                    GNU AFFERO GENERAL PUBLIC LICENSE
                       Version 3, 19 November 2007
 .
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 .
                            Preamble
 .
  The GNU Affero General Public License is a free, copyleft license
 for software and other kinds of works, specifically designed to ensure
 cooperation with the community in the case of network server software.
 .
  The licenses for most software and other practical works are
 designed to take away your freedom to share and change the works.  By
 contrast, our General Public Licenses are intended to guarantee your
 freedom to share and change all versions of a program--to make sure it
 remains free software for all its users.
 .
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 .
  Developers that use our General Public Licenses protect your rights
 with two steps: (1) assert copyright on the software, and (2) offer
 you this License which gives you legal permission to copy, distribute
 and/or modify the software.
 .
  A secondary benefit of defending all users\' freedom is that
 improvements made in alternate versions of the program, if they
 receive widespread use, become available for other developers to
 incorporate.  Many developers of free software are heartened and
 encouraged by the resulting cooperation.  However, in the case of
 software used on network servers, this result may fail to come about.
 The GNU General Public License permits making a modified version and
 letting the public access it on a server without ever releasing its
 source code to the public.
 .
  The GNU Affero General Public License is designed specifically to
 ensure that, in such cases, the modified source code becomes available
 to the community.  It requires the operator of a network server to
 provide the source code of the modified version running there to the
 users of that server.  Therefore, public use of a modified version, on
 a publicly accessible server, gives the public access to the source
 code of the modified version.
 .
  An older license, called the Affero General Public License and
 published by Affero, was designed to accomplish similar goals.  This is
 a different license, not a version of the Affero GPL, but Affero has
 released a new version of the Affero GPL which permits relicensing under
 this license.
 .
  The precise terms and conditions for copying, distribution and
 modification follow.
 .
                       TERMS AND CONDITIONS
 .
  0. Definitions.
 .
  "This License" refers to version 3 of the GNU Affero General Public
 License.
 .
  "Copyright" also means copyright-like laws that apply to other kinds
 of works, such as semiconductor masks.
 .
  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.
 .
  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
 .
  A "covered work" means either the unmodified Program or a work based
 on the Program.
 .
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
 .
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
 .
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
 .
  1. Source Code.
 .
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
 .
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
 .
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
 .
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work\'s
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
 .
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
 .
  The Corresponding Source for a work in source code form is that
 same work.
 .
  2. Basic Permissions.
 .
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
 .
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
 .
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
 .
  3. Protecting Users\' Legal Rights From Anti-Circumvention Law.
 .
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
 .
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work\'s
 users, your or third parties\' legal rights to forbid circumvention of
 technological measures.
 .
  4. Conveying Verbatim Copies.
 .
  You may convey verbatim copies of the Program\'s source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
 .
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
 .
  5. Conveying Modified Source Versions.
 .
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
 .
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
 .
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
 .
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
 .
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
 .
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation\'s users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
 .
  6. Conveying Non-Source Forms.
 .
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
 .
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
 .
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
 .
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
 .
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
 .
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
 .
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
 .
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
 .
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
 .
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
 .
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
 .
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
 .
  7. Additional Terms.
 .
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
 .
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
 .
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
 .
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
 .
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
 .
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
 .
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
 .
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
 .
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
