+                    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.
+
+  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

+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+    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

+
+  The GNU General Public License does not permit incorporating your program

+```
+
+## Prerequisites
+
+* A guide on how to set up Anki can be found [on our site](https://tatsumoto.neocities.org/blog/setting-up-anki.html).
+* If you're on a [Windows](https://www.fsf.org/windows) or a [Windows-like](https://reactos.org/) machine,
+  a mpv build by `shinchiro` is recommended.
+* **macOS** users are advised to use [homebrew](https://brew.sh/) or manually add `mpv` to `PATH`.
+* Note that it is not recommended to use FlatPak or similar containers.
+  If you still want to, [read this](howto/flatpak.md).
+* Make sure that your build of mpv supports encoding of audio and images.
+  This shell command can be used to test it.
+
+  ```
+  $ mpv 'test_video.mkv' --loop-file=no --frames=1 -o='test_image.jpg'
+  ```
+
+  If the command fails, find a compatible build on the [mpv website](https://mpv.io/installation/)
+  or instead install FFmpeg and [enable FFmpeg support](#configuration) in `mpvacious`'s config file.
+* Most problems with adding audio or images to Anki cards can be fixed
+  by installing FFmpeg and enabling it settings.
+
+## Installation
+
+There are multiple ways you can install `mpvacious`.
+I recommend installing with `git` so that you can easily update on demand.
+
+`mpvacious` is a user-script for mpv,
+so it has to be installed in the directory `mpv` reads its user-scripts from.
+
+| OS        | Location                                         |
+|-----------|--------------------------------------------------|
+| GNU/Linux | `~/.config/mpv/scripts/`                         |
+| Windows   | `C:/Users/Username/AppData/Roaming/mpv/scripts/` |
+
+Windows is not recommended,
+but we acknowledge that some people haven't switched to GNU/Linux yet.
+
+### Using git
+
+Clone the repo to the `scripts` directory.
+
+```
+mkdir -p ~/.config/mpv/scripts/
+git clone 'https://github.com/Ajatt-Tools/mpvacious.git' ~/.config/mpv/scripts/subs2srs
+```
+
+To update, run the following command.
+
+```
+cd ~/.config/mpv/scripts/subs2srs && git pull
+```
+
+### From the AUR
+
+`mpvacious` can be installed with the [mpv-mpvacious](https://aur.archlinux.org/packages/mpv-mpvacious/) package.
+
+### Manually
+
+This way is not recommended because it's easy to make a mistake during the process
+and end up with a broken install.
+
+Download
+[the repository](https://github.com/Ajatt-Tools/mpvacious/archive/refs/heads/master.zip)
+or
+[the latest release](https://github.com/Ajatt-Tools/mpvacious/releases)
+and extract the folder containing
+[subs2srs.lua](https://raw.githubusercontent.com/Ajatt-Tools/mpvacious/master/subs2srs.lua)
+to your [mpv scripts](https://github.com/mpv-player/mpv/wiki/User-Scripts) directory.
+
+<details>
+
+<summary>Expected directory tree</summary>
+
+```
+~/.config/mpv/scripts
+|-- other script 1
+|-- other script 2
+|-- subs2srs
+|   |-- main.lua
+|   |-- subs2srs.lua
+|   `-- other files

