+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 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 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.
+
+    <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 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 <http://www.gnu.org/licenses/>.
+
+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:
+
+    <program>  Copyright (C) <year>  <name of author>
+    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
+<http://www.gnu.org/licenses/>.
+
+  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

+# The difficulty of the problem
+
+This decompiler is a constant work in progress: Python keeps
+changing, and so does its code generation.
+
+There is no Python decompiler yet that I know about that will
+decompile everything. Overall, I think this one probably does the best
+job of *any* Python decompiler that handles such a wide range of
+versions.
+
+But at any given time, there are a number of valid Python bytecode
+files that I know of that will cause problems. See, for example, the
+list in
+[`test/stdlib/runtests.sh`](https://github.com/rocky/python-uncompyle6/blob/master/test/stdlib/runtests.sh).
+
+But I understand: you would the bugs _you_ encounter addressed before
+all the other known bugs.
+
+From my standpoint, the good thing about the bugs listed in
+`runtests.sh` is that each test case is small and isolated to a single
+kind of problem. And I'll tend to fix easier, more isolated cases than
+generic "something's wrong" kinds of bugs where I'd have to do a bit
+of work to figure out what's up, if not use some sort of mind reading,
+make some guesses, and perform some experiments to see if the guesses
+are correct. I can't read minds, nor am I into guessing games; I'd
+rather devote the effort spent instead towards fixing bugs that are
+precisely defined.
+
+And it often turns out that by just fixing the well-defined and
+prescribed cases, the ill-defined amorphous cases as well will get
+handled as well.
+
+In sum, you may need to do some work to have the bug you have found
+handled before the hundreds of other bugs, and other things I could be
+doing.
+
+No one is getting paid to work to work on this project, let alone the
+bugs you may have an interest in. If you require decompiling bytecode
+immediately, consider using a decompilation service, listed further
+down in this document.
+
+# Is it really a bug?
+
+
+## Do you have valid bytecode?
+
+As mentioned in README.rst, this project doesn't handle obfuscated
+code. See README.rst for suggestions for how to remove some kinds of
+obfuscation.
+
+Checking if bytecode is valid is pretty simple: disassemble the code.
+Python comes with a disassembly module called `dis`. A prerequisite
+module for this package, `xdis` has a cross-python version
+disassembler called `pydisasm`.
+
+## Semantic equivalence vs. exact source code
+
+Consider how Python compiles something like "(x*y) + 5". Early on
+Python creates an "abstract syntax tree" (AST) for this. And this is
+"abstract" in the sense that unimportant, redundant or unnecessary
+items have been removed. Here, this means that any notion that you
+wrote "x+y" in parenthesis is lost, since in this context they are
+unneeded. Also lost is the fact that the multiplication didn't have
+spaces around it while the addition did. It should not come as a
+surprise then that the bytecode which is derived from the AST also has
+no notion of such possible variation. Generally this kind of thing
+isn't noticed since the Python community has laid out a very rigid set
+of formatting guidelines; and it has largely beaten the community into
+compliance.
+
+Almost all versions of Python can perform some sort of code
+improvement that can't be undone. In earlier versions of Python it is
+rare; in later Python versions, it is more common.
+
+If the code emitted is semantically equivalent, then this isn't a bug.
+
+
+For example the code might be
+
+```python
+if a:
+  if b:
+     x = 1
+```
+
+and we might produce:
+
+```python
+if a and b:
+  x = 1
+```
+
+These are equivalent. Sometimes
+
+```
+else:
+   if ...
+
+```
+
+may come out as `elif` or vice versa.
+
+
+As mentioned in the README, It is possible that Python changes what
+you write to be more efficient. For example, for:
+
+
+```python
+if True:
+  x = 5
+```
+
+Python will generate code like:
+
+```python
+x = 5
+```
+
+Even more extreme, if your code is:
+
+```python
+if False:
+   x = 1
+   y = 2
+   # ...
+```
+
+Python will eliminate the entire "if" statement.
+
+So just because the text isn't the same, does not
+necessarily mean there's a bug.
+
+# What to send (minimum requirements)
+
+The basic requirement is pretty simple:
+
+* Python bytecode
+* Python source text
+
+Please don't put files on download services that one has to register
+for or can't get to by issuing a simple `curl` or `wget`. If you can't
+attach it to the issue, or create a github gist, then the code you are
+sending is too large.
+
+Also try to narrow the bug. See below.
+
+# What to send (additional helpful information)
+
+Some kind folks also give the invocation they used and the output
