+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU 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. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+
+ Copyright (C)
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see .
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ Copyright (C)
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+.

+
+`dnsmeter` is a tool for testing performance of a nameserver and the
+infrastructure around it. It generates DNS queries and sends them via UDP
+to a target nameserver and counts the answers.
+
+Features:
+- payload can be given as a text file or a PCAP file
+- can automatically run different load steps, which can be given as a list or ranges
+- results per load step can be stored in a CSV file
+- sender addresses can be spoofed from a given network or from the addresses found in the PCAP file
+- answers are counted, even if source address is spoofed, if answers get routed back to the load generator
+- round-trip-times are measured (average, min, mix)
+- the amount of DNSSEC queries can be given as percentage of total traffic
+- optimized for high amount of packets, on an Intel(R) Xeon(R) CPU E5-2430 v2 @ 2.50GHz it can generate more than 900.000 packets per second
+- runs on Linux and FreeBSD
+
+## Dependencies
+
+`dnsmeter` requires a couple of libraries beside a normal C++ compiling
+environment with autoconf, automake and libtool.
+
+`dnsmeter` has a non-optional dependency on the PCRE library, `libresolv`
+and PCAP library.
+
+`dnsmeter` also includes [pplib](https://github.com/DNS-OARC/pplib),
+collection of C++ functions and classes, and it has non-optional dependency
+on OpenSSL, bzip2, IDN2 (or IDN1) library and zlib.
+
+To install the dependencies under Debian/Ubuntu:
+```
+apt-get install -y libssl-dev libbz2-dev libidn2-dev zlib1g-dev libpcap-dev libpcre3-dev gettext
+```
+
+NOTE: If your system does not have `libidn2-dev`, please use `libidn11-dev` instead.
+
+To install the dependencies under CentOS (with EPEL enabled):
+```
+yum install -y openssl-devel bzip2-devel libidn2-devel zlib-devel libpcap-devel pcre-devel gettext-devel
+```
+
+NOTE: If your using openSUSE/SLE then bzip2's package is `libbz2-devel`.
+
+To install the dependencies under FreeBSD 10+ using `pkg`:
+```
+pkg install -y openssl libidn2 libpcap pcre gettext
+```
+
+## Building from source tarball
+
+The [source tarball from DNS-OARC](https://www.dns-oarc.net/tools/dnsmeter)
+comes prepared with `configure`:
+
+```
+tar zxvf dnsmeter-version.tar.gz
+cd dnsmeter-version
+./configure [options]
+make
+make install
+```
+
+NOTE: If building fails on FreeBSD, try adding these configure
+options: `--with-extra-cflags="-I /usr/local/include" --with-extra-ldflags="-L/usr/local/lib"`.
+
+## Building from Git repository
+
+If you are building `dnsmeter` from it's Git repository you will first need
+to initiate the Git submodules that exists and later create autoconf/automake
+files, this will require a build environment with autoconf, automake and
+libtool to be installed.
+
+```
+git clone https://github.com/DNS-OARC/dnsmeter.git
+cd dnsmeter
+git submodule update --init
+./autogen.sh
+./configure [options]
+make
+make install
+```
+
+## Usage
+
+Once installed please see `man dnsmeter` for usage.
+
+## Example
+
+Lets assume the following scenario:
+
+- load generator runs on FreeBSD
+- network interface an which the traffic goes out and comes back is `igb0`
+- source IP on the load generator is 192.168.155.20
+- target nameserver has IP 192.168.0.1, port 53
+- we want to spoof the sender address from the network 10.0.0.0/8
+- the payload file is found here: `/home/testdata/payload.txt`
+- the nameserver is running on CentOS and we need to set a route back to the load generator: `ip route add 10.0.0.0/8 via 192.168.155.20`
+- we want to test the following load steps: 30000,40000,45000,50000,100000,150000
+- results should be written to `results.csv`
+- DNSSEC rate should be 70%
+
+This makes the following command:
+
+```
+dnsmeter -p /home/testdata/payload.txt \
+ -r 30000,40000,45000,50000,100000,150000 \
+ -s 10.0.0.0/8 \
+ -z 192.168.0.1:53 \
+ -e igb0 \
+ -d 70 \
+ -c results.csv
+```
+
+In the second example, we want to use a PCAP file as payload and want
+to spoof with the addresses from that file:
+
+```
+dnsmeter -p /home/testdata/pcap.file1 \
+ -r 30000,40000,45000,50000,100000,150000 \
+ -s pcap \
+ -z 192.168.0.1:53 \
+ -e igb0 \
+ -c results_pcap.csv
+```

