-                    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
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# Building pdf2htmlEX
+
+Because of its intimate use of *specific* versions of both Poppler and 
+FontForge, cleanly building `pdf2htmlEX` is rather more complex than 
+normal. 
+
+The (shell) scripts in this directory help automate this mutli-stage 
+process. 
+
+For all but the most experienced programmers, we *strongly* encourage you 
+to use these scripts to build `pdf2htmlEX`.

+

+
+## TL;DR ...
+
+### Downloading precompiled versions
+
+For most users, you probably really want to simply download one of the 
+[precompiled versions of 
+`pdf2htmlEX`](https://github.com/pdf2htmlEX/pdf2htmlEX/releases): 
+
+- [Debian archive](https://en.wikipedia.org/wiki/Dpkg) : Download, 
+  [apt](https://en.wikipedia.org/wiki/APT_(software)) install locally, 
+  and run... 
+
+  This will work on any [Debian](https://www.debian.org/) based and most 
+  recent Windows 10 machines. 
+
+  Experienced users of Linux, may be able to repackage the `*.deb` we 
+  provide for use with their favourite package management tool. 
+
+- [AppImage](https://appimage.org/) : Download, make executable, and 
+  run... 
+
+  This will work on most Linuxes, and most recent Windows 10.
+  
+  (It will not currently work on MacOS or Alpine based machines).
+
+- [OCI](https://opencontainers.org/) Image from the [`pdf2htmlEX` Docker 
+  hub](https://hub.docker.com/orgs/pdf2htmlex/repositories). 
+
+  This will work on any machine with an OCI Container system (such as 
+  Docker, Podman, CRI-O, Kubernetes) installed. 
+
+  (Note: that *advanced* use of `pdf2htmlEX` requires careful attention to 
+  the configuration of various tools, such as fontconfig, iconv and your 
+  locally available fonts use by the poppler and fontforge libraries. The 
+  OCI container images created by the pdf2htmlEX team might not be as well 
+  configured for *your needs* as an OCI container created and configured 
+  by you) 
+
+### Building yourself
+
+To build `pdf2htmlEX` on a Debian/Apt related machine, inside the root 
+directory of a fresh clone of the 
+[pdf2htmlEX/pdf2htmlEX](https://github.com/pdf2htmlEX/pdf2htmlEX) 
+repository, type: 
+
+```
+    ./buildScripts/buildInstallLocallyApt
+```
+
+This will automatically install all required development tools and 
+libraries, and then proceed to download and statically compile the 
+required versions of both Poppler and FontForge before compiling and 
+installing `pdf2htmlEX` into /usr/local/bin. 
+
+**NOTE:** at the moment this will **only** work on machines with a 
+[Debian](https://www.debian.org/) based distribution. such as 
+[Ubuntu](https://ubuntu.com/), [Linux Mint](https://linuxmint.com/), etc. 
+
+**NOTE:** there is currently an *experimental* build script, 
+`./buildScripts/buildInstallLocallyAlpine`, for builds in Alpine 
+environments. 
+
+## The problem
+
+To provide its full functionality, the `pdf2htmlEX` sources make direct 
+use of source code and unexposed methods from both the Poppler and 
+FontForge projects. Unfortunately the source code in the Poppler and 
+FontForge projects that the `pdf2htmlEX` uses changes regularly.
+
+This means that the `pdf2htmlEX` souce code *must* be updated regularly to 
+match *specific releases* of both Poppler and FontForge. 
+
+Unfortunately, the installed versions of both Poppler and FontForge in 
+most Linux distributions, lag the official releases of both of these 
+projects. Even worse few distributions install the same versions.
+
+This means that it is nearly impossible for the `pdf2htmlEX` code to 
+'predict' which version of Poppler or FontForge will be installed on a 
+given user's machine. 
+
+## Our solution
+
+While we *could* keep multiple versions of the `pdf2htmlEX` source code, 
+each version matched to a particular distribution's installed versions of 
+Poppler and FontForge, this would be a logistic and testing 'nightmare'. 
+
+Instead, when building `pdf2htmlEX`, we download specific versions of both 
+the Poppler and FontForge sources (usually the most recent), and then 
+compile *static* versions of the Poppler and FontForge libraries which are 
+then *statically* linked into the `pdf2htmlEX` binary. 
+
+This means that the `pdf2htmlEX` binary is completely independent of any 
+locally installed versions of either Poppler or FontForge.
+
+However, to get the matched versions of Poppler and FontForge and then 
+compile them statically, *our* build process becomes much more complex 
+than a "simple", `configure, make, make install` cycle. 
+
+Hence this directory has a large number of shell scripts each of which 
+automate one simple step in the overall our build process. 
+
+## The gory details ...
+
+The shell scripts in this directory automate the download, build, install, 
+test and upload steps required to provide a complete build/test/release 
+cycle of `pdf2htmlEX`. 
+
+Each script can be used individually to re-run a particular step if needed.