+which usually includes an error message produced. This is
+helpful. From this, I can figure out what OS you are running this on
+and what version of *uncomplye6* was used. Therefore, if you _don't_
+provide the input command and the output from that, please give:
+
+* _uncompyle6_ version used
+* OS that you used this on
+* Python interpreter version used
+
+
+## But I don't *have* the source code!
+
+Sure, I get it. No problem. There is Python assembly code on parse
+errors, so simply by hand decompile that. To get a full disassembly,
+use `pydisasm` from the [xdis](https://pypi.python.org/pypi/xdis)
+package. Opcodes are described in the documentation for
+the [dis](https://docs.python.org/3.6/library/dis.html) module.
+
+### But I don't *have* the source code and am incapable of figuring how to do a hand disassembly!
+
+Well, you could learn. No one is born into this world knowing how to
+disassemble Python bytecode. And as Richard Feynman once said, "What
+one fool can learn, so can another."
+
+If this is too difficult, or too time consuming, or not of interest to
+you, then perhaps what require is a decompilation service. [Crazy
+Compilers](http://www.crazy-compilers.com/decompyle/) offers a
+byte-code decompiler service for versions of Python up to 2.6. (If
+there are others around let me know and I'll list them here.)
+
+# Narrowing the problem
+
+I don't need or want the entire source code base for the file(s) or
+module(s) can't be decompiled. I just need those file(s) or module(s).
+If there are problems in several files, file a bug report for each
+file.
+
+Python modules can get quite large, and usually decompilation problems
+occur in a single function or maybe the main-line code but not any of
+the functions or classes. So please chop down the source code by
+removing those parts that do to decompile properly.
+
+By doing this, you'll probably have a better sense of what exactly is
+the problem. Perhaps you can find the boundary of what decompiles, and
+what doesn't. That is useful. Or maybe the same file will decompile
+properly on a neighboring version of Python. That is helpful too.
+
+In sum, the more you can isolate or narrow the problem, the more
+likely the problem will be fixed and fixed sooner.
+
+# Karma
+
+I realize that following the instructions given herein puts a bit of
+burden on the bug reporter. In my opinion, this is justified as
+attempts to balance somewhat the burden and effort needed to fix the
+bug and the attempts to balance number of would-be bug reporters with
+the number of bug fixers. Better bug reporters are more likely to move
+in the category of bug fixers.
+
+The barrier to reporting a big is pretty small: all you really need is
+a github account, and the ability to type something after clicking
+some buttons. So the reality is that many people just don't bother to
+read these instructions, let alone follow it to any simulacrum.
+
+And the reality is also that bugs sometimes get fixed even though
+these instructions are not followed.
+
+So one factors I may take into consideration is the bug reporter's karma.
+
+* Have you demonstrably contributed to open source? I may look at your
+  github profile to see what contributions you have made, how popular
+  those contributions are, or how popular you are.
+* How appreciative are you? Have you starred this project that you are
+  seeking help from? Have you starred _any_ github project? And the above
+  two kind of feed into ...
+* Attitude. Some people feel that they are doing me and the world a
+  great favor by just pointing out that there is a problem whose solution
+  would greatly benefit them. Perhaps this is why they feel that
+  instructions are not to be followed by them, nor any need for
+  showing evidence gratitude when help is offered them.
+
+# Confidentiality of Bug Reports
+
+When you report a bug, you are giving up confidentiality to the source
+code and the byte code. However, I would imagine that if you have
+narrowed the problem sufficiently, confidentiality of the little that
+remains would not be an issue.
+
+However feel free to remove any comments, and modify variable names
+or constants in the source code.
+
+# Ethics
+
+I do not condone using this program for unethical or illegal purposes.
+More detestable, at least to me, is asking for help to assist you in
+something that might not legitimate.
+
+Don't use the issue tracker for such solicitations. To try to stave
+off illegitimate behavior, you should note that the issue tracker, the
+code, and bugs mentioned in that are in the open: there is no
+confidentiality. You may be asked about the authorship or claimed
+ownership of the bytecode. If I think something is not quite right, I
+may label the issue questionable which may make the it easier those
+who are looking for illegal activity.

 uncompyle6
 ==========
 
-A native Python cross-version Decompiler and Fragment Decompiler.
-Follows in the tradition of decompyle, uncompyle, and uncompyle2.
+A native Python cross-version decompiler and fragment decompiler.
+The successor to decompyle, uncompyle, and uncompyle2.
 