 .
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further restriction,
 you may remove that term.  If a license document contains a further
 restriction but permits relicensing or conveying under this License, you
 may add to a covered work material governed by the terms of that license
 document, provided that the further restriction does not survive such
 relicensing or conveying.
 .
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
 .
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
 .
  8. Termination.
 .
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
 .
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
 .
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
 .
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
 .
  9. Acceptance Not Required for Having Copies.
 .
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
 .
  10. Automatic Licensing of Downstream Recipients.
 .
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
 .
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party\'s predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
 .
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
 .
  11. Patents.
 .
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor\'s "contributor version".
 .
  A contributor\'s "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
 .
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor\'s essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
 .
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
 .
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient\'s use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
 .
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
 .
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
 .
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
 .
  12. No Surrender of Others\' Freedom.
 .
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
 .
  13. Remote Network Interaction; Use with the GNU General Public License.
 .
  Notwithstanding any other provision of this License, if you modify the
 Program, your modified version must prominently offer all users
 interacting with it remotely through a computer network (if your version
 supports such interaction) an opportunity to receive the Corresponding
 Source of your version by providing access to the Corresponding Source
 from a network server at no charge, through some standard or customary
 means of facilitating copying of software.  This Corresponding Source
 shall include the Corresponding Source for any work covered by version 3
 of the GNU General Public License that is incorporated pursuant to the
 following paragraph.
 .
  Notwithstanding any other provision of this License, you have permission
 to link or combine any covered work with a work licensed under version 3
 of the GNU General Public License into a single combined work, and to
 convey the resulting work.  The terms of this License will continue to
 apply to the part which is the covered work, but the work with which it is
 combined will remain governed by version 3 of the GNU General Public
 License.
 .
  14. Revised Versions of this License.
 .
  The Free Software Foundation may publish revised and/or new versions of
 the GNU Affero General Public License from time to time.  Such new
 versions will be similar in spirit to the present version, but may differ
 in detail to address new problems or concerns.
 .
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU Affero
 General Public License "or any later version" applies to it, you have
 the option of following the terms and conditions either of that
 numbered version or of any later version published by the Free
 Software Foundation.  If the Program does not specify a version number
 of the GNU Affero General Public License, you may choose any version
 ever published by the Free Software Foundation.
 .
  If the Program specifies that a proxy can decide which future
 versions of the GNU Affero General Public License can be used, that
 proxy\'s public statement of acceptance of a version permanently
 authorizes you to choose that version for the Program.
 .
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
 .
  15. Disclaimer of Warranty.
 .
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 .
  16. Limitation of Liability.
 .
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
 .
  17. Interpretation of Sections 15 and 16.
 .
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
 .
                       END OF TERMS AND CONDITIONS
 .
              How to Apply These Terms to Your New Programs
 .
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
 .
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
 .
    <one line to give the program\'s name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
 .
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU Affero General Public License as
    published by the Free Software Foundation, either version 3 of the
    License, or (at your option) any later version.
 .
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU Affero General Public License for more details.
 .
    You should have received a copy of the GNU Affero General Public License
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
 .
 Also add information on how to contact you by electronic and paper mail.
 .
  If your software can interact with users remotely through a computer
 network, you should also make sure that it provides a way for users to
 get its source.  For example, if your program is a web application, its
 interface could display a "Source" link that leads users to an archive
 of the code.  There are many ways you could offer source, and different
 solutions will be better for different programs; see section 13 for the
 specific requirements.
 .
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU AGPL, see
 <http://www.gnu.org/licenses/>.

