavone@467: 
pavone@467:   "Copyright" also means copyright-like laws that apply to other kinds of
pavone@467: works, such as semiconductor masks.
pavone@467: 
pavone@467:   "The Program" refers to any copyrightable work licensed under this
pavone@467: License.  Each licensee is addressed as "you".  "Licensees" and
pavone@467: "recipients" may be individuals or organizations.
pavone@467: 
pavone@467:   To "modify" a work means to copy from or adapt all or part of the work
pavone@467: in a fashion requiring copyright permission, other than the making of an
pavone@467: exact copy.  The resulting work is called a "modified version" of the
pavone@467: earlier work or a work "based on" the earlier work.
pavone@467: 
pavone@467:   A "covered work" means either the unmodified Program or a work based
pavone@467: on the Program.
pavone@467: 
pavone@467:   To "propagate" a work means to do anything with it that, without
pavone@467: permission, would make you directly or secondarily liable for
pavone@467: infringement under applicable copyright law, except executing it on a
pavone@467: computer or modifying a private copy.  Propagation includes copying,
pavone@467: distribution (with or without modification), making available to the
pavone@467: public, and in some countries other activities as well.
pavone@467: 
pavone@467:   To "convey" a work means any kind of propagation that enables other
pavone@467: parties to make or receive copies.  Mere interaction with a user through
pavone@467: a computer network, with no transfer of a copy, is not conveying.
pavone@467: 
pavone@467:   An interactive user interface displays "Appropriate Legal Notices"
pavone@467: to the extent that it includes a convenient and prominently visible
pavone@467: feature that (1) displays an appropriate copyright notice, and (2)
pavone@467: tells the user that there is no warranty for the work (except to the
pavone@467: extent that warranties are provided), that licensees may convey the
pavone@467: work under this License, and how to view a copy of this License.  If
pavone@467: the interface presents a list of user commands or options, such as a
pavone@467: menu, a prominent item in the list meets this criterion.
pavone@467: 
pavone@467:   1. Source Code.
pavone@467: 
pavone@467:   The "source code" for a work means the preferred form of the work
pavone@467: for making modifications to it.  "Object code" means any non-source
pavone@467: form of a work.
pavone@467: 
pavone@467:   A "Standard Interface" means an interface that either is an official
pavone@467: standard defined by a recognized standards body, or, in the case of
pavone@467: interfaces specified for a particular programming language, one that
pavone@467: is widely used among developers working in that language.
pavone@467: 
pavone@467:   The "System Libraries" of an executable work include anything, other
pavone@467: than the work as a whole, that (a) is included in the normal form of
pavone@467: packaging a Major Component, but which is not part of that Major
pavone@467: Component, and (b) serves only to enable use of the work with that
pavone@467: Major Component, or to implement a Standard Interface for which an
pavone@467: implementation is available to the public in source code form.  A
pavone@467: "Major Component", in this context, means a major essential component
pavone@467: (kernel, window system, and so on) of the specific operating system
pavone@467: (if any) on which the executable work runs, or a compiler used to
pavone@467: produce the work, or an object code interpreter used to run it.
pavone@467: 
pavone@467:   The "Corresponding Source" for a work in object code form means all
pavone@467: the source code needed to generate, install, and (for an executable
pavone@467: work) run the object code and to modify the work, including scripts to
pavone@467: control those activities.  However, it does not include the work's
pavone@467: System Libraries, or general-purpose tools or generally available free
pavone@467: programs which are used unmodified in performing those activities but
pavone@467: which are not part of the work.  For example, Corresponding Source
pavone@467: includes interface definition files associated with source files for
pavone@467: the work, and the source code for shared libraries and dynamically
pavone@467: linked subprograms that the work is specifically designed to require,
pavone@467: such as by intimate data communication or control flow between those
pavone@467: subprograms and other parts of the work.
pavone@467: 
pavone@467:   The Corresponding Source need not include anything that users
pavone@467: can regenerate automatically from other parts of the Corresponding
pavone@467: Source.