+```
+
+</details>
+
+<details>
+
+<summary>A note for mpv v0.32 and older</summary>
+
+Older versions of `mpv` don't know how to handle user-scripts in subdirectories.
+You need to tell mpv where to look for `mpvacious`.
+
+Open or create  `~/.config/mpv/scripts/modules.lua` and add these lines:
+```
+local mpv_scripts_dir_path = os.getenv("HOME") ..  "/.config/mpv/scripts/"
+package.path = package.path .. ';' .. os.getenv("HOME") .. '/.config/mpv/scripts/subs2srs/?.lua'
+function load(relative_path) dofile(mpv_scripts_dir_path .. relative_path) end
+load("subs2srs/subs2srs.lua")
+```
+
+</details>
+
+**Note:** in [Celluloid](https://www.archlinux.org/packages/community/x86_64/celluloid/)
+user scripts are installed in `/.config/celluloid/scripts/`.
+When following the instructions above, replace `.config/mpv` with `.config/celluloid`
+and optionally `subs2srs` with the name of the folder mpvacious is cloned into.
+
+## Configuration
+
+The config file should be created by the user, if needed.
+
+| OS                 | Config location                                                   |
+|--------------------|-------------------------------------------------------------------|
+| GNU/Linux          | `~/.config/mpv/script-opts/subs2srs.conf`                         |
+| Windows            | `C:/Users/Username/AppData/Roaming/mpv/script-opts/subs2srs.conf` |
+| Windows (portable) | `mpv.exeフォルダ/portable_config/script-opts/subs2srs.conf`           |
+
+If a parameter is not specified
+in the config file, the default value will be used.
+mpv doesn't tolerate spaces before and after `=`.
+
+<p align="center">
+  <a href="https://github.com/Ajatt-Tools/mpvacious/blob/master/.github/RELEASE/subs2srs.conf">Example configuration file</a>
+</p>
+
+If the first field is empty, it will be set contain the string `[empty]`.
+Otherwise, Anki won't allow mpvacious to add new notes.
+This won't happen if the sentence field is first in the note type settings.
+
+**Tip**: Try [our official note type](https://ankiweb.net/shared/info/1557722832)
+if you don't want to configure note fields yourself.
+Alternatively, we have a collection of user-created note types, which you can browse
+[here](https://github.com/Ajatt-Tools/AnkiNoteTypes).
+
+If you are having problems playing media files on older mobile devices,
+set `audio_format` to `mp3` and/or `snapshot_format` to `jpg`.
+Otherwise, I recommend sticking with `opus` for audio,
+and `avif` or `webp` for images,
+as they greatly reduce the size of the generated files.
+
+If you still use AnkiMobile (the [proprietary](https://www.gnu.org/proprietary/) Anki app),
+set `opus_container` to `m4a` or `webm`. I'll allow iOS to play Opus files, while still maintaining
+compatibility with non-Apple devices. For really old iOS devices, set `opus_container` to
+[`caf`](https://en.wikipedia.org/wiki/Core_Audio_Format). CAF plays only on Anki Desktop,
+AnkiWeb in Safari and AnkiMobile, and is really not recommended. (Please note that
+[Lockdown Mode](https://support.apple.com/en-us/105120) completely disables Opus and AVIF support,
+though you may try to add an exception for AnkiMobile.)
+
+If no matter what mpvacious fails to create audio clips and/or snapshots,
+change `use_ffmpeg` to `yes`.
+By using ffmpeg instead of the encoder built in mpv you can work around most encoder issues.
+You need to have ffmpeg installed for this to work.
+
+### Key bindings
+
+The user may change some global key bindings, though this step is not necessary.
+See [Usage](#usage) for the explanation of what they do.
+
+| OS        | Config location                                    |
+|-----------|----------------------------------------------------|
+| GNU/Linux | `~/.config/mpv/input.conf`                         |
+| Windows   | `C:/Users/Username/AppData/Roaming/mpv/input.conf` |
+
+Default bindings:
+
+```
+a            script-binding mpvacious-menu-open
+
+Ctrl+g       script-binding mpvacious-animated-snapshot-toggle
+
+Ctrl+n       script-binding mpvacious-export-note
+
+Ctrl+m       script-binding mpvacious-update-last-note
+Ctrl+M       script-binding mpvacious-overwrite-last-note
+
+g            script-binding mpvacious-quick-card-menu-open
+Alt+g        script-binding mpvacious-quick-card-sel-menu-open
+
+Ctrl+c       script-binding mpvacious-copy-primary-sub-to-clipboard
+Ctrl+C       script-binding mpvacious-copy-secondary-sub-to-clipboard
+Ctrl+t       script-binding mpvacious-autocopy-toggle
+
+H            script-binding mpvacious-sub-seek-back
+L            script-binding mpvacious-sub-seek-forward
+
+Alt+h        script-binding mpvacious-sub-seek-back-pause
+Alt+l        script-binding mpvacious-sub-seek-forward-pause
+
+Ctrl+h       script-binding mpvacious-sub-rewind
+Ctrl+H       script-binding mpvacious-sub-replay
+Ctrl+L       script-binding mpvacious-sub-play-up-to-next
+
+Ctrl+v       script-binding mpvacious-secondary-sid-toggle
+Ctrl+k       script-binding mpvacious-secondary-sid-prev
+Ctrl+j       script-binding mpvacious-secondary-sid-next
+```
+
+**Note:** A capital letter means that you need to press Shift in order to activate the corresponding binding.
+For example, <kbd>Ctrl+M</kbd> actually means <kbd>Ctrl+Shift+m</kbd>.
+mpv accepts both variants in `input.conf`.
+
+## Usage
+
+* [Create a card](howto/create_card.md)
+* [Quick card creation](howto/create_quick_card.md)
+* [Open the "Add" dialog](howto/add_dialog.md)
+* [Usage with Rikaitan](howto/yomichan.md)
+* [Usage with GoldenDict](howto/goldendict.md)
+
+### Global bindings
+
+**Menu:**
+
+* <kbd>a</kbd> - Open `advanced menu`.
+
+**Enable\Disable animation:**
+
+* <kbd>Ctrl+g</kbd> - If animation is enabled, animated snapshots will be generated instead of static images.
+  Animated snapshot are like GIFs (just in a different format)
+  and will capture the video from the start to the end times selected.
+
+**Make a card:**
+
+* <kbd>Ctrl+n</kbd> - Export a card with the currently visible subtitle line on the front.
+Use this when your subs are well-timed,
+and the target sentence doesn't span multiple subs.
+
+**Quick card creation:**
+
+* <kbd>g</kbd> - Quick card creation menu.
+* <kbd>Alt+g</kbd> - Quick card creation, card selection menu.
+
+**Update the last card:**
+
+* <kbd>Ctrl+m</kbd> - Append to the media fields of the newly added Anki card.
+* <kbd>Ctrl+Shift+m</kbd> - Overwrite media fields of the newly added Anki card.
+
+**Clipboard:**
+
+* <kbd>Ctrl+c</kbd> - Copy current subtitle string to the system clipboard.
+* <kbd>Ctrl+t</kbd> - Toggle automatic copying of subtitles to the clipboard.
+
+**Seeking:**
+
+* <kbd>Shift+h</kbd> and <kbd>Shift+l</kbd> - Seek to the previous or the next subtitle.
+* <kbd>Alt+h</kbd> and <kbd>Alt+l</kbd> - Seek to the previous, or the next subtitle, and pause.
+* <kbd>Ctrl+h</kbd> - Seek to the start of the currently visible subtitle. Use it if you missed something.
+* <kbd>Ctrl+Shift+h</kbd> - Replay current subtitle line, and pause.
+* <kbd>Ctrl+Shift+l</kbd> - Play until the end of the next subtitle, and pause. Useful for beginners who need
+  to look up words in each and every dialogue line.
+
+**Secondary subtitles:**
+
+* <kbd>Ctrl+v</kbd> - Toggle visibility.
+* <kbd>Ctrl+k</kbd> - Switch to the previous subtitle if it's not already selected.
+* <kbd>Ctrl+j</kbd> - Switch to the next subtitle if it's not already selected.
+
+### Menu options
+
+Advanced menu has the following options:
+
+* <kbd>f</kbd> - Increment number of cards to update. Only affects note updating, including quick card creation. The number of cards to update is reset to 1 upon updating a note.
+* <kbd>shift+f</kbd> - Decrement number of cards to update.
+
+* <kbd>c</kbd> - Interactive subtitle selection.
+  The range of the currently displayed subtitle line is selected. The selection then grows both ways based on the following displayed lines.
+  It does nothing if there are no subs on screen.
+
+* <kbd>shift+s</kbd> - Set the start time to the current sub. The selection then grows forward based on the following displayed lines.
+  The default selection spans across the range of the currently displayed subtitle line.
+* <kbd>shift+e</kbd> - Set the end time to the current sub. The selection then grows backward based on the following displayed lines.
+  The default selection spans across the range of the currently displayed subtitle line.
+
+Then seek with <kbd>Shift+h</kbd> and <kbd>Shift+l</kbd> to the previous/next line that you want to add.
+Press <kbd>n</kbd> to make the card.
+
+* <kbd>r</kbd> - Forget all previously saved timings and associated dialogs.
+
+* <kbd>z</kbd> and <kbd>Shift+z</kbd> - Adjust subtitle delay.
+
+If above fails, you have to manually set timings.
+* <kbd>s</kbd> - Set the start time. The selection then grows forward based on the following displayed lines.
+The default selection spans across the selected start point and the end of the subtitle line.
+* <kbd>e</kbd> - Set the end time. The selection then grows backward based on the following displayed lines.
+The default selection spans across the selected end point and the start of the subtitle line.
+
+Then, as earlier, press <kbd>n</kbd> to make the card.
+
+**Tip**: change playback speed by pressing <kbd>[</kbd> and <kbd>]</kbd>
+to precisely mark start and end of the phrase.
+
+### My subtitles are not in sync
+
+If subs are badly timed, first, you could try to re-time them.
+Read [Retiming subtitles](https://tatsumoto.neocities.org/blog/retiming-subtitles).
+Or shift timings using key bindings provided by mpv (usually <kbd>z</kbd> and <kbd>Shift+z</kbd>).
+
+### Example sentence card
+
+With the addon you can make cards like this in just a few seconds.
+
+![card-example](https://user-images.githubusercontent.com/69171671/92900057-e102d480-f40e-11ea-8cfc-b00848ca66ff.png)
+
+### Audio cards
+
+It is possible to make a card with just audio, and a picture
+when subtitles for the show you are watching aren't available, for example.
+mpv by default allows you to do a `1` second exact seek by pressing <kbd>Shift+LEFT</kbd> and <kbd>Shift+RIGHT</kbd>.
+Open the mpvacious menu by pressing <kbd>a</kbd>, seek to the position you need, and set the timings.
+Then press <kbd>g</kbd> to invoke the `Add Cards` dialog.
+Here's a [video demonstration](https://redirect.invidious.io/watch?v=BXhyckdHPGE).
+
+If the show is hard-subbed, you can use
+[transformers-ocr](https://tatsumoto.neocities.org/blog/mining-from-manga.html)
+to recognize and add text to the card.
+
+### Secondary subtitles
+
+If you want to add a translation to your cards, and you have the subtitles in that language,
+you can add them as secondary subtitles if you run `mpv` with `--secondary-sid=<sid>` parameter,
+`sid` being the track identifier for the subtitle.
+
+You also need to specify `secondary_field` in the [config file](#Configuration)
+if it is different from the default.
+
+If you want to load secondary subtitles **automatically**, don't modify the run parameters
+and instead set the desired languages in the config file (`secondary_sub_lang` option).
+
+Secondary subtitles will be visible when hovering over the top part of the `mpv` window.