 Preamble
 ********
 .
 This license establishes the terms under which a given free software
 Package may be copied, modified, distributed, and\/or redistributed.  The
 intent is that the Copyright Holder maintains some artistic control over
 the development of that Package while still keeping the Package
 available as open source and free software.
 .
 You are always permitted to make arrangements wholly outside of this
 license directly with the Copyright Holder of a given Package.  If the
 terms of this license do not permit the full use that you propose to
 make of the Package, you should contact the Copyright Holder and seek a
 different licensing arrangement.
 .
 Definitions
 ***********
 .
 "Copyright Holder" means the individual(s) or organization(s) named in
 the copyright notice for the entire Package.
 .
 "Contributor" means any party that has contributed code or other
 material to the Package, in accordance with the Copyright Holder\'s
 procedures.
 .
 "You" and "your" means any person who would like to copy, distribute, or
 modify the Package.
 .
 "Package" means the collection of files distributed by the Copyright
 Holder, and derivatives of that collection and\/or of those files.  A
 given Package may consist of either the Standard Version, or a Modified
 Version.
 .
 "Distribute" means providing a copy of the Package or making it
 accessible to anyone else, or in the case of a company or organization,
 to others outside of your company or organization.
 .
 "Distributor Fee" means any fee that you charge for Distributing this
 Package or providing support for this Package to another party.  It does
 not mean licensing fees.
 .
 "Standard Version" refers to the Package if it has not been modified, or
 has been modified only in ways explicitly requested by the Copyright
 Holder.
 .
 "Modified Version" means the Package, if it has been changed, and such
 changes were not explicitly requested by the Copyright Holder.
 .
 "Original License" means this Artistic License as Distributed with the
 Standard Version of the Package, in its current version or as it may be
 modified by The Perl Foundation in the future.
 .
 "Source" form means the source code, documentation source, and
 configuration files for the Package.
 .
 "Compiled" form means the compiled bytecode, object code, binary, or any
 other form resulting from mechanical transformation or translation of
 the Source form.
 .
 Permission for Use and Modification Without Distribution
 ********************************************************
 .
 (1) You are permitted to use the Standard Version and create and use
 Modified Versions for any purpose without restriction, provided that you
 do not Distribute the Modified Version.
 .
 Permissions for Redistribution of the Standard Version
 ******************************************************
 .
 (2) You may Distribute verbatim copies of the Source form of the
 Standard Version of this Package in any medium without restriction,
 either gratis or for a Distributor Fee, provided that you duplicate all
 of the original copyright notices and associated disclaimers.  At your
 discretion, such verbatim copies may or may not include a Compiled form
 of the Package.
 .
 (3) You may apply any bug fixes, portability changes, and other
 modifications made available from the Copyright Holder.  The resulting
 Package will still be considered the Standard Version, and as such will
 be subject to the Original License.
 .
 Distribution of Modified Versions of the Package as Source
 **********************************************************
 .
 (4) You may Distribute your Modified Version as Source (either gratis or
 for a Distributor Fee, and with or without a Compiled form of the
 Modified Version) provided that you clearly document how it differs from
 the Standard Version, including, but not limited to, documenting any
 non-standard features, executables, or modules, and provided that you do
 at least ONE of the following:
 .
 (a) make the Modified Version available to the Copyright Holder of the
 Standard Version, under the Original License, so that the Copyright
 Holder may include your modifications in the Standard Version.
 .
 (b) ensure that installation of your Modified Version does not prevent
 the user installing or running the Standard Version.  In addition, the
