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