+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at admin@asciinema.org. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Terminal session recorder and the best companion of
+[asciinema.org](https://asciinema.org).
+
+[![demo](https://asciinema.org/a/335480.svg)](https://asciinema.org/a/335480?autoplay=1)
+
+asciinema _[as-kee-nuh-muh]_ is a free and open source solution for recording
+terminal sessions and sharing them on the web.
+
+Shout-out to our Platinum [sponsors](https://github.com/sponsors/ku1ik), whose
+financial support helps keep the project alive:
+
+[<img src="./.github/sponsor-logos/dashcam/logo-on-light.png" width="200" />](https://dashcam.io?utm_source=asciinemagithub)
+
+## Quick intro
+
+asciinema lets you easily record terminal sessions and replay
+them in a terminal as well as in a web browser.
+
+Install latest version ([other installation options](#installation))
+using [pipx](https://pypa.github.io/pipx/) (if you have it):
+
+```sh
+pipx install asciinema
+```
+
+If you don't have pipx, install using pip with your preferred Python version:
+
+```sh
+python3 -m pip install asciinema
+```
+
+Record your first session:
+
+```sh
+asciinema rec first.cast
+```
+
+Now replay it with double speed:
+
+```sh
+asciinema play -s 2 first.cast
+```
+
+Or with normal speed but with idle time limited to 2 seconds:
+
+```sh
+asciinema play -i 2 first.cast
+```
+
+You can pass `-i 2` to `asciinema rec` as well, to set it permanently on a
+recording. Idle time limiting makes the recordings much more interesting to
+watch. Try it.
+
+If you want to watch and share it on the web, upload it:
+
+```sh
+asciinema upload first.cast
+```
+
+The above uploads it to [asciinema.org](https://asciinema.org), which is a
+default [asciinema-server](https://github.com/asciinema/asciinema-server)
+instance, and prints a secret link you can use to watch your recording in a web
+browser.
+
+You can record and upload in one step by omitting the filename:
+
+```sh
+asciinema rec
+```
+
+You'll be asked to confirm the upload when the recording is done. Nothing is
+sent anywhere without your consent.
+
+These are the basics, but there's much more you can do. The following sections
+cover installation, usage and hosting of the recordings in more detail. Also,
+checkout [agg](https://github.com/asciinema/agg) if you're interested in GIF generation.
+
+## Installation
+
+### Python package from PyPI
+
+[pypi]: https://pypi.python.org/pypi/asciinema
+
+asciinema is available on [PyPI] and can be installed with
+[pipx](https://pypa.github.io/pipx/) (if you have it) or with pip (Python 3
+with setuptools required):
+
+```sh
+pipx install asciinema
+```
+
+Or with pip (using your preferred Python version):
+
+```sh
+python3 -m pip install asciinema
+```
+
+Installing from [PyPI] is the recommended way of installation, which gives you the latest released version.
+
+### Native packages
+
+asciinema is included in repositories of most popular package managers on Mac OS
+X, Linux and FreeBSD. Look for package named `asciinema`. See the
+[list of available packages](https://asciinema.org/docs/installation).
+
+### Running latest version from source code checkout
+
+If you can't use Python package or native package for your OS is outdated you
+can clone the repo and run asciinema straight from the checkout.
+
+Clone the repo:
+
+```sh
+git clone https://github.com/asciinema/asciinema.git
+cd asciinema
+```
+
+If you want latest stable version:
+
+```sh
+git checkout master
+```
+
+If you want current development version:
+
+```sh
+git checkout develop
+```
+
+Then run it with:
+
+```sh
+python3 -m asciinema --version
+```
+
+### Docker image
+
+asciinema Docker image is based on [Ubuntu
+22.04](https://releases.ubuntu.com/22.04/) and has the latest version of
+asciinema recorder pre-installed.
+
+```sh
+docker pull ghcr.io/asciinema/asciinema
+```
+
+When running it don't forget to allocate a pseudo-TTY (`-t`), keep STDIN open
+(`-i`) and mount config directory volume (`-v`):
+
+```sh
+docker run --rm -it -v "${HOME}/.config/asciinema:/root/.config/asciinema" ghcr.io/asciinema/asciinema rec
+```
+
+Container's entrypoint is set to `/usr/local/bin/asciinema` so you can run the
+container with any arguments you would normally pass to `asciinema` binary (see
+Usage section for commands and options).