 Modified Version must bear a name that is different from the name of the
 Standard Version.
 .
 (c) allow anyone who receives a copy of the Modified Version to make the
 Source form of the Modified Version available to others under
 .
 (i) the Original License or
 .
 (ii) a license that permits the licensee to freely copy, modify and
 redistribute the Modified Version using the same licensing terms that
 apply to the copy that the licensee received, and requires that the
 Source form of the Modified Version, and of any works derived from it,
 be made freely available in that license fees are prohibited but
 Distributor Fees are allowed.
 .
 Distribution of Compiled Forms of the Standard Version or Modified
 ******************************************************************
 Versions without the Source
 ***************************
 .
 (5) You may Distribute Compiled forms of the Standard Version without
 the Source, provided that you include complete instructions on how to
 get the Source of the Standard Version.  Such instructions must be valid
 at the time of your distribution.  If these instructions, at any time
 while you are carrying out such distribution, become invalid, you must
 provide new instructions on demand or cease further distribution.  If
 you provide valid instructions or cease distribution within thirty days
 after you become aware that the instructions are invalid, then you do
 not forfeit any of your rights under this license.
 .
 (6) You may Distribute a Modified Version in Compiled form without the
 Source, provided that you comply with Section 4 with respect to the
 Source of the Modified Version.
 .
 Aggregating or Linking the Package
 **********************************
 .
 (7) You may aggregate the Package (either the Standard Version or
 Modified Version) with other packages and Distribute the resulting
 aggregation provided that you do not charge a licensing fee for the
 Package.  Distributor Fees are permitted, and licensing fees for other
 components in the aggregation are permitted.  The terms of this license
 apply to the use and Distribution of the Standard or Modified Versions
 as included in the aggregation.
 .
 (8) You are permitted to link Modified and Standard Versions with other
 works, to embed the Package in a larger work of your own, or to build
 stand-alone binary or bytecode versions of applications that include the
 Package, and Distribute the result without restriction, provided the
 result does not expose a direct interface to the Package.
 .
 Items That are Not Considered Part of a Modified Version
 ********************************************************
 .
 (9) Works (including, but not limited to, modules and scripts) that
 merely extend or make use of the Package, do not, by themselves, cause
 the Package to be a Modified Version.  In addition, such works are not
 considered parts of the Package itself, and are not subject to the terms
 of this license.
 .
 General Provisions
 ******************
 .
 (10) Any use, modification, and distribution of the Standard or Modified
 Versions is governed by this Artistic License.  By using, modifying or
 distributing the Package, you accept this license.  Do not use, modify,
 or distribute the Package, if you do not accept this license.
 .
 (11) If your Modified Version has been derived from a Modified Version
 made by someone other than you, you are nevertheless required to ensure
 that your Modified Version complies with the requirements of this
 license.
 .
 (12) This license does not grant you the right to use any trademark,
 service mark, tradename, or logo of the Copyright Holder.
 .
 (13) This license includes the non-exclusive, worldwide, free-of-charge
 patent license to make, have made, use, offer to sell, sell, import and
 otherwise transfer the Package with respect to any patent claims
 licensable by the Copyright Holder that are necessarily infringed by the
 Package.  If you institute patent litigation (including a cross-claim or
 counterclaim) against any party alleging that the Package constitutes
 direct or contributory patent infringement, then this Artistic License
 to you shall terminate on the date that such litigation is filed.
 .
 (14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT
 HOLDER AND CONTRIBUTORS "AS IS\' AND WITHOUT ANY EXPRESS OR IMPLIED