+
+### Top-level scripts
+
+Typically, most users, will run one of the following "top-level" scripts: 
+
+1. **`buildInstallLocallyApt`** (**`buildInstallLocallyAlpine`**)
+
+   This will automate:
+
+     1. the installation of all required development tools 
+        and libraries,
+  
+     2. download and statically compile the required versions of both 
+        Poppler and FontForge, 
+
+     3. compile and install `pdf2htmlEX`.
+
+   The `*Apt` script will build on any machine which uses the 
+   `apt`/`apt-get` command. 
+
+   The `*Alpine` script will build on any machine which uses the 
+   `apk` command (Alpine). 
+
+2. **`createImagesApt`** (**`createImagesAlpine`**)
+
+   Following a successful `buildInstallLocallyApt`, the `createImagesApt` 
+   shell script will create the following images: 
+
+     1. AppImage
+
+     2. OCI Container image
+
+     3. Debian archive
+
+   Following a successful `buildInstallLocallyAlpine`, the 
+   `createImagesAlpine` shell script will create the following images: 
+
+     1. Alpine tar file
+
+     2. OCI Container image
+
+3. **`runTests`**
+
+   Following a successful `buildInstallLocallyApt` (or 
+   `buildInstallLocallyAlpine` ), the `runTests` shell script will run the 
+   various 'local' tests reporting errors as they occur. 
+
+   When run in [Travis-ci](https://travis-ci.org/), failing browser tests 
+   will *not* fail the overall Travis build, but will instead upload the 
+   test results to the GitHub Release page for later review. 
+
+4. **`uploadImages`**
+
+   Following successful `buildInstallLocally`, `createImages` and 
+   `runTests`, this will automate the upload of the various artefacts to 
+   the `pdf2htmlEX` releases page, and docker hub repository. 
+
+   **Note** that this step requires the user to enter passwords for each 
+   of the respective services. *Most* users will not need (or be able) to 
+   run this step. 
+
+5. **`travisLinuxDoItAll`**
+
+   This script is used by the `.travis.yml` configuration to build, test 
+   and upload a complete `pdf2htmlEX` release cycle. It is essentially a 
+   compendium of all of the build scripts in the correct order. 
+
+### Individual steps
+
+- **`buildFontforge`**: Compiles a *static* version of `libfontforge` for 
+  use by `pdf2htmlEX`.
+
+  Statically linking `libfontforge` into `phd2htmlEX` ensures that any 
+  versions of FontForge already installed by the user, are not broken by 
+  the user's installation of `pdf2htmlEX`. 
+
+- **`buildPdf2htmlEX`**: Compiles and links `pdf2htmlEX`. 
+
+- **`buildPoppler`**: Compiles a *static* version of `libpoppler` and 
+  `libpopper-glib` for use by `pdf2htmlEX`. 
+
+  Statically linking `libpoppler` and `libpoppler-glib` into `phd2htmlEX` 
+  ensures that any versions of Poppler already installed by the user, are 
+  not broken by the user's installation of `pdf2htmlEX`. 
+
+- **`createAlpineTarFile`**: Using an already compiled version of `pdf2htmlEX`, 
+  installs it and `popper-data` into a tar file suitable for use in any 
+  Alpine environment. 
+
+- **`createAppImage`**: Using an already compiled version of `pdf2htmlEX`, 
+  installs it and `popper-data` into an AppImage.
+
+- **`createDebianPackage`**: Using an already compiled version of 
+  `pdf2htmlEX`, installs it and `poppler-data` into a Debian archive 
+  (`*.deb`). 
+
+- **`createContainerAlpineImageFromTarFile`**: Installs the Alpine tar file 
+  archive of `pdf2htmlEX` created by `createAlpineTarFile` into an Alpine 
+  Container. 
+
+- **`createContainerUbuntuImageFromDeb`**: Installs the Debian archive of 
+  `pdf2htmlEX` created by `createDebianPackage` into a Container. 
+
+- **`getBuildToolsAlpine`**: Locally `apk` installs all development 
+  *tools* required to build `pdf2htmlEX`. 
+
+- **`getBuildToolsApt`**: Locally `apt` installs all development *tools* 
+  required to build `pdf2htmlEX`. 
+
+- **`getDevLibrariesAlpine`**: Locally `apk` installs all development 
+  *libraries* required to build `pdf2htmlEX`.
+
+- **`getDevLibrariesApt`**: Locally `apt` installs all development 
+  *libraries* required to build `pdf2htmlEX`.
+
+  This script provides a definitive list of all libraries required to run 
+  `pdf2htmlEX`. 
+
+  This script provides a definitive list of all libraries required to run 
+  `pdf2htmlEX`. 
+
+- **`getFontforge`**: Downloads and unpacks the version of FontForge specified in the 
+  `FONTFORGE_VERSION` environment variable into the 
+  `pdf2htmlEX/fontoforge` directory.
+
+  The `FONTFORGE_VERSION` variable is specified in the `versionEnvs` 
+  script. 
+
+- **`getPoppler`**:  Downloads and unpacks the version of Poppler specified in the 
+  `POPPLER_VERSION` environment variable into the `pdf2htmlEX/poppler` 
+  directory.