pavone@467: 
pavone@467:   The Corresponding Source for a work in source code form is that
pavone@467: same work.
pavone@467: 
pavone@467:   2. Basic Permissions.
pavone@467: 
pavone@467:   All rights granted under this License are granted for the term of
pavone@467: copyright on the Program, and are irrevocable provided the stated
pavone@467: conditions are met.  This License explicitly affirms your unlimited
pavone@467: permission to run the unmodified Program.  The output from running a
pavone@467: covered work is covered by this License only if the output, given its
pavone@467: content, constitutes a covered work.  This License acknowledges your
pavone@467: rights of fair use or other equivalent, as provided by copyright law.
pavone@467: 
pavone@467:   You may make, run and propagate covered works that you do not
pavone@467: convey, without conditions so long as your license otherwise remains
pavone@467: in force.  You may convey covered works to others for the sole purpose
pavone@467: of having them make modifications exclusively for you, or provide you
pavone@467: with facilities for running those works, provided that you comply with
pavone@467: the terms of this License in conveying all material for which you do
pavone@467: not control copyright.  Those thus making or running the covered works
pavone@467: for you must do so exclusively on your behalf, under your direction
pavone@467: and control, on terms that prohibit them from making any copies of
pavone@467: your copyrighted material outside their relationship with you.
pavone@467: 
pavone@467:   Conveying under any other circumstances is permitted solely under
pavone@467: the conditions stated below.  Sublicensing is not allowed; section 10
pavone@467: makes it unnecessary.
pavone@467: 
pavone@467:   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
pavone@467: 
pavone@467:   No covered work shall be deemed part of an effective technological
pavone@467: measure under any applicable law fulfilling obligations under article
pavone@467: 11 of the WIPO copyright treaty adopted on 20 December 1996, or
pavone@467: similar laws prohibiting or restricting circumvention of such
pavone@467: measures.
pavone@467: 
pavone@467:   When you convey a covered work, you waive any legal power to forbid
pavone@467: circumvention of technological measures to the extent such circumvention
pavone@467: is effected by exercising rights under this License with respect to
pavone@467: the covered work, and you disclaim any intention to limit operation or
pavone@467: modification of the work as a means of enforcing, against the work's
pavone@467: users, your or third parties' legal rights to forbid circumvention of
pavone@467: technological measures.
pavone@467: 
pavone@467:   4. Conveying Verbatim Copies.
pavone@467: 
pavone@467:   You may convey verbatim copies of the Program's source code as you
pavone@467: receive it, in any medium, provided that you conspicuously and
pavone@467: appropriately publish on each copy an appropriate copyright notice;
pavone@467: keep intact all notices stating that this License and any
pavone@467: non-permissive terms added in accord with section 7 apply to the code;
pavone@467: keep intact all notices of the absence of any warranty; and give all
pavone@467: recipients a copy of this License along with the Program.
pavone@467: 
pavone@467:   You may charge any price or no price for each copy that you convey,
pavone@467: and you may offer support or warranty protection for a fee.
pavone@467: 
pavone@467:   5. Conveying Modified Source Versions.
pavone@467: 
pavone@467:   You may convey a work based on the Program, or the modifications to
pavone@467: produce it from the Program, in the form of source code under the
pavone@467: terms of section 4, provided that you also meet all of these conditions:
pavone@467: 
pavone@467:     a) The work must carry prominent notices stating that you modified
pavone@467:     it, and giving a relevant date.
pavone@467: 
pavone@467:     b) The work must carry prominent notices stating that it is
pavone@467:     released under this License and any conditions added under section
pavone@467:     7.  This requirement modifies the requirement in section 4 to
pavone@467:     "keep intact all notices".
pavone@467: 
pavone@467:     c) You must license the entire work, as a whole, under this
pavone@467:     License to anyone who comes into possession of a copy.  This
pavone@467:     License will therefore apply, along with any applicable section 7
pavone@467:     additional terms, to the whole of the work, and all its parts,
pavone@467:     regardless of how they are packaged.  This License gives no
pavone@467:     permission to license the work in any other way, but it does not
pavone@467:     invalidate such permission if you have separately received it.