 Statement of Purpose
 .
 The laws of most jurisdictions throughout the world automatically confer
 exclusive Copyright and Related Rights (defined below) upon the creator and
 subsequent owner(s) (each and all, an "owner") of an original work of
 authorship and/or a database (each, a "Work").
 .
 Certain owners wish to permanently relinquish those rights to a Work for the
 purpose of contributing to a commons of creative, cultural and scientific works
 ("Commons") that the public can reliably and without fear of later claims of
 infringement build upon, modify, incorporate in other works, reuse and
 redistribute as freely as possible in any form whatsoever and for any purposes,
 including without limitation commercial purposes. These owners may contribute
 to the Commons to promote the ideal of a free culture and the further
 production of creative, cultural and scientific works, or to gain reputation or
 greater distribution for their Work in part through the use and efforts of
 others.
 .
 For these and/or other purposes and motivations, and without any expectation of
 additional consideration or compensation, the person associating CC0 with a
 Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
 and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and
 publicly distribute the Work under its terms, with knowledge of his or her
 Copyright and Related Rights in the Work and the meaning and intended legal
 effect of CC0 on those rights.
 .
 1. Copyright and Related Rights. A Work made available under CC0 may be
 protected by copyright and related or neighboring rights ("Copyright and
 Related Rights"). Copyright and Related Rights include, but are not limited to,
 the following:
 .
  i. the right to reproduce, adapt, distribute, perform, display, communicate,
     and translate a Work;
 ii. moral rights retained by the original author(s) and/or performer(s);
 iii. publicity and privacy rights pertaining to a person\'s image or likeness
     depicted in a Work;
 iv. rights protecting against unfair competition in regards to a Work, subject
     to the limitations in paragraph 4(a), below;
  v. rights protecting the extraction, dissemination, use and reuse of data in a
     Work;
 vi. database rights (such as those arising under Directive 96/9/EC of the
     European Parliament and of the Council of 11 March 1996 on the legal
     protection of databases, and under any national implementation thereof,
     including any amended or successor version of such directive); and
 vii. other similar, equivalent or corresponding rights throughout the world
     based on applicable law or treaty, and any national implementations
     thereof.
 .
 2. Waiver. To the greatest extent permitted by, but not in contravention of,
 applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
 unconditionally waives, abandons, and surrenders all of Affirmer\'s Copyright
 and Related Rights and associated claims and causes of action, whether now
 known or unknown (including existing as well as future claims and causes of
 action), in the Work (i) in all territories worldwide, (ii) for the maximum
 duration provided by applicable law or treaty (including future time
 extensions), (iii) in any current or future medium and for any number of
 copies, and (iv) for any purpose whatsoever, including without limitation
 commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes
 the Waiver for the benefit of each member of the public at large and to the
 detriment of Affirmer\'s heirs and successors, fully intending that such Waiver
 shall not be subject to revocation, rescission, cancellation, termination, or
 any other legal or equitable action to disrupt the quiet enjoyment of the Work
 by the public as contemplated by Affirmer\'s express Statement of Purpose.
 .
 3. Public License Fallback. Should any part of the Waiver for any reason be
 judged legally invalid or ineffective under applicable law, then the Waiver
 shall be preserved to the maximum extent permitted taking into account
 Affirmer\'s express Statement of Purpose. In addition, to the extent the Waiver
 is so judged Affirmer hereby grants to each affected person a royalty-free, non
 transferable, non sublicensable, non exclusive, irrevocable and unconditional
 license to exercise Affirmer\'s Copyright and Related Rights in the Work (i) in
 all territories worldwide, (ii) for the maximum duration provided by applicable
 law or treaty (including future time extensions), (iii) in any current or
 future medium and for any number of copies, and (iv) for any purpose
 whatsoever, including without limitation commercial, advertising or promotional
 purposes (the "License"). The License shall be deemed effective as of the date
 CC0 was applied by Affirmer to the Work. Should any part of the License for any
 reason be judged legally invalid or ineffective under applicable law, such
 partial invalidity or ineffectiveness shall not invalidate the remainder of the
 License, and in such case Affirmer hereby affirms that he or she will not (i)
 exercise any of his or her remaining Copyright and Related Rights in the Work
 or (ii) assert any associated claims and causes of action with respect to the
 Work, in either case contrary to Affirmer\'s express Statement of Purpose.
 .
 4. Limitations and Disclaimers.
 .
  a. No trademark or patent rights held by Affirmer are waived, abandoned,
     surrendered, licensed or otherwise affected by this document.
  b. Affirmer offers the Work as-is and makes no representations or warranties
     of any kind concerning the Work, express, implied, statutory or otherwise,
     including without limitation warranties of title, merchantability, fitness
     for a particular purpose, non infringement, or the absence of latent or
     other defects, accuracy, or the present or absence of errors, whether or
     not discoverable, all to the greatest extent permissible under applicable
     law.
  c. Affirmer disclaims responsibility for clearing rights of other persons that
     may apply to the Work or any use thereof, including without limitation any
     person\'s Copyright and Related Rights in the Work. Further, Affirmer
     disclaims responsibility for obtaining any necessary consents, permissions
     or other rights required for any use of the Work.
  d. Affirmer understands and acknowledges that Creative Commons is not a party
     to this document and has no duty or obligation with respect to this CC0 or
     use of the Work.

dh-make-R - Generates a debian/ directory skeleton for R packages

=head1 SYNOPSIS

dh-make-R [options]

 Options:
    --help
    --repo REPO          Override R repository detection
    --tests TEST1,TEST2  Generate autopkgtest templates

=head1 OPTIONS

=over 8

=item B<--help>

Print this help message.

=item B<--repo>

Set the R repository (used in the package name), overriding automatic detection.

=item B<--tests>

Comma-separated list of test templates to generate. Understood values are
"generic" (run tests/*.R), "run-unit-test" (installs tests as documentation,
can be run outside autopkgtest), "bioc" (runs BiocGenerics::testPackage) and
"vignette" (attempts to rebuild documentation).

=back

=head1 DESCRIPTION

B<dh-make-R> should be run from the root of an unpacked R tarball (ie, the
directory containing DESCRIPTION). Values from this are used to generate
default control, copyright, rules, source/format and watch files.