+
+There's not much software installed in this image though. In most cases you may
+want to install extra programs before recording. One option is to derive new
+image from this one (start your custom Dockerfile with `FROM
+ghcr.io/asciinema/asciinema`). Another option is to start the container with
+`/bin/bash` as the entrypoint, install extra packages and manually start
+`asciinema rec`:
+
+```console
+docker run --rm -it -v "${HOME}/.config/asciinema:/root/.config/asciinema" --entrypoint=/bin/bash ghcr.io/asciinema/asciinema rec
+root@6689517d99a1:~# apt-get install foobar
+root@6689517d99a1:~# asciinema rec
+```
+
+It is also possible to run the docker container as a non-root user, which has
+security benefits. You can specify a user and group id at runtime to give the
+application permission similar to the calling user on your host.
+
+```sh
+docker run --rm -it \
+    --env=ASCIINEMA_CONFIG_HOME="/run/user/$(id -u)/.config/asciinema" \
+    --user="$(id -u):$(id -g)" \
+    --volume="${HOME}/.config/asciinema:/run/user/$(id -u)/.config/asciinema:rw" \
+    --volume="${PWD}:/data:rw" \
+    --workdir='/data' \
+    ghcr.io/asciinema/asciinema rec
+```
+
+## Usage
+
+asciinema is composed of multiple commands, similar to `git`, `apt-get` or
+`brew`.
+
+When you run `asciinema` with no arguments help message is displayed, listing
+all available commands with their options.
+
+### `rec [filename]`
+
+**Record terminal session.**
+
+By running `asciinema rec [filename]` you start a new recording session. The
+command (process) that is recorded can be specified with `-c` option (see
+below), and defaults to `$SHELL` which is what you want in most cases.
+
+You can temporarily pause the capture of your terminal by pressing
+<kbd>Ctrl+\\</kbd>.  This is useful when you want to execute some commands during
+the recording session that should not be captured (e.g. pasting secrets). Resume
+by pressing <kbd>Ctrl+\\</kbd> again. When pausing desktop notification is
+displayed so you're sure the sensitive output won't be captured in the
+recording.
+
+Recording finishes when you exit the shell (hit <kbd>Ctrl+D</kbd> or type
+`exit`). If the recorded process is not a shell then recording finishes when
+the process exits.
+
+If the `filename` argument is omitted then (after asking for confirmation) the
+resulting asciicast is uploaded to
+[asciinema-server](https://github.com/asciinema/asciinema-server) (by default to
+asciinema.org), where it can be watched and shared.
+
+If the `filename` argument is given then the resulting recording (called
+[asciicast](doc/asciicast-v2.md)) is saved to a local file. It can later be
+replayed with `asciinema play <filename>` and/or uploaded to asciinema server
+with `asciinema upload <filename>`.
+
+`ASCIINEMA_REC=1` is added to recorded process environment variables. This
+can be used by your shell's config file (`.bashrc`, `.zshrc`) to alter the
+prompt or play a sound when the shell is being recorded.
+
+Available options:
+
+- `--stdin` - Enable stdin (keyboard) recording (see below)
+- `--append` - Append to existing recording
+- `--raw` - Save raw STDOUT output, without timing information or other metadata
+- `--overwrite` - Overwrite the recording if it already exists
+- `-c, --command=<command>` - Specify command to record, defaults to $SHELL
+- `-e, --env=<var-names>` - List of environment variables to capture, defaults
+  to `SHELL,TERM`
+- `-t, --title=<title>` - Specify the title of the asciicast
+- `-i, --idle-time-limit=<sec>` - Limit recorded terminal inactivity to max `<sec>` seconds
+- `--cols=<n>` - Override terminal columns for recorded process
+- `--rows=<n>` - Override terminal rows for recorded process
+- `-y, --yes` - Answer "yes" to all prompts (e.g. upload confirmation)
+- `-q, --quiet` - Be quiet, suppress all notices/warnings (implies -y)
+
+Stdin recording allows for capturing of all characters typed in by the user in
+the currently recorded shell. This may be used by a player (e.g.
