+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://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.

+
+  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>

+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or

+
+    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 <https://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
+<https://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

 Task Time Tracker
 =================
 
+A tool to keep track of the time spent on tasks.
+
+# Why use it?
+
+Why not? Besides, you'll be able to create, duplicate, move, rename,
+archive, restore and delete tasks at the distance of one (or two) key
+stroke(s). You'll also be able to edit the time spent on a task by
+adding, subtracting or setting the time you want. But that's not all!
+
+With the Track'n'Close technology, you won't need to keep the app always
+open. Once you start tracking time for a task, the app will keep track
+of it, even if you close it or turn off your computer.
+
+Count seconds, minutes, hours, days, and even years... all the way up to
+infinity\* thanks to the not-so-new technology of 64 bit integers.
+
+Be amazed by the compact interface that automatically adapts the time
+representations while maximizing the displayed precision.
+
+Cleanup the workspace by moving your finished tasks to the archive. Want
+to bring back some archived tasks? No problem, just switch into the
+archive view and restore them.
+
+Ever felt like your data is being held hostage? Not anymore! Import and
+export your tasks using the widely supported CSV text file format.
+
+Want to be part of the last frontier? Grab the bleeding edge version 2
+which brings: sorting capabilities; better text input with UTF8
+support; possibility to archive and reset all current tasks with a
+single command; and allows to merge tasks with the same name. As an
+extra , you'll need to export and re-import your tasks due to some
+database incompatibility (oh, the joy).
+
+And if you don't like what you're seeing, this is your lucky day!
+Because you have access to the source code, you can adapt it to your
+needs!
+
+**Task Time Tracker - *You may not need it, but I enjoyed making it!***
+
+*\* Although the app cannot count to infinity, it surely displays it (∞)
+if the time goes to 9999.5 years or above. Also, it will display a minus
+(-) if you force a time to have negative values.*
+
+# Why create such tool?
+
+I like to keep track of the time spent on my daily job's tasks. It helps
+me be aware of time pits, and improve my time estimates. This motivated
+me to search for a simple app that allowed to take measurements without
+too much effort.
+
+After skimming through all cloud-based and too-complex apps, I
+eventually landed on some text-based user interface (TUI) apps. The one
+that almost convinced me was [worklog](https://github.com/atsb/worklog),
+but I just couldn't come to terms with its interface.
+
+So, after spending more time than I'd like to admit searching for a task
+time tracker, I decided to take matters on my own hands. Maybe I just
+needed to improve my search-fu. Maybe it was just an excuse to write
+some code. Either way, I wasn't turning back.
+
+# Why use C and ncurses?
+
+I've been looking for an excuse to revisit C, which I haven't used for
+more than a decade, and this seemed like a good opportunity: a simple
+app with a small set of features. But how would I build the user
+interface? I didn't want to learn an advanced toolkit just for this
+small project, and since the TUI apps had somehow resonated with me, I
+decided to try out the ncurses library which has been surviving the test
+of time.
+
+Because this was an hobby project focused in exploring C and its
+standard library, I allowed myself to obsess with whatever details I
+wanted to. This serves to justify the lousy code, and explains the fun I
+had.
+
+Overall, it was a satisfying experience with occasional moments of
+frustration whenever "string" manipulations were required. And now that
+the first part is completed the best part begins: let's try to implement
+it in Jai and get some hands-on experience of how the two compare. See
+you on the other side. 🖖
+
+# What is Jai?
+
+Jai is a temporary name used for the programming language being
+developed at Thekla, Inc.
+
+# Why port it to Jai?
+
+Because I love to explore, and I needed an excuse to try out the Jai
+compiler I got access in the meantime. This allowed me to experiment and
+compare this new programing language against the original C
+implementation.
+
+During the initial pass to port the code, I made some small adaptations
+due to syntax differences, and improved some data types (finally, I
+could replace all those `*u8` with proper `string`). The initial pass
+was easy, so I decided to add some features I missed while using the app
+on my daily job.
+
+Still, the ncurses dependency was bothering me. Although the language is
+well prepared to interact with C/C++ libraries, and I was able to
+quickly setup the necessary bindings to use ncurses, it didn’t fell
+right… this dependency was blocking me from building this app for
+different operating systems (OS). Could I replace ncurses with something
+native to this language? Yes… but that require much reading and coding,
+and that’s what I did.
+
+After surfing an uncountable number of websites and manuals about linux,
+terminals, escape codes, and whatnot, I ended up creating
+[TUI](https://github.com/gudinoff/jai-modules), a simple terminal user
+interface module that provides basic functionalities similar to the
+[ncurses library](https://en.wikipedia.org/wiki/Ncurses), written in Jai
+to allow portability between OSs.
+
+Working with this new language was a joyful experience. Most of the time
+it felt like I was simply cleaning up (simplifying) the code, with very
+little friction. There was no hiccups setting up the project or adding
+new modules, it all just worked. I really hope this language gets to
+spread its wings.