pavone@467: 
pavone@467:     d) If the work has interactive user interfaces, each must display
pavone@467:     Appropriate Legal Notices; however, if the Program has interactive
pavone@467:     interfaces that do not display Appropriate Legal Notices, your
pavone@467:     work need not make them do so.
pavone@467: 
pavone@467:   A compilation of a covered work with other separate and independent
pavone@467: works, which are not by their nature extensions of the covered work,
pavone@467: and which are not combined with it such as to form a larger program,
pavone@467: in or on a volume of a storage or distribution medium, is called an
pavone@467: "aggregate" if the compilation and its resulting copyright are not
pavone@467: used to limit the access or legal rights of the compilation's users
pavone@467: beyond what the individual works permit.  Inclusion of a covered work
pavone@467: in an aggregate does not cause this License to apply to the other
pavone@467: parts of the aggregate.
pavone@467: 
pavone@467:   6. Conveying Non-Source Forms.
pavone@467: 
pavone@467:   You may convey a covered work in object code form under the terms
pavone@467: of sections 4 and 5, provided that you also convey the
pavone@467: machine-readable Corresponding Source under the terms of this License,
pavone@467: in one of these ways:
pavone@467: 
pavone@467:     a) Convey the object code in, or embodied in, a physical product
pavone@467:     (including a physical distribution medium), accompanied by the
pavone@467:     Corresponding Source fixed on a durable physical medium
pavone@467:     customarily used for software interchange.
pavone@467: 
pavone@467:     b) Convey the object code in, or embodied in, a physical product
pavone@467:     (including a physical distribution medium), accompanied by a
pavone@467:     written offer, valid for at least three years and valid for as
pavone@467:     long as you offer spare parts or customer support for that product
pavone@467:     model, to give anyone who possesses the object code either (1) a
pavone@467:     copy of the Corresponding Source for all the software in the
pavone@467:     product that is covered by this License, on a durable physical
pavone@467:     medium customarily used for software interchange, for a price no
pavone@467:     more than your reasonable cost of physically performing this
pavone@467:     conveying of source, or (2) access to copy the
pavone@467:     Corresponding Source from a network server at no charge.
pavone@467: 
pavone@467:     c) Convey individual copies of the object code with a copy of the
pavone@467:     written offer to provide the Corresponding Source.  This
pavone@467:     alternative is allowed only occasionally and noncommercially, and
pavone@467:     only if you received the object code with such an offer, in accord
pavone@467:     with subsection 6b.
pavone@467: 
pavone@467:     d) Convey the object code by offering access from a designated
pavone@467:     place (gratis or for a charge), and offer equivalent access to the
pavone@467:     Corresponding Source in the same way through the same place at no
pavone@467:     further charge.  You need not require recipients to copy the
pavone@467:     Corresponding Source along with the object code.  If the place to
pavone@467:     copy the object code is a network server, the Corresponding Source
pavone@467:     may be on a different server (operated by you or a third party)
pavone@467:     that supports equivalent copying facilities, provided you maintain
pavone@467:     clear directions next to the object code saying where to find the
pavone@467:     Corresponding Source.  Regardless of what server hosts the
pavone@467:     Corresponding Source, you remain obligated to ensure that it is
pavone@467:     available for as long as needed to satisfy these requirements.
pavone@467: 
pavone@467:     e) Convey the object code using peer-to-peer transmission, provided
pavone@467:     you inform other peers where the object code and Corresponding
pavone@467:     Source of the work are being offered to the general public at no
pavone@467:     charge under subsection 6d.
pavone@467: 
pavone@467:   A separable portion of the object code, whose source code is excluded
pavone@467: from the Corresponding Source as a System Library, need not be
pavone@467: included in conveying the object code work.