+[asciinema-player](https://github.com/asciinema/asciinema-player)) to display
+pressed keys. Because it's basically key-logging (scoped to a single shell
+instance), it's disabled by default, and has to be explicitly enabled via
+`--stdin` option.
+
+### `play <filename>`
+
+**Replay recorded asciicast in a terminal.**
+
+This command replays given asciicast (as recorded by `rec` command) directly in
+your terminal.
+
+Following keyboard shortcuts are available by default:
+
+- <kbd>Space</kbd> - toggle pause,
+- <kbd>.</kbd> - step through a recording a frame at a time (when paused),
+- <kbd>Ctrl+C</kbd> - exit.
+
+See "Configuration file" section for information on how to customize the
+keyboard shortcuts.
+
+Playing from a local file:

+
+Available options:
+
+- `-i, --idle-time-limit=<sec>` - Limit replayed terminal inactivity to max `<sec>` seconds
+- `-s, --speed=<factor>` - Playback speed (can be fractional)
+- `-l, --loop` - Play in a loop
+- `-m, --pause-on-markers` - Automatically pause on [markers](#markers)
+- `--stream=<stream>` - Select stream to play (see below)
+- `--out-fmt=<format>` - Select output format (see below)
+
+By default the output stream (`o`) is played. This is what you want in most
+cases.  If you recorded the input stream (`i`) with `asciinema rec --stdin` then
+you can replay it with `asciinema play --stream=i <filename>`.
+
+By default the selected stream is written to stdout in original, raw data form.
+This is also what you want in majority of cases. However you can change the
+output format to asciicast (newline delimited JSON) with `asciinema play
+--out-fmt=asciicast <filename>`. This allows delegating actual rendering to
+another place (e.g. outside of your terminal) by piping output of `asciinema
+play` to a tool of your choice.
+
+> For the best playback experience it is recommended to run `asciinema play` in
+> a terminal of dimensions not smaller than the one used for recording, as
+> there's no "transcoding" of control sequences for new terminal size.
+
+### `cat <filename>`
+
+**Print full output of recorded asciicast to a terminal.**
+
+While `asciinema play <filename>` replays the recorded session using timing
+information saved in the asciicast, `asciinema cat <filename>` dumps the full
+output (including all escape sequences) to a terminal immediately.
+
+`asciinema cat existing.cast >output.txt` gives the same result as recording via
+`asciinema rec --raw output.txt`.
+
+### `upload <filename>`
+
+**Upload recorded asciicast to asciinema.org site.**
+
+This command uploads given asciicast (recorded by `rec` command) to
+asciinema.org, where it can be watched and shared.
+
+`asciinema rec demo.cast` + `asciinema play demo.cast` + `asciinema upload demo.cast` is a nice combo if you want to review an asciicast before
+publishing it on asciinema.org.
+
+### `auth`
+
+**Link your install ID with your asciinema.org user account.**
+
+If you want to manage your recordings (change title/theme, delete) at
+asciinema.org you need to link your "install ID" with asciinema.org user
+account.
+
+This command displays the URL to open in a web browser to do that. You may be
+asked to log in first.
+
+Install ID is a random ID ([UUID
+v4](https://en.wikipedia.org/wiki/Universally_unique_identifier)) generated
+locally when you run asciinema for the first time, and saved at
+`$HOME/.config/asciinema/install-id`. Its purpose is to connect local machine
+with uploaded recordings, so they can later be associated with asciinema.org
+account. This way we decouple uploading from account creation, allowing them to
+happen in any order.
+
+> A new install ID is generated on each machine and system user account you use
+> asciinema on, so in order to keep all recordings under a single asciinema.org
+> account you need to run `asciinema auth` on all of those machines.
+
+> asciinema versions prior to 2.0 confusingly referred to install ID as "API
+> token".
+
+## Markers
+
+Markers allow marking specific time locations in a recording, which can be used
+for navigation, as well as for automatic pausing of the playback.