+# AX_CFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+# AX_CXXFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+# AX_FCFLAGS_WARN_ALL [(shellvar[, default[, action-if-found[, action-if-not-found]]])]
+#
+# DESCRIPTION
+#
+# Specify compiler options that enable most reasonable warnings. For the
+# GNU Compiler Collection (GCC), for example, it will be "-Wall". The
+# result is added to shellvar, one of CFLAGS, CXXFLAGS or FCFLAGS if the
+# first parameter is not specified.
+#
+# Each of these macros accepts the following optional arguments:
+#
+# - $1 - shellvar
+# shell variable to use (CFLAGS, CXXFLAGS or FCFLAGS if not
+# specified, depending on macro)
+#
+# - $2 - default
+# value to use for flags if compiler vendor cannot be determined (by
+# default, "")
+#
+# - $3 - action-if-found
+# action to take if the compiler vendor has been successfully
+# determined (by default, add the appropriate compiler flags to
+# shellvar)
+#
+# - $4 - action-if-not-found
+# action to take if the compiler vendor has not been determined or
+# is unknown (by default, add the default flags, or "" if not
+# specified, to shellvar)
+#
+# These macros use AX_COMPILER_VENDOR to determine which flags should be
+# returned for a given compiler. Not all compilers currently have flags
+# defined for them; patches are welcome. If need be, compiler flags may
+# be made language-dependent: use a construct like the following:
+#
+# [vendor_name], [m4_if(_AC_LANG_PREFIX,[C], VAR="--relevant-c-flags",dnl
+# m4_if(_AC_LANG_PREFIX,[CXX], VAR="--relevant-c++-flags",dnl
+# m4_if(_AC_LANG_PREFIX,[FC], VAR="--relevant-fortran-flags",dnl
+# VAR="$2"; FOUND="no")))],
+#
+# Note: These macros also depend on AX_PREPEND_FLAG.

+# Determine the vendor of the C, C++ or Fortran compiler. The vendor is
+# returned in the cache variable $ax_cv_c_compiler_vendor for C,
+# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for

+# "tcc" (Tiny CC) or "unknown" (if the compiler cannot be determined).
+#
+# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also to link with them as well. For example, you might link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threaded programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+ #
+ # Problem is, this is at odds with the way Automake and most other

+ # flag that is used only in the compilation phase and not in
+ # linking. Such a scenario is extremely rare in practice.
+ #
+ # Even though use of the -pthread flag in linking would only print

+# SYNOPSIS
+#
+# AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+# been defined and thus are available for use. This avoids random issues
+# where a macro isn't expanded. Instead the configure script emits a
+# non-fatal:
+#
+# ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+# It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+# Here's an example:
+#
+# AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])

+%description
+DNSMeter is a tool for testing performance of nameserver and/or
+infrastructure around it.
+It generates dns queries and sends them via UDP to a target nameserver
+and counts the answers.
+
+Features:
+- payload can be given as text file or pcap file
+- can automatically run different load steps, which can be given as
+ list or ranges
+- results per load step can be stored in CSV file
+- sender address can be spoofed from a given network or from pcap file,
+ if payload is a pcap file
+- answers are counted, even if source address is spoofed, if answers get
+ routed back to the load generator
+- roundtrip-times are measured (average, min, mix)
+- amount of DNSSEC queries can be given as percentage of total traffic
+- optimized for high amount of packets. On an Intel(R) Xeon(R) CPU E5-2430
+ v2 @ 2.50GHz it can generate more than 900.000 packets per second

+%changelog
+* Wed Jun 02 2021 Jerry Lundström 1.0.2-1
+- Release 1.0.2
+ * This release fixes an issue with source port being static when only
+ using `-q` to generate traffic from one host/IP. The source port is
+ now randomized for every DNS query.
+ * Other changes is mainly about build system, packages and fixed issues
+ detected by code analysis tools.
+ * Commits:
+ 05000cc Typo, random source port
+ 6a71707 Coverage
+ 1c724ce SonarCloud
+ 0776d20 Badges
+ c274884 LGTM

+* Mon Oct 07 2019 Jerry Lundström 1.0.1-1
+- Release 1.0.1
+ * This release fixes a few minor bugs and a dependency issue which made
+ `dnsmeter` throw an exception when using the `-r` option.
+ * Bugfixes:
+ - Use existing `rtt_avg`, was showing total RTT divided by number of threads
+ - Fix an issue which missed the first 8 bytes of a text payload
+ * Commits:
+ 72197b5 PCAP detect
+ 665be2d RTT average
+ 3fe7b66 pplib dependencies, RTT average