pavone@467: 
pavone@467:   A "User Product" is either (1) a "consumer product", which means any
pavone@467: tangible personal property which is normally used for personal, family,
pavone@467: or household purposes, or (2) anything designed or sold for incorporation
pavone@467: into a dwelling.  In determining whether a product is a consumer product,
pavone@467: doubtful cases shall be resolved in favor of coverage.  For a particular
pavone@467: product received by a particular user, "normally used" refers to a
pavone@467: typical or common use of that class of product, regardless of the status
pavone@467: of the particular user or of the way in which the particular user
pavone@467: actually uses, or expects or is expected to use, the product.  A product
pavone@467: is a consumer product regardless of whether the product has substantial
pavone@467: commercial, industrial or non-consumer uses, unless such uses represent
pavone@467: the only significant mode of use of the product.
pavone@467: 
pavone@467:   "Installation Information" for a User Product means any methods,
pavone@467: procedures, authorization keys, or other information required to install
pavone@467: and execute modified versions of a covered work in that User Product from
pavone@467: a modified version of its Corresponding Source.  The information must
pavone@467: suffice to ensure that the continued functioning of the modified object
pavone@467: code is in no case prevented or interfered with solely because
pavone@467: modification has been made.
pavone@467: 
pavone@467:   If you convey an object code work under this section in, or with, or
pavone@467: specifically for use in, a User Product, and the conveying occurs as
pavone@467: part of a transaction in which the right of possession and use of the
pavone@467: User Product is transferred to the recipient in perpetuity or for a
pavone@467: fixed term (regardless of how the transaction is characterized), the
pavone@467: Corresponding Source conveyed under this section must be accompanied
pavone@467: by the Installation Information.  But this requirement does not apply
pavone@467: if neither you nor any third party retains the ability to install
pavone@467: modified object code on the User Product (for example, the work has
pavone@467: been installed in ROM).
pavone@467: 
pavone@467:   The requirement to provide Installation Information does not include a
pavone@467: requirement to continue to provide support service, warranty, or updates
pavone@467: for a work that has been modified or installed by the recipient, or for
pavone@467: the User Product in which it has been modified or installed.  Access to a
pavone@467: network may be denied when the modification itself materially and
pavone@467: adversely affects the operation of the network or violates the rules and
pavone@467: protocols for communication across the network.
pavone@467: 
pavone@467:   Corresponding Source conveyed, and Installation Information provided,
pavone@467: in accord with this section must be in a format that is publicly
pavone@467: documented (and with an implementation available to the public in
pavone@467: source code form), and must require no special password or key for
pavone@467: unpacking, reading or copying.
pavone@467: 
pavone@467:   7. Additional Terms.
pavone@467: 
pavone@467:   "Additional permissions" are terms that supplement the terms of this
pavone@467: License by making exceptions from one or more of its conditions.
pavone@467: Additional permissions that are applicable to the entire Program shall
pavone@467: be treated as though they were included in this License, to the extent
pavone@467: that they are valid under applicable law.  If additional permissions
pavone@467: apply only to part of the Program, that part may be used separately
pavone@467: under those permissions, but the entire Program remains governed by
pavone@467: this License without regard to the additional permissions.
pavone@467: 
pavone@467:   When you convey a copy of a covered work, you may at your option
pavone@467: remove any additional permissions from that copy, or from any part of
pavone@467: it.  (Additional permissions may be written to require their own
pavone@467: removal in certain cases when you modify the work.)  You may place
pavone@467: additional permissions on material, added by you to a covered work,
pavone@467: for which you have or can give appropriate copyright permission.