+
+Markers can be added to a recording in several ways:
+
+- while you are recording, by pressing a configured hotkey, see [add_marker_key
+  config option](#configuration-file)
+- for existing recording, by inserting marker events (`"m"`) in the asciicast
+  file, see [marker event](doc/asciicast-v2.md#m---marker)
+
+When replaying a recording with `asciinema play` you can enable
+auto-pause-on-marker behaviour with `-m`/`--pause-on-markers` option (it's off
+by default). When a marker is encountered, the playback automatically pauses and
+can be resumed by pressing space bar key. The playback continues until next
+marker is encountered. You can also fast-forward to the next marker by pressing
+`]` key (when paused).
+
+Markers can be useful in e.g. live demos: you can create a recording with
+markers, then play it back during presentation, and have it stop wherever you
+want to explain terminal contents in more detail.
+
+## Hosting the recordings on the web
+
+As mentioned in the `Usage > rec` section above, if the `filename` argument to
+`asciinema rec` is omitted then the recorded asciicast is uploaded to
+[asciinema.org](https://asciinema.org). You can watch it there and share it via
+secret URL.
+
+If you prefer to host the recordings yourself, you can do so by either:
+
+- recording to a file (`asciinema rec demo.cast`), and using [asciinema's
+  standalone web
+  player](https://github.com/asciinema/asciinema-player#self-hosting-quick-start)
+  in your HTML page, or
+- setting up your own
+  [asciinema-server](https://github.com/asciinema/asciinema-server) instance,
+  and [setting API URL
+  accordingly](https://github.com/asciinema/asciinema-server/wiki/Installation-guide#using-asciinema-recorder-with-your-instance).
+
+## Configuration file
+
+You can configure asciinema by creating config file at
+`$HOME/.config/asciinema/config`.
+
+Configuration is split into sections (`[api]`, `[record]`, `[play]`). Here's a
+list of all available options for each section:
+
+```ini
+[api]
+
+; API server URL, default: https://asciinema.org
+; If you run your own instance of asciinema-server then set its address here
+; It can also be overriden by setting ASCIINEMA_API_URL environment variable
+url = https://asciinema.example.com
+
+[record]
+
+; Command to record, default: $SHELL
+command = /bin/bash -l
+
+; Enable stdin (keyboard) recording, default: no
+stdin = yes
+
+; List of environment variables to capture, default: SHELL,TERM
+env = SHELL,TERM,USER
+
+; Limit recorded terminal inactivity to max n seconds, default: off
+idle_time_limit = 2
+
+; Answer "yes" to all interactive prompts, default: no
+yes = true
+
+; Be quiet, suppress all notices/warnings, default: no
+quiet = true
+
+; Define hotkey for pausing recording (suspending capture of output),
+; default: C-\ (control + backslash)
+pause_key = C-p
+
+; Define hotkey for adding a marker, default: none
+add_marker_key = C-x
+
+; Define hotkey prefix key - when defined other recording hotkeys must
+; be preceeded by it, default: no prefix
+prefix_key = C-a
+
+[play]
+
+; Playback speed (can be fractional), default: 1
+speed = 2
+
+; Limit replayed terminal inactivity to max n seconds, default: off
+idle_time_limit = 1
+
+; Define hotkey for pausing/resuming playback,
+; default: space
+pause_key = p
+
+; Define hotkey for stepping through playback, a frame at a time,
+; default: . (dot)
+step_key = s
+
+; Define hotkey for jumping to the next marker,
+; default: ]
+next_marker_key = m
+
+[notifications]
+; Desktop notifications are displayed on certain occasions, e.g. when
+; pausing/resuming the capture of terminal with C-\ keyboard shortcut.
+
+; Should desktop notifications be enabled, default: yes
+enabled = no
+
+; Custom notification command
+; asciinema automatically detects available desktop notification system
+; (notify-send on GNU/Linux, osacript/terminal-notifier on macOS). Custom
+; command can be used if needed.
+; When invoked, environment variable $TEXT contains notification text, while
+; $ICON_PATH contains path to the asciinema logo image.