+
+By pressing <kbd>Ctrl</kbd>+<kbd>v</kbd> you can control secondary sid visibility without using the mouse.
+
+### Other tools
+
+If you don't like the default Rikaitan Search tool, try:
+
+* Clipboard Inserter browser add-on
+([chrome](https://chrome.google.com/webstore/detail/clipboard-inserter/deahejllghicakhplliloeheabddjajm))
+([firefox](https://addons.mozilla.org/ja/firefox/addon/clipboard-inserter/))
+* A html page ([1](https://pastebin.com/zDY6s3NK)) ([2](https://pastebin.com/hZ4sawL4))
+to paste the contents of your clipboard to
+
+You can use any html page as long as it has \<body\>\</body\> in it.
+
+### Additional mpv key bindings
+
+I recommend adding these lines to your [input.conf](#key-bindings) for smoother experience.
+```
+# vim-like seeking
+l seek 5
+h seek -5
+j seek -60
+k seek 60
+
+# Cycle between subtitle files
+K cycle sub
+J cycle sub down
+
+# Add/subtract 50 ms delay from subs
+Z add sub-delay +0.05
+z add sub-delay -0.05
+
+# Adjust timing to previous/next subtitle
+X sub-step 1
+x sub-step -1
+```
+
+## Profiles
+
+Mpvacious supports config profiles.
+To make use of them, create a new config file called `subs2srs_profiles.conf`
+in the same folder as your [subs2srs.conf](#Configuration).
+Inside the file, define available profile names (without `.conf`) and the name of the active profile:
+
+```
+profiles=subs2srs,english,german
+active=subs2srs
+```
+
+In the example above, I have three profiles.
+The first one is the default,
+the second one is for learning English,
+the third one is for learning German.
+
+Then in the same folder create config files for each of the defined profiles.
+For example, below is the contents of my `english.conf` file:
+
+```
+deck_name=English sentence mining
+model_name=General
+sentence_field=Question
+audio_field=Audio
+image_field=Extra
+```
+
+You don't have to redefine all settings in the new profile.
+Specify only the ones you want to be different from the default.
+
+To cycle profiles, open the advanced menu by pressing <kbd>a</kbd> and then press <kbd>p</kbd>.
+At any time you can see what profile is active in the menu's status bar.