pavone@467: 
pavone@467:   Notwithstanding any other provision of this License, for material you
pavone@467: add to a covered work, you may (if authorized by the copyright holders of
pavone@467: that material) supplement the terms of this License with terms:
pavone@467: 
pavone@467:     a) Disclaiming warranty or limiting liability differently from the
pavone@467:     terms of sections 15 and 16 of this License; or
pavone@467: 
pavone@467:     b) Requiring preservation of specified reasonable legal notices or
pavone@467:     author attributions in that material or in the Appropriate Legal
pavone@467:     Notices displayed by works containing it; or
pavone@467: 
pavone@467:     c) Prohibiting misrepresentation of the origin of that material, or
pavone@467:     requiring that modified versions of such material be marked in
pavone@467:     reasonable ways as different from the original version; or
pavone@467: 
pavone@467:     d) Limiting the use for publicity purposes of names of licensors or
pavone@467:     authors of the material; or
pavone@467: 
pavone@467:     e) Declining to grant rights under trademark law for use of some
pavone@467:     trade names, trademarks, or service marks; or
pavone@467: 
pavone@467:     f) Requiring indemnification of licensors and authors of that
pavone@467:     material by anyone who conveys the material (or modified versions of
pavone@467:     it) with contractual assumptions of liability to the recipient, for
pavone@467:     any liability that these contractual assumptions directly impose on
pavone@467:     those licensors and authors.
pavone@467: 
pavone@467:   All other non-permissive additional terms are considered "further
pavone@467: restrictions" within the meaning of section 10.  If the Program as you
pavone@467: received it, or any part of it, contains a notice stating that it is
pavone@467: governed by this License along with a term that is a further
pavone@467: restriction, you may remove that term.  If a license document contains
pavone@467: a further restriction but permits relicensing or conveying under this
pavone@467: License, you may add to a covered work material governed by the terms
pavone@467: of that license document, provided that the further restriction does
pavone@467: not survive such relicensing or conveying.
pavone@467: 
pavone@467:   If you add terms to a covered work in accord with this section, you
pavone@467: must place, in the relevant source files, a statement of the
pavone@467: additional terms that apply to those files, or a notice indicating
pavone@467: where to find the applicable terms.
pavone@467: 
pavone@467:   Additional terms, permissive or non-permissive, may be stated in the
pavone@467: form of a separately written license, or stated as exceptions;
pavone@467: the above requirements apply either way.
pavone@467: 
pavone@467:   8. Termination.
pavone@467: 
pavone@467:   You may not propagate or modify a covered work except as expressly
pavone@467: provided under this License.  Any attempt otherwise to propagate or
pavone@467: modify it is void, and will automatically terminate your rights under
pavone@467: this License (including any patent licenses granted under the third
pavone@467: paragraph of section 11).
pavone@467: 
pavone@467:   However, if you cease all violation of this License, then your
pavone@467: license from a particular copyright holder is reinstated (a)
pavone@467: provisionally, unless and until the copyright holder explicitly and
pavone@467: finally terminates your license, and (b) permanently, if the copyright
pavone@467: holder fails to notify you of the violation by some reasonable means
pavone@467: prior to 60 days after the cessation.
pavone@467: 
pavone@467:   Moreover, your license from a particular copyright holder is
pavone@467: reinstated permanently if the copyright holder notifies you of the
pavone@467: violation by some reasonable means, this is the first time you have
pavone@467: received notice of violation of this License (for any work) from that
pavone@467: copyright holder, and you cure the violation prior to 30 days after
pavone@467: your receipt of the notice.
pavone@467: 
pavone@467:   Termination of your rights under this section does not terminate the
pavone@467: licenses of parties who have received copies or rights from you under
pavone@467: this License.  If your rights have been terminated and not permanently
pavone@467: reinstated, you do not qualify to receive new licenses for the same
pavone@467: material under section 10.
pavone@467: 
pavone@467:   9. Acceptance Not Required for Having Copies.
pavone@467: 
pavone@467:   You are not required to accept this License in order to receive or
pavone@467: run a copy of the Program.  Ancillary propagation of a covered work
pavone@467: occurring solely as a consequence of using peer-to-peer transmission
pavone@467: to receive a copy likewise does not require acceptance.  However,
pavone@467: nothing other than this License grants you permission to propagate or
pavone@467: modify any covered work.  These actions infringe copyright if you do
pavone@467: not accept this License.  Therefore, by modifying or propagating a
pavone@467: covered work, you indicate your acceptance of this License to do so.
pavone@467: 
pavone@467:   10. Automatic Licensing of Downstream Recipients.