+command = tmux display-message "$TEXT"
+```
+
+A very minimal config file could look like that:
+
+```ini
+[record]
+idle_time_limit = 2
+```
+
+Config directory location can be changed by setting `$ASCIINEMA_CONFIG_HOME`
+environment variable.
+
+If `$XDG_CONFIG_HOME` is set on Linux then asciinema uses
+`$XDG_CONFIG_HOME/asciinema` instead of `$HOME/.config/asciinema`.
+
+> asciinema versions prior to 1.1 used `$HOME/.asciinema`. If you have it
+> there you should `mv $HOME/.asciinema $HOME/.config/asciinema`.

+# asciicast file format (version 1)
+
+asciicast file is JSON file containing meta-data like duration or title of the
+recording, and the actual content printed to terminal's stdout during
+recording.
+
+Version 1 of the format was used by the asciinema recorder versions 1.0 up to 1.4.
+
+## Attributes
+
+Every asciicast includes the following set of attributes:
+
+* `version` - set to 1,
+* `width` - terminal width (number of columns),
+* `height` - terminal height (number of rows),
+* `duration` - total duration of asciicast as floating point number,
+* `command` - command that was recorded, as given via `-c` option to `rec`,
+* `title` - title of the asciicast, as given via `-t` option to `rec`,
+* `env` - map of environment variables useful for debugging playback problems,
+* `stdout` - array of "frames", see below.
+
+### Frame
+
+Frame represents an event of printing new data to terminal's stdout. It is a 2
+element array containing **delay** and **data**.
+
+**Delay** is the number of seconds that elapsed since the previous frame (or
+since the beginning of the recording in case of the 1st frame) represented as
+a floating point number, with microsecond precision.
+
+**Data** is a string containing the data that was printed to a terminal in a
+given frame. It has to be valid, UTF-8 encoded JSON string as described in
+[JSON RFC section 2.5](http://www.ietf.org/rfc/rfc4627.txt), with all
+non-printable Unicode codepoints encoded as `\uXXXX`.
+
+For example, frame `[5.4321, "foo\rbar\u0007..."]` means there was 5 seconds of
+inactivity between previous printing and printing of `foo\rbar\u0007...`.
+
+## Example asciicast
+
+A very short asciicast may look like this:
+
+    {
+      "version": 1,
+      "width": 80,
+      "height": 24,
+      "duration": 1.515658,
+      "command": "/bin/zsh",
+      "title": "",
+      "env": {
+        "TERM": "xterm-256color",
+        "SHELL": "/bin/zsh"
+      },
+      "stdout": [
+        [
+          0.248848,
+          "\u001b[1;31mHello \u001b[32mWorld!\u001b[0m\n"
+        ],
+        [
+          1.001376,
+          "I am \rThis is on the next line."
+        ]
+      ]
+    }

+# asciicast file format (version 2)
+
+asciicast v2 file is [newline-delimited JSON](http://jsonlines.org/) file where:
+
+* __first line__ contains header (initial terminal size, timestamp and other
+  meta-data), encoded as JSON object,
+* __all following lines__ form an event stream, _each line_ representing a
+  separate event, encoded as 3-element JSON array.
+
+Example file:
+
+```json
+{"version": 2, "width": 80, "height": 24, "timestamp": 1504467315, "title": "Demo", "env": {"TERM": "xterm-256color", "SHELL": "/bin/zsh"}}
+[0.248848, "o", "\u001b[1;31mHello \u001b[32mWorld!\u001b[0m\n"]
+[1.001376, "o", "That was ok\rThis is better."]
+[1.500000, "m", ""]
+[2.143733, "o", "Now... "]
+[4.050000, "r", "80x24"]
+[6.541828, "o", "Bye!"]
+```
+
+Suggested file extension is `.cast`, suggested media type is
+`application/x-asciicast`.
+
+## Header
+
+asciicast header is JSON-encoded object containing recording meta-data.
+
+### Required header attributes:
+
+#### `version`
+
+Must be set to `2`. Integer.
+
+#### `width`
+
+Initial terminal width (number of columns). Integer.
+
+#### `height`
+
+Initial terminal height (number of rows). Integer.