+
+  The `POPPLER_VERSION` variable is specified in the `versionEnvs` script. 
+
+  The `getPoppler` script also downloads and unpacks the most recent 
+  version of `poppler-data`. Since `poppler-data` does not change very 
+  often, the correct version of `poppler-data` is specified in the 
+  `getPoppler` script itself. 
+
+- **`installPdf2htmlEX`**: Installs an already compiled version of 
+  `pdf2htmlEX` and `poppler-data` into the location specified by the 
+  `PDF2HTMLEX_PREFIX` environment variable.
+
+  The `PDF2HTMLEX_PREFIX` variable is specified in the `versionEnvs` 
+  script. 
+
+- **`runTests`**: Runs the tests located in the 
+  `pdf2htmlEX/pdf2htmlEX/test` directory. See the 
+  `pdf2htmlEX/pdf2htmlEx/test` directory's Readme file for details. 
+
+- **`uploadContainerImage`**: Upload the `pdf2htmlEX` Container image to 
+  Docker hub repository associated to the docker hub users specified in 
+  the `DOCKER_HUB_USERNAME` environement variable.
+
+  Unless the `DOCKER_HUB_USERNAME` and `DOCKER_HUB_PASSWORD` environment 
+  variables are pre-defined, this script will prompt the user for the 
+  respective values. 
+
+- **`uploadGitHubRelease`**: Upload the `pdf2htmlEX` artefacts (AppImage, 
+  Debian archive, test results, etc) to the *continuous* section of the 
+  release page associated with the `TRAVIS_REPO_SLUG` (user/project) 
+  environment variable.
+
+  Unless the `GITHUB_USERNAME`, `GITHUB_TOKEN`, and `TRAVIS_REPO_SLUG` 
+  (user/project) environment variables are pre-defined, this script will 
+  prompt the user for the respective values. 
+
+### Helper files and scripts
+
+- **`versionEnvs`**: Specifies all of the evnironment variables required 
+  for a standard build of `pdf2htmlEX`. Changes in this script effect 
+  *all* of the other build scripts. 
+
+- **`reSourceVersionEnvs`**: This shell script is automatically generated 
+  by the build scripts as they are run. It records the values of all 
+  important environment variables required by the buildScripts. It is 
+  typcically `source`d by each script before it preforms any actions. 
+
+- **`reportEnvs`**: Echos all important enviroment variables to the 
+  console. This script is used by the top-level scripts to ensure the 
+  current environment variables are listed before each build. 
+
+- **`uploadGitHubReleaseDSL`**: A collection of shell functions used by the 
+  `uploadGitHubRelease` script to automate the upload of release artefacts.
+
+- **`uploadGitHubReleaseMessage`**: The contents of this *text* file is 
+  used by the `uploadGitHubRelease` script as the contents of the release 
+  message, as visible to the user, for the 'continuous' release section. 
+
+- **`listFilesByChangeTime`**: A simple shell script which lists the files 
+  in the buildScripts directory by most recently changed files first. 
+
+- **`Readme.md`**: This read me file.
+
+## Yet more details?
+
+The various shell script files are meant to be fairly readable. They 
+contain additional comments about what each step is meant to be doing.

+# This shell script is a collection of functions to interact with the GitHub
+# release and git/tag APIs. It essentially provides a shell script based DSL
+# for uploading GitHub release artefacts.
+
+# NOTE-1: These functions make use of your ".netrc" file to authenticate
+# with GitHub. In order to use these functions, make sure you have **both**
+# "api.github.com" and "upload.github.com" in this file. For example:
+#
+#    machine api.github.com
+#      login foca
+#      password <an access token>
+#    machine uploads.github.com
+#      login foca
+#      password <an access token>
+#
+# You can generate the required access token at
+#    https://github.com/settings/tokens
+# Make sure this access token has access to the "repo" scope.
+#
+# NOTE-2: These functions require the "jq" library to parse the JSON
+# returned by the GitHub APIs.

+This is the most recent release of the pdf2htmlEX project.
+
+We release three types of binary objects:
+
+1. The file *.AppImage on this release page is an AppImage
+
+   You can download the AppImage, make it executable and then 'just run 
+   it'. 
+
+   See: https://appimage.org/ for details
+
+2. The file *.deb is a Debian Archive
+
+   You can download the Debian Archive and install it locally using: 
+   
+       sudo apt install <<releativePathToDebFile>>
+
+   While the Debian archive is built on a specific Ubuntu release, it can 
+   usually be used on any more recent Ubuntu releases. 
+
+3. You can alternatively get pdf2htmlEX Container images from Docker Hub in 
+   either of the repositories: 
+
+       pdf2htmlEX/pdf2htmlEX (offical release)
+
+   or 
+
+       stephengaito/pdf2htmlEX (development releases)
+
+We also release a zip archive of the browser test results in the 
+*-testResults.zip file. 
+
+Finally, the various *.txt and *buildInfo.sh files have well known 
+(unchanging) names which can be used by automatic scripts to identifiy the 
+current full names of the corresponding binary artifacts.
