+ GNU GENERAL PUBLIC LICENSE
+
+ Version 3, 29 June 2007
+
+ Copyright © 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.
+

+### Goal
+
+There are a lot of bird-perspective greyscale FLIR-images made by a drone, which don't get stitched well together automatically.
+But we have geo-coordinates as metadata.
+
+It will be manual work, but maybe we can semi-automatize it.
+
+### How it works
+
+The process has three steps:
+1. Putting the tiles onto an SVG-canvas using a python script.
+ You may want to try around with the settings (scaling, rotation, etc) of the CLI tool until you get a useful SVG.
+2. Manual Editing of the SVG.
+ There are errors in the GPS data and FLIR data.
+ Correct them manually using Inkscape or similar Vector Graphics software.
+3. Converting the SVG canvas into a GeoTIFF
+ The script produces 16-bit greyscale PNG-Files, representing the temperature, and exports the SVG into a big PNG image.
+ This PNG image gets then projected and converted into a GeoTIFF, using temperature information from the grey-scale value of the PNG
+
+The two python scripts:
+
+* `gis-svg-stitcher.py` for putting the tiles onto an SVG canvas
+ Example usage:
+ ```
+ python3 gis-svg-stitcher.py relative_path_to_the_imagefiles --scale=15 --base_rotation=115 --rotation_corr_left=28
+ ```
+ It produces a file called `map.svg`
+
+* `convert-svg-to-geotiff.py` for converting the (edited) SVG canvas
+ Example usage:
+ ```
+ python3 convert-svg-to-geotiff.py relative_path_to_the_imagefiles/map.svg output.tiff
+ ```
+
+
+### Requirements
+
+* python3 + pip
+* inkscape
+* firefox
+
+### Installation
+
+Install Python3, Inkscape and Firefox.
+
+Then clone repo and install script dependencies:
+```
+git clone https://git.notice.at/redplanet/deep-crop.git
+cd deep-crop
+pip3 install -r requirements.txt
+```
+
+### How to use
+
+Use the scripts. Use the `--help` flag for more information:
+
+```
+python3 gis-svg-stitcher.py --help
+```
+and
+```
+python3 convert-svg-to-geotiff.py --help
+```