+
+### Optional header attributes:
+
+#### `timestamp`
+
+Unix timestamp of the beginning of the recording session. Integer.
+
+#### `duration`
+
+Duration of the whole recording in seconds (when it's known upfront). Float.
+
+#### `idle_time_limit`
+
+Idle time limit, as given via `-i` option to `asciinema rec`. Float.
+
+This should be used by an asciicast player to reduce all terminal inactivity
+(delays between frames) to maximum of `idle_time_limit` value.
+
+#### `command`
+
+Command that was recorded, as given via `-c` option to `asciinema rec`. String.
+
+#### `title`
+
+Title of the asciicast, as given via `-t` option to `asciinema rec`. String.
+
+#### `env`
+
+Map of captured environment variables. Object (String -> String).
+
+Example env:
+
+```json
+"env": {
+  "SHELL": "/bin/bash",
+  "TERM": "xterm-256color"
+}
+```
+
+> Official asciinema recorder captures only `SHELL` and `TERM` by default. All
+> implementations of asciicast-compatible terminal recorder should not capture
+> any additional environment variables unless explicitly permitted by the user.
+
+#### `theme`
+
+Color theme of the recorded terminal. Object, with the following attributes:
+
+- `fg` - normal text color,
+- `bg` - normal background color,
+- `palette` - list of 8 or 16 colors, separated by colon character.
+
+All colors are in the CSS `#rrggbb` format.
+
+Example theme:
+
+```json
+"theme": {
+  "fg": "#d0d0d0",
+  "bg": "#212121",
+  "palette": "#151515:#ac4142:#7e8e50:#e5b567:#6c99bb:#9f4e85:#7dd6cf:#d0d0d0:#505050:#ac4142:#7e8e50:#e5b567:#6c99bb:#9f4e85:#7dd6cf:#f5f5f5"
+}
+```
+
+> A specific technique of obtaining the colors from a terminal (using xrdb,
+> requesting them from a terminal via special escape sequences etc) doesn't
+> matter as long as the recorder can save it in the above format.
+
+## Event stream
+
+Each element of the event stream is a 3-tuple encoded as JSON array:
+
+    [time, code, data]
+
+Where:
+
+* `time` (float) - indicates when the event happened, represented as the number
+  of seconds since the beginning of the recording session,
+* `code` (string) - specifies type of event, one of: `"o"`, `"i"`, `"m"`, `"r"`
+* `data` (any) - event specific data, described separately for each event
+  code.
+
+For example, let's look at the following line:
+
+    [1.001376, "o", "Hello world"]
+
+It represents:
+
+* output (code `o`),
+* of text `Hello world`,
+* which happened `1.001376` sec after the start of the recording session.
+
+### Supported event codes
+
+This section describes the event codes supported in asciicast v2 format.
+
+The list is open to extension, and new event codes may be added in both the
+current and future versions of the format. For example, we may add new event
+code for text overlay (subtitles display).
+
+A tool which interprets the event stream (web/cli player, post-processor) should
+ignore (or pass through) event codes it doesn't understand or doesn't care
+about.
+
+#### "o" - output, data written to a terminal
+
+Event of code `"o"` represents printing new data to a terminal.
+
+`data` is a string containing the data that was printed. It must be valid, UTF-8
+encoded JSON string as described in [JSON RFC section
+2.5](http://www.ietf.org/rfc/rfc4627.txt), with any non-printable Unicode
+codepoints encoded as `\uXXXX`.
+
+#### "i" - input, data read from a terminal
+
+Event of code `"i"` represents character typed in by the user, or more
+specifically, raw data sent from a terminal emulator to stdin of the recorded
+program (usually shell).
+
+`data` is a string containing captured ASCII character representing a key, or a
+control character like `"\r"` (enter), `"\u0001"` (ctrl-a), `"\u0003"` (ctrl-c),
+etc. Like with `"o"` event, it's UTF-8 encoded JSON string, with any
+non-printable Unicode codepoints encoded as `\uXXXX`.
+
+> Official asciinema recorder doesn't capture keyboard input by default. All
+> implementations of asciicast-compatible terminal recorder should not capture
+> it either unless explicitly requested by the user.