pavone@467: 
pavone@467:   Each time you convey a covered work, the recipient automatically
pavone@467: receives a license from the original licensors, to run, modify and
pavone@467: propagate that work, subject to this License.  You are not responsible
pavone@467: for enforcing compliance by third parties with this License.
pavone@467: 
pavone@467:   An "entity transaction" is a transaction transferring control of an
pavone@467: organization, or substantially all assets of one, or subdividing an
pavone@467: organization, or merging organizations.  If propagation of a covered
pavone@467: work results from an entity transaction, each party to that
pavone@467: transaction who receives a copy of the work also receives whatever
pavone@467: licenses to the work the party's predecessor in interest had or could
pavone@467: give under the previous paragraph, plus a right to possession of the
pavone@467: Corresponding Source of the work from the predecessor in interest, if
pavone@467: the predecessor has it or can get it with reasonable efforts.
pavone@467: 
pavone@467:   You may not impose any further restrictions on the exercise of the
pavone@467: rights granted or affirmed under this License.  For example, you may
pavone@467: not impose a license fee, royalty, or other charge for exercise of
pavone@467: rights granted under this License, and you may not initiate litigation
pavone@467: (including a cross-claim or counterclaim in a lawsuit) alleging that
pavone@467: any patent claim is infringed by making, using, selling, offering for
pavone@467: sale, or importing the Program or any portion of it.
pavone@467: 
pavone@467:   11. Patents.
pavone@467: 
pavone@467:   A "contributor" is a copyright holder who authorizes use under this
pavone@467: License of the Program or a work on which the Program is based.  The
pavone@467: work thus licensed is called the contributor's "contributor version".
pavone@467: 
pavone@467:   A contributor's "essential patent claims" are all patent claims
pavone@467: owned or controlled by the contributor, whether already acquired or
pavone@467: hereafter acquired, that would be infringed by some manner, permitted
pavone@467: by this License, of making, using, or selling its contributor version,
pavone@467: but do not include claims that would be infringed only as a
pavone@467: consequence of further modification of the contributor version.  For
pavone@467: purposes of this definition, "control" includes the right to grant
pavone@467: patent sublicenses in a manner consistent with the requirements of
pavone@467: this License.
pavone@467: 
pavone@467:   Each contributor grants you a non-exclusive, worldwide, royalty-free
pavone@467: patent license under the contributor's essential patent claims, to
pavone@467: make, use, sell, offer for sale, import and otherwise run, modify and
pavone@467: propagate the contents of its contributor version.
pavone@467: 
pavone@467:   In the following three paragraphs, a "patent license" is any express
pavone@467: agreement or commitment, however denominated, not to enforce a patent
pavone@467: (such as an express permission to practice a patent or covenant not to
pavone@467: sue for patent infringement).  To "grant" such a patent license to a
pavone@467: party means to make such an agreement or commitment not to enforce a
pavone@467: patent against the party.
pavone@467: 
pavone@467:   If you convey a covered work, knowingly relying on a patent license,
pavone@467: and the Corresponding Source of the work is not available for anyone
pavone@467: to copy, free of charge and under the terms of this License, through a
pavone@467: publicly available network server or other readily accessible means,
pavone@467: then you must either (1) cause the Corresponding Source to be so
pavone@467: available, or (2) arrange to deprive yourself of the benefit of the
pavone@467: patent license for this particular work, or (3) arrange, in a manner
pavone@467: consistent with the requirements of this License, to extend the patent
pavone@467: license to downstream recipients.  "Knowingly relying" means you have
pavone@467: actual knowledge that, but for the patent license, your conveying the
pavone@467: covered work in a country, or your recipient's use of the covered work
pavone@467: in a country, would infringe one or more identifiable patents in that
pavone@467: country that you have reason to believe are valid.