 
 Introduction
 ------------
 
 *uncompyle6* translates Python bytecode back into equivalent Python
-source code. It accepts bytecodes from Python version 2.1 to 3.6 or
-so, including PyPy bytecode and Dropbox's Python 2.5 bytecode.
+source code. It accepts bytecodes from Python version 1.0 to version
+3.8, spanning over 24 years of Python releases. We include Dropbox's
+Python 2.5 bytecode and some PyPy bytecodes.
 
 Why this?
 ---------
 
-There were a number of decompyle, uncompile, uncompyle2, uncompyle3
-forks around. All of them came basically from the same code base, and
-almost all of them no were no longer actively maintained. Only one
-handled Python 3, and even there, only 3.2 or 3.3 depending on which
-code is used. This code pulls these together and moves forward. It
-also addresses a number of open issues in the previous forks.
+Ok, I'll say it: this software is amazing. It is more than your
+normal hacky decompiler. Using compiler_ technology, the program
+creates a parse tree of the program from the instructions; nodes at
+the upper levels that look a little like what might come from a Python
+AST. So we can really classify and understand what's going on in
+sections of Python bytecode.
 
-What makes this different from other CPython bytecode decompilers?: its
-ability to deparse just fragments and give source-code information
-around a given bytecode offset.
+Building on this, another thing that makes this different from other
+CPython bytecode decompilers is the ability to deparse just
+*fragments* of source code and give source-code information around a
+given bytecode offset.
 
-I use this to deparse fragments of code inside my trepan_
-debuggers_. For that, I need to record text fragments for all
-bytecode offsets (of interest). This purpose although largely
-compatible with the original intention is yet a little bit different.
-See this_ for more information.
+I use the tree fragments to deparse fragments of code *at run time*
+inside my trepan_ debuggers_. For that, bytecode offsets are recorded
+and associated with fragments of the source code. This purpose,
+although compatible with the original intention, is yet a little bit
+different.  See this_ for more information.
 
-The idea of Python fragment deparsing given an instruction offset can
-be used in showing stack traces or any program that wants to show a
-location in more detail than just a line number.  It can be also used
-when source-code information does not exist and there is just bytecode
-information.
+Python fragment deparsing given an instruction offset is useful in
+showing stack traces and can be encorporated into any program that
+wants to show a location in more detail than just a line number at
+runtime.  This code can be also used when source-code information does
+not exist and there is just bytecode. Again, my debuggers make use of
+this.
+
+There were (and still are) a number of decompyle, uncompyle,
+uncompyle2, uncompyle3 forks around. Many of them come basically from
+the same code base, and (almost?) all of them are no longer actively
+maintained. One was really good at decompiling Python 1.5-2.3, another
+really good at Python 2.7, but that only. Another handles Python 3.2
+only; another patched that and handled only 3.3.  You get the
+idea. This code pulls all of these forks together and *moves
+forward*. There is some serious refactoring and cleanup in this code
+base over those old forks. Even more experimental refactoring is going
+on in decompyle3_.
+
+This demonstrably does the best in decompiling Python across all
+Python versions. And even when there is another project that only
+provides decompilation for subset of Python versions, we generally do
+demonstrably better for those as well.
+
+How can we tell? By taking Python bytecode that comes distributed with
+that version of Python and decompiling these.  Among those that
+successfully decompile, we can then make sure the resulting programs
+are syntactically correct by running the Python interpreter for that
+bytecode version.  Finally, in cases where the program has a test for
+itself, we can run the check on the decompiled code.

+We are serious about testing, and use automated processes to find
+bugs. In the issue trackers for other decompilers, you will find a

+In older versions of Python it was possible to verify bytecode by

+could be compared with the original bytecode. However as Python's code
+generation got better, this no longer was feasible.