+# Quick Card Creation
+
+The goal of the quick card creation menu is to streamline a specific flow for media with **well-timed subtitles**:
+
+1) Add a new note to Anki via
+   [Rikaitan](https://tatsumoto.neocities.org/blog/setting-up-yomichan.html)
+   or any other tool that works with AnkiConnect.
+2) Update the note via mpvacious.
+
+To update the most recently added card from the currently visible subtitle line, press <kbd>gg</kbd>.
+
+To make a card from two or more subtitle lines:
+
+1) Press <kbd>g</kbd> to open the quick card creation menu.
+2) Press any number <kbd>[2-9]</kbd>. This number corresponds to the number of lines to create the card from.
+
+Note: <kbd>g1</kbd> is also valid.
+However, <kbd>gg</kbd> is an additional bind to further streamline the most common scenario.
+
+For example,
+<kbd>g2</kbd> creates a card using 2 subtitle lines.
+
+Like the advanced menu, you can also update multiple cards:
+
+1) Press <kbd>Alt+g</kbd> to select the number of cards for quick card creation.
+2) Press any number <kbd>[2-9]</kbd>. This number corresponds to the number of cards to update.
+3) Press any number <kbd>[1-9]</kbd> again. This is the number of lines.
+
+Note: upon completing the note update, the selected number of cards resets back to the default of one.
+
+For example, <kbd>(Alt+g)22</kbd> would update the last 2 notes using 2 subtitle lines.