pavone@467: 
pavone@467:   If, pursuant to or in connection with a single transaction or
pavone@467: arrangement, you convey, or propagate by procuring conveyance of, a
pavone@467: covered work, and grant a patent license to some of the parties
pavone@467: receiving the covered work authorizing them to use, propagate, modify
pavone@467: or convey a specific copy of the covered work, then the patent license
pavone@467: you grant is automatically extended to all recipients of the covered
pavone@467: work and works based on it.
pavone@467: 
pavone@467:   A patent license is "discriminatory" if it does not include within
pavone@467: the scope of its coverage, prohibits the exercise of, or is
pavone@467: conditioned on the non-exercise of one or more of the rights that are
pavone@467: specifically granted under this License.  You may not convey a covered
pavone@467: work if you are a party to an arrangement with a third party that is
pavone@467: in the business of distributing software, under which you make payment
pavone@467: to the third party based on the extent of your activity of conveying
pavone@467: the work, and under which the third party grants, to any of the
pavone@467: parties who would receive the covered work from you, a discriminatory
pavone@467: patent license (a) in connection with copies of the covered work
pavone@467: conveyed by you (or copies made from those copies), or (b) primarily
pavone@467: for and in connection with specific products or compilations that
pavone@467: contain the covered work, unless you entered into that arrangement,
pavone@467: or that patent license was granted, prior to 28 March 2007.
pavone@467: 
pavone@467:   Nothing in this License shall be construed as excluding or limiting
pavone@467: any implied license or other defenses to infringement that may
pavone@467: otherwise be available to you under applicable patent law.
pavone@467: 
pavone@467:   12. No Surrender of Others' Freedom.
pavone@467: 
pavone@467:   If conditions are imposed on you (whether by court order, agreement or
pavone@467: otherwise) that contradict the conditions of this License, they do not
pavone@467: excuse you from the conditions of this License.  If you cannot convey a
pavone@467: covered work so as to satisfy simultaneously your obligations under this
pavone@467: License and any other pertinent obligations, then as a consequence you may
pavone@467: not convey it at all.  For example, if you agree to terms that obligate you
pavone@467: to collect a royalty for further conveying from those to whom you convey
pavone@467: the Program, the only way you could satisfy both those terms and this
pavone@467: License would be to refrain entirely from conveying the Program.
pavone@467: 
pavone@467:   13. Use with the GNU Affero General Public License.
pavone@467: 
pavone@467:   Notwithstanding any other provision of this License, you have
pavone@467: permission to link or combine any covered work with a work licensed
pavone@467: under version 3 of the GNU Affero General Public License into a single
pavone@467: combined work, and to convey the resulting work.  The terms of this
pavone@467: License will continue to apply to the part which is the covered work,
pavone@467: but the special requirements of the GNU Affero General Public License,
pavone@467: section 13, concerning interaction through a network will apply to the
pavone@467: combination as such.
pavone@467: 
pavone@467:   14. Revised Versions of this License.
pavone@467: 
pavone@467:   The Free Software Foundation may publish revised and/or new versions of
pavone@467: the GNU General Public License from time to time.  Such new versions will
pavone@467: be similar in spirit to the present version, but may differ in detail to
pavone@467: address new problems or concerns.
pavone@467: 
pavone@467:   Each version is given a distinguishing version number.  If the
pavone@467: Program specifies that a certain numbered version of the GNU General
pavone@467: Public License "or any later version" applies to it, you have the
pavone@467: option of following the terms and conditions either of that numbered
pavone@467: version or of any later version published by the Free Software
pavone@467: Foundation.  If the Program does not specify a version number of the
pavone@467: GNU General Public License, you may choose any version ever published
pavone@467: by the Free Software Foundation.
pavone@467: 
pavone@467:   If the Program specifies that a proxy can decide which future
pavone@467: versions of the GNU General Public License can be used, that proxy's
pavone@467: public statement of acceptance of a version permanently authorizes you
pavone@467: to choose that version for the Program.
pavone@467: 
pavone@467:   Later license versions may give you additional or different
pavone@467: permissions.  However, no additional obligations are imposed on any
pavone@467: author or copyright holder as a result of your choosing to follow a
pavone@467: later version.
