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