+.SH DESCRIPTION
+DNSMeter is a tool for testing performance of nameserver and/or
+infrastructure around it.
+It generates dns queries and sends them via UDP to a target nameserver
+and counts the answers.
+
+Features:
+.br
+- payload can be given as text file or PCAP file
+.br
+- can automatically run different load steps, which can be given as
+list or ranges
+.br
+- results per load step can be stored in CSV file
+.br
+- sender address can be spoofed from a given network or from PCAP file,
+if payload is a PCAP file
+.br
+- answers are counted, even if source address is spoofed, if answers get
+routed back to the load generator
+.br
+- roundtrip-times are measured (average, min, mix)
+.br
+- amount of DNSSEC queries can be given as percentage of total traffic
+.br
+- optimized for high amount of packets. On an Intel(R) Xeon(R) CPU E5-2430
+v2 @ 2.50GHz it can generate more than 900.000 packets per second
+.SH OPTIONS
+.TP
+.B -h
+Show option help.
+.TP
+.BI -q \ HOST
+Hostname or IP address of sender if you don't want to spoof (see
+.IR -s ).
+.TP
+.BI -s \ NET|pcap
+Spoof sender address.
+Use random IP from the given network (example:
+.IR 192.168.0.0/16 ).
+Only works when running as root!
+If payload is a PCAP file, you can use
+.BI -s pcap
+to use the source addresses and ports from the PCAP file.
+.TP
+.BI -e \ ETH
+Interface on which the packet receiver should listen (FreeBSD only).
+.TP
+.BI -z \ HOST:PORT
+Hostname or IP address and port of the target nameserver.
+.TP
+.BI -p \ FILE
+File with queries/payload or PCAP file.
+.TP
+.BI -l \ #
+Runtime in seconds (default=10 seconds).
+.TP
+.BI -t \ #
+Timeout in seconds (default=2 seconds).
+.TP
+.BI -n \ #
+Number of worker threads (default=1).
+.TP
+.BI -r \ #
+Query rate (Default=as much as possible) can be a single value, a comma
+separated list (rate,rate,...) or a range and a step value (start - end,
+step).
+.TP
+.BI -d \ #
+Amount of queries in percent on which the DNSSEC-flags are set (default=0).
+.TP
+.BI -c \ FILE
+CSV-file for results.
+.TP
+.B --ignore
+Answers are ignored and therefor not counted.
+In this mode the tool only generates traffic.
+.SH USAGE
+This section contains additional usage information not covered by
+the options documentation.
+
+.BI -q \ HOST
+|
+.BI -s \ NETWORK
+|
+.BI -s \ pcap
+
+Source IP, hostname or network from which the packets should be send.
+If you dont't want to spoof, use
+.I -q
+with a single IP address or hostname.
+Use
+.I -s
+followed by a network, if you want to spoof the source address.
+.B dnsmeter
+will generated random IP addresses inside this network.
+Example:
+.B -s
+.IR 10.0.0.0/8 .
+
+If payload is a PCAP file, you can use the source addresses and ports
+from the PCAP file, if you use
+.B -s
+.IR pcap .
+
+.BI -e \ ETH
+
+Ignored on Linux, but on FreeBSD you have to enter the name of the
+network interface on which the tool should listen for the answers.
+
+.BI -p \ FILE
+
+File with payload in text format or PCAP file.
+When using a text format each line must contain one query with name
+and record type.
+
+Example:
+
+ www.denic.de A
+ denic.de NS
+ ...
+
+.IR NOTE :
+the file should not be too big, because it is completely
+loaded into memory and pre-compiled to DNS query packets.
+
+.BI -n \ #
+
+Number of worker threads, recommendation:
+.br
+- less than 200000 packets per second: 1 Thread
+.br
+- 200000 - 500000 packets per second: 2 Threads
+.br
+- more than 500000 packets per second: 4 Threads
+
+.BI NOTE :
+this is CPU dependent!
+If you have a fast CPU, you may need lesser threads, on a slow CPU you
+may need more threads.
+Don't use more threads than cores available on your CPU, minus one!
+
+.BI -r \ #[,#,#]
+
+Query rate or load steps.
+Can be a single value if you want to test a specific query rate, a comma
+separated list or a range with step with.
+
+Examples:
+.br
+- Single value: -r 100000
+.br
+- a list of query rates: -r 10000,20000,30000,40000,50000,60000
+.br
+- a range with step: -r 10000-200000,10000
+
+.BI -d \ #
+
+Amount of DNSSEC queries in percentage between 0 and 100.
+Is ignored, if using PCAP file as payload.
+
+.BI -c \ FILENAME
+
+Filename for results in CSV format.
+
+.BI NOTE :
+if file exists, results are appended!
+
+.SH EXAMPLE
+
+Lets assume the following scenario:
+.br
+- load generator runs on FreeBSD
+.br
+- network interface an which the traffic goes out and comes back is "igb0"
+.br
+- source ip on the load generator is 192.168.155.20
+.br
+- target nameserver has ip 192.168.0.1, port 53
+.br
+- we want to spoof the sender address from the network 10.0.0.0/8
+.br
+- the payload file is found here: /home/testdata/payload.txt
+.br
+- the nameserver is running on CentOS and we need to set a route back to the load generator:
+.br
+ ip route add 10.0.0.0/8 via 192.168.155.20
+.br
+- we want to test the following load steps: 30000,40000,45000,50000,100000,150000
+.br
+- results should be written to results.csv
+.br
+- DNSSEC rate should be 70%
+
+This makes the following command:
+
+ dnsmeter -p /home/testdata/payload.txt \\
+ -r 30000,40000,45000,50000,100000,150000 \\
+ -s 10.0.0.0/8 \\
+ -z 192.168.0.1:53 \\
+ -e igb0 \\
+ -d 70 \\
+ -c results.csv
+
+In the second example, we want to use a PCAP file as payload and want
+to spoof with the addresses from that file:
+
+ dnsmeter -p /home/testdata/pcap.file1 \\
+ -r 30000,40000,45000,50000,100000,150000 \\
+ -s pcap \\
+ -z 192.168.0.1:53 \\
+ -e igb0 \\
+ -c results_pcap.csv