+# Flatpak notes
+
+We think it's best to never use Flatpak.
+Specifically, try not to use Flatpak to install `mpv` and `anki`.
+Install packages from the official repositories of your distro or from the AUR.
+
+Read the following notes if you still decide to use Flatpak.
+
+Make these changes in Flatseal:
+
+* Enable "Filesystem > All system files"
+  so it could see `wl-copy`.
+  Unfortunately, there's no option to provide only a specific system file.
+* Add `~/.var/app/net.ankiweb.Anki` to "Filesystem > Other Files"
+  so mpvacious could add encoded snapshots and audio to Anki.
+* Add `PATH=/home/USERNAME/.local/bin:/home/USERNAME/bin:/app/bin:/usr/bin:/run/host/usr/bin` to "Environment > Variables".
+  There's no option to add a path to `PATH` in Flatseal,
+  so I opened container,
+  saved it's PATH and added `/run/host/usr/bin`
+  so mpvacuous could access `wl-copy`.
+* Enable "Shared > Network".
+  It's enabled by default, but anyway.
+
+The mpv config root is `~/.var/app/io.mpv.Mpv/config/mpv`
+
+* `~/.var/app/io.mpv.Mpv/config/mpv/scripts`
+* `~/.var/app/io.mpv.Mpv/config/mpv/script-opts`

+# Modifying cards added with GoldenDict
+
+You can add a card first using GoldenDict,
+and then append an audio clip and a picture to it.
+
+**Note:** the only version of GoldenDict that can create Anki cards with configurable fields is
+[xiaoyifang's goldendict](https://github.com/xiaoyifang/goldendict-ng).
+Read [Setting up GoldenDict](https://tatsumoto-ren.github.io/blog/setting-up-goldendict.html) and
+[How to connect with Anki](https://github.com/xiaoyifang/goldendict-ng/blob/staged/website/docs/topic_anki.md)
+if you are new to GoldenDict.
+
+To send subtitles from `mpv` directly to GoldenDict,
+append the following line to `subs2srs.conf`:
+
+```
+autoclip_method=goldendict
+```
+
+**Note:** If `goldendict` is not in the PATH,
+you have to [add it to the PATH](https://wiki.archlinux.org/title/Environment_variables#Per_user).
+
+1) Press <kbd>a</kbd> to open `advanced menu`.
+2) Press <kbd>t</kbd> to toggle the `autoclip` option.
+
+Now as subtitles appear on the screen,
+they will be immediately sent to GoldenDict instead of the system clipboard.
+
+1) Open GoldenDict.
+2) Play a video in `mpv`.
+3) When you find an unknown word,
+   select the definition text,
+   right-click and select "send word to anki" to make a card,
+   or press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>N</kbd>.
+4) Go back to mpv and add an image and an audio clip
+   to the card you've just made by pressing <kbd>m</kbd> while the `advanced menu` is open.
+   Pressing <kbd>Shift+m</kbd> will overwrite any existing data in media fields.
+
+https://github.com/Ajatt-Tools/mpvacious/assets/69171671/0fc02d24-d320-4d2c-b7a9-cb478e9f0067
+
+Don't forget to set the right timings and join lines together
+if the sentence is split between multiple subs.
+To do it, enter interactive selection by pressing <kbd>c</kbd>
+and seek to the next or previous subtitle.
+
+To pair Mecab and GoldenDict, install [gd-tools](https://github.com/Ajatt-Tools/gd-tools).

+* curl
+* xclip (when running X11)
+* wl-copy (when running Wayland)
+
+Usage:
+1. Change `config` according to your needs
+* Config path: ~/.config/mpv/script-opts/subs2srs.conf
+* Config file isn't created automatically.
+
+2. Open a video
+
+3. Use key bindings to manipulate the script
+* Open mpvacious menu - `a`
+* Create a note from the current subtitle line - `Ctrl + n`
+
+For complete usage guide, see <https://github.com/Ajatt-Tools/mpvacious/blob/master/README.md>