pavone@467: 
pavone@467:   15. Disclaimer of Warranty.
pavone@467: 
pavone@467:   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
pavone@467: APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
pavone@467: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
pavone@467: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
pavone@467: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
pavone@467: PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
pavone@467: IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
pavone@467: ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
pavone@467: 
pavone@467:   16. Limitation of Liability.
pavone@467: 
pavone@467:   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
pavone@467: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
pavone@467: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
pavone@467: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
pavone@467: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
pavone@467: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
pavone@467: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
pavone@467: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
pavone@467: SUCH DAMAGES.
pavone@467: 
pavone@467:   17. Interpretation of Sections 15 and 16.
pavone@467: 
pavone@467:   If the disclaimer of warranty and limitation of liability provided
pavone@467: above cannot be given local legal effect according to their terms,
pavone@467: reviewing courts shall apply local law that most closely approximates
pavone@467: an absolute waiver of all civil liability in connection with the
pavone@467: Program, unless a warranty or assumption of liability accompanies a
pavone@467: copy of the Program in return for a fee.
pavone@467: 
pavone@467:                      END OF TERMS AND CONDITIONS
pavone@467: 
pavone@467:             How to Apply These Terms to Your New Programs
pavone@467: 
pavone@467:   If you develop a new program, and you want it to be of the greatest
pavone@467: possible use to the public, the best way to achieve this is to make it
pavone@467: free software which everyone can redistribute and change under these terms.
pavone@467: 
pavone@467:   To do so, attach the following notices to the program.  It is safest
pavone@467: to attach them to the start of each source file to most effectively
pavone@467: state the exclusion of warranty; and each file should have at least
pavone@467: the "copyright" line and a pointer to where the full notice is found.
pavone@467: 
pavone@467:     <one line to give the program's name and a brief idea of what it does.>
pavone@467:     Copyright (C) <year>  <name of author>
pavone@467: 
pavone@467:     This program is free software: you can redistribute it and/or modify
pavone@467:     it under the terms of the GNU General Public License as published by
pavone@467:     the Free Software Foundation, either version 3 of the License, or
pavone@467:     (at your option) any later version.
pavone@467: 
pavone@467:     This program is distributed in the hope that it will be useful,
pavone@467:     but WITHOUT ANY WARRANTY; without even the implied warranty of
pavone@467:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
pavone@467:     GNU General Public License for more details.
pavone@467: 
pavone@467:     You should have received a copy of the GNU General Public License
pavone@467:     along with this program.  If not, see <http://www.gnu.org/licenses/>.
pavone@467: 
pavone@467: Also add information on how to contact you by electronic and paper mail.
pavone@467: 
pavone@467:   If the program does terminal interaction, make it output a short
pavone@467: notice like this when it starts in an interactive mode:
pavone@467: 
pavone@467:     <program>  Copyright (C) <year>  <name of author>
pavone@467:     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
pavone@467:     This is free software, and you are welcome to redistribute it
pavone@467:     under certain conditions; type `show c' for details.
pavone@467: 
pavone@467: The hypothetical commands `show w' and `show c' should show the appropriate
pavone@467: parts of the General Public License.  Of course, your program's commands
pavone@467: might be different; for a GUI interface, you would use an "about box".
pavone@467: 
pavone@467:   You should also get your employer (if you work as a programmer) or school,
pavone@467: if any, to sign a "copyright disclaimer" for the program, if necessary.
pavone@467: For more information on this, and how to apply and follow the GNU GPL, see
pavone@467: <http://www.gnu.org/licenses/>.
pavone@467: 
pavone@467:   The GNU General Public License does not permit incorporating your program
pavone@467: into proprietary programs.  If your program is a subroutine library, you
pavone@467: may consider it more useful to permit linking proprietary applications with
pavone@467: the library.  If this is what you want to do, use the GNU Lesser General
pavone@467: Public License instead of this License.  But first, please read
pavone@467: <http://www.gnu.org/philosophy/why-not-lgpl.html>.