+the syntax.

 Known Bugs/Restrictions
 -----------------------
 
 The biggest known and possibly fixable (but hard) problem has to do
-with handling control flow. All of the Python decompilers I have looked
-at have the same problem. In some cases we can detect an erroneous
-decompilation and report that.
+with handling control flow. (Python has probably the most diverse and
+screwy set of compound statements I've ever seen; there
+are "else" clauses on loops and try blocks that I suspect many
+programmers don't know about.)
 
-About 90% of the decompilation of Python standard library packages in
-Python 2.7.12 verifies correctly. Over 99% of Python 2.7 and 3.3-3.5
-"weakly" verify. Python 2.6 drops down to 96% weakly verifying.
-Other versions drop off in quality too.
+All of the Python decompilers that I have looked at have problems
+decompiling Python's control flow. In some cases we can detect an
+erroneous decompilation and report that.
 
-*Verification* is the process of decompiling bytecode, compiling with
-a Python for that bytecode version, and then comparing the bytecode
-produced by the decompiled/compiled program. Some allowance is made
-for inessential differences. But other semantically equivalent
-differences are not caught. For example ``1 and 0`` is decompiled to
-the equivalent ``0``; remnants of the first true evaluation (1) is
-lost when Python compiles this. When Python next compiles ``0`` the
-resulting code is simpler.
+Python support is strongest in Python 2 for 2.7 and drops off as you
+get further away from that. Support is also probably pretty good for
+python 2.3-2.4 since a lot of the goodness of early the version of the
+decompiler from that era has been preserved (and Python compilation in
+that era was minimal)
 
-*Weak Verification*
-on the other hand doesn't check bytecode for equivalence but does
-check to see if the resulting decompiled source is a valid Python
-program by running the Python interpreter. Because the Python language
-has changed so much, for best results you should use the same Python
-Version in checking as used in the bytecode.
-
-Later distributions average about 200 files. There is some work to do
-on the lower end Python versions which is more difficult for us to
-handle since we don't have a Python interpreter for versions 1.5, 1.6,
-and 2.0.
+There is some work to do on the lower end Python versions which is

+interpreter for versions 1.6, and 2.0.
 
 In the Python 3 series, Python support is is strongest around 3.4 or
 3.3 and drops off as you move further away from those versions. Python
-3.5 largely works, but still has some bugs in it and is missing some
-opcodes.  Python 3.6 changes things drastically by using word codes
-rather than byte codes. That has been addressed, but then it also
-changes function call opcodes and its semantics and has more problems
-with control flow than 3.5 has.
+3.0 is weird in that it in some ways resembles 2.6 more than it does
+3.1 or 2.7. Python 3.6 changes things drastically by using word codes
+rather than byte codes. As a result, the jump offset field in a jump
+instruction argument has been reduced. This makes the :code:`EXTENDED_ARG`
+instructions are now more prevalent in jump instruction; previously
+they had been rare.  Perhaps to compensate for the additional
+:code:`EXTENDED_ARG` instructions, additional jump optimization has been
+added. So in sum handling control flow by ad hoc means as is currently
+done is worse.
+
+Between Python 3.5, 3.6, 3.7 there have been major changes to the
+:code:`MAKE_FUNCTION` and :code:`CALL_FUNCTION` instructions.  Python
+
+Python 3.8 removes :code:`SETUP_LOOP`, :code:`SETUP_EXCEPT`,
+:code:`BREAK_LOOP`, and :code:`CONTINUE_LOOP`, instructions which may
+make control-flow detection harder, lacking the more sophisticated
+control-flow analysis that is planned. We'll see.
 
 Currently not all Python magic numbers are supported. Specifically in
 some versions of Python, notably Python 3.6, the magic number has
-changes several times within a version. We support only the released
-magic. There are also customized Python interpreters, notably Dropbox,
+changes several times within a version.
+
+**We support only released versions, not candidate versions.** Note
+however that the magic of a released version is usually the same as
+the *last* candidate version prior to release.
+
+There are also customized Python interpreters, notably Dropbox,
 which use their own magic and encrypt bytcode. With the exception of
 the Dropbox's old Python 2.5 interpreter this kind of thing is not
 handled.