-# To-do list
-- [x] Include check on number of char bits;
-- [x] Decide once for all if I'll be using uint8_t or char for strings: use char.
-- [x] maybe rename to task-time-tracker?
-- [x] Remove hash stuff;
-- [x] Tasks should have a `modified_on` timestamp field;
-- [x] Change capacity to size_t. 
-- [x] Change active_task to active_task_ptrdiff. 
-- [x] Use selected_task_ptrdiff?
-- [x] Make sure task names don't include commas ',';
-- [x] Format time being displayed.
-- [x] Replace max_capacity by its true value;
-- [x] Replace intmax_t by int64_t;
-- [x] Adapt input cycle to work with `database_t *db` to allow pointing to database/archive.
-- [x] Show a symbol to let the user know when we're seeing the archive.
-- [x] Status of task will allow to keep counting time even when the process gets terminated forcefully;
-- [x] Review code: char !uint8_t;
-- [x] Make sure that only one task is running at each time;
-- [x] Mouse selection is broken due to entire TUI update: No, it was fixed by using `erase()` on the `draw_tui` instead of `clear()`;
-- [x] I bet the headers are no longer being used all on a single cycle. Let's separate them and include "header_title_archive";
-- [x] Rename layout members: title_header, archive_header, total_header, days_headers, column_widths, column_alignments, headers_paddings.
-- [x] Using the archive header, we can remove the top-left-corner diamond on the archive.
-- [x] Allow to cancel a rename_task operation: you can do it by leaving it blank.
-- [x] Make sure we are not using `strcat` and `strcpy`... or that we are using them wisely (famous last words).
-- [x] Make archive be stored in CSV format: takes less space and allows to quickly archive by appending to end of file;
-- [x] Implement `append_to_csv(task_t *task, char *path_name)` and use it in archive function;
-- [x] At startup, check for required files and create them if not present.
-- [x] Allow to archive task using keys: `a` and `A`;
-- [x] By default, store files on `~/.config/task_time_tracker/` or `~/.local/share/task_time_tracker` and allow to store elsewhere if passed by argument `--config`.
-- [x] Allow usage of `ttt: ./ttt --dpath ./` to change the app folder: To changes app data path change the environment variable HOME (USERPROFILE for windows users).
-- [x] Clone (replicate) task; If task is active, mark newly created task as inactive;
-- [x] Check if next/previous is safe against overflows/underflows using https://gcc.gnu.org/onlinedocs/gcc/Integer-Overflow-Builtins.html
-- [x] Confirm delete_task operation by show confirmation message on selected line (horizontally centered).
-- [x] Check totals update speedup using https://gcc.gnu.org/onlinedocs/gcc/Integer-Overflow-Builtins.html
-	- For 1M entries, generic C code runs in 12.0ms while special approaches using builtins or SIMD takes around 9.5ms.
-	- Used optimization described [here](https://stackoverflow.com/questions/17580118/signed-saturated-add-of-64-bit-ints).
-- [x] Allow to jump to specific task by index number using key `g` and `G`;
-- [x] Move task to (using task_t tmp_task + memcpy) using key `m` and `M`;
-- [x] Rethink keys;
-	- [x] Create task using keys: `n` and `N`;
-	- [x] Delete task using key: delete;
-	- [x] Change task name using keys: `F2`;
-	- [x] Duplicate task using keys: `d` and `D`;
-- [x] Add/remove time using keys: `F3`;
-- [x] Add/remove time for any day of week;
-- [x] Total times may saturate, but before that the user will see the infinite symbol. Solution: Provide user with possibility to refresh totals.
-- [x] Decide on a INVALID_WINDOW_MESSAGE.
-- [x] Use backspace to clear all timers for current task.
-- [x] Move `store_database_partial` to misc and save only when leaving or after 15 seconds of inactivity and having dirty flag set.
-- [x] Register kill signals to exit gracefully.
-- [x] Check if string_buffer needs to be cleared. We may be leaking info on the string_buffer.
-- [x] Replaced `sprintf` by `snprintf`;
-- [x] Make sure that string_buffer bounds are respected;
-- [x] Rename `MAX_TASK_NAME` to something more informative;
-- [x] Compress code:
-	- [x] Re-do sprint_time5_utf8: -12 delta LOC;
-	- [x] Re-do truncate_string_utf8: 0 delta LOC;
-	- [x] Implement `read_input_to_string_buffer`: -24 delta LOC;
-	- [x] Wrap malloc (and maybe others) in a function with error checking;
-	- [x] Move database actions into functions;
-- [x] Fix bug: archiving/unarchiving task introduces " ," at end of name and increases the number of spaces before comma;
-- [x] Check if draw_tui may be simplified by drawing entire lines of tasks at once and draw columns separators after;
-	- By having each column-print job decoulpled, we avoid havint to measure and compensate lengths of UTF8 strings;
-- [x] Review all code for bugs related to auto-cast on ptrdiff_t (signed/unsigned);
-- [x] Review all code for bugs related to auto-cast on size_t (signed/unsigned);
-- [x] Go over all to-do items;
-- [x] Hide stderr messages from app screen.
-- [x] Improve error detection/messages.

+===========

+Modules for the language being developed by Thekla, Inc.
+
+# Saturation
+
+This module provides basic integer [saturation arithmetic](https://en.wikipedia.org/wiki/Saturation_arithmetic) procedures: `add`, `sub`, `mul`, and `div`.  
+These procedures accept any of the built-in integer types and adjust the output accordingly, e.g., adding an `u8` with an `s16` results in an `s16`;  
+All procedures return a flag signaling if the result is saturated and, additionally, the division procedure returns the remainder;  
+Branch-free procedures are included for the x64 architecture. These may be used by setting the `PREFER_BRANCH_FREE_CODE` module argument, or by setting `prefer_branch_free_code` on each function call. These should speed things up, specially when using signed values. Some benchmarks are included on the tests file.  
+
+# TUI
+
+A simple terminal user interface module that provides basic functionalities similar to the [ncurses library](https://en.wikipedia.org/wiki/Ncurses).  
+Usefull for creating simple terminal-based apps that require user input.  
+View `snake.jai` for an example.  
+It has been tested on the following terminal emulators:
+- [GNOME Terminal](https://en.wikipedia.org/wiki/GNOME_Terminal)
+- [kitty](https://en.wikipedia.org/wiki/Kitty_(terminal_emulator))
+- [Konsole](https://en.wikipedia.org/wiki/Konsole)