+
+#### "m" - marker
+
+Event of code `"m"` represents a marker.
+
+When marker is encountered in the event stream and "pause on markers"
+functionality of the player is enabled, the playback should pause, and wait for
+the user to resume.
+
+`data` can be used to annotate a marker. Annotations may be used to e.g.
+show a list of named "chapters".
+
+#### "r" - resize
+
+Event of code `"r"` represents terminal resize.
+
+Those are captured in response to `SIGWINCH` signal.
+
+`data` contains new terminal size (columns + rows) formatted as
+`"{COLS}x{ROWS}"`, e.g. `"80x24"`.
+
+## Notes on compatibility
+
+Version 2 of asciicast file format solves several problems which couldn't be
+easily fixed in the old format:
+
+* minimal memory usage when recording and replaying arbitrarily long sessions -
+  disk space is the only limit,
+* when the recording session is interrupted (computer crash, accidental close of
+  terminal window) you don't lose the whole recording,
+* it's real-time streaming friendly.
+
+Due to file structure change (standard JSON => newline-delimited JSON) version 2
+is not backwards compatible with version 1. Support for v2 has been added in:
+
+* [asciinema terminal recorder](https://github.com/asciinema/asciinema) - 2.0.0
+* [asciinema web player](https://github.com/asciinema/asciinema-player) - 2.6.0
+* [asciinema server](https://github.com/asciinema/asciinema-server) - v20171105

+\f[B]asciinema\f[R] \f[I]command\f[R] [\f[I]options\f[R]]
+[\f[I]args\f[R]]
+.SH DESCRIPTION
+.PP
+asciinema lets you easily record terminal sessions, replay them in a
+terminal as well as in a web browser and share them on the web.
+asciinema is Free and Open Source Software licensed under the GNU
+General Public License v3.
+.SH COMMANDS
+.PP
+asciinema is composed of multiple commands, similar to \f[V]git\f[R],
+\f[V]apt-get\f[R] or \f[V]brew\f[R].
+.PP
+When you run \f[B]asciinema\f[R] with no arguments a help message is
+displayed, listing all available commands with their options.
+.SS rec [\f[I]filename\f[R]]
+.PP
+Record terminal session.
+.PP
+By running \f[B]asciinema rec [filename]\f[R] you start a new recording
+session.
+The command (process) that is recorded can be specified with
+\f[B]-c\f[R] option (see below), and defaults to \f[B]$SHELL\f[R] which
+is what you want in most cases.
+.PP
+You can temporarily pause recording of terminal by pressing Ctrl+\[rs].
+This is useful when you want to execute some commands during the
+recording session that should not be captured (e.g.\ pasting secrets).
+Resume by pressing Ctrl+\[rs] again.
+.PP
+Recording finishes when you exit the shell (hit Ctrl+D or type
+\f[V]exit\f[R]).
+If the recorded process is not a shell then recording finishes when the
+process exits.
+.PP
+If the \f[I]filename\f[R] argument is omitted then (after asking for
+confirmation) the resulting asciicast is uploaded to
+asciinema-server (https://github.com/asciinema/asciinema-server) (by
+default to asciinema.org), where it can be watched and shared.
+.PP
+If the \f[I]filename\f[R] argument is given then the resulting recording
+(called asciicast) is saved to a local file.
+It can later be replayed with \f[B]asciinema play <filename>\f[R] and/or
+uploaded to asciinema server with \f[B]asciinema upload <filename>\f[R].
+.PP
+\f[B]ASCIINEMA_REC=1\f[R] is added to recorded process environment
+variables.
+This can be used by your shell\[cq]s config file (\f[V].bashrc\f[R],
+\f[V].zshrc\f[R]) to alter the prompt or play a sound when the shell is
+being recorded.
+.TP
+Available options:
+\
+.RS
+.TP
+\f[V]--stdin\f[R]
+Enable stdin (keyboard) recording (see below)
+.TP
+\f[V]--append\f[R]

+.TP
+\f[V]-q, --quiet\f[R]
+Be quiet, suppress all notices/warnings (implies \f[B]-y\f[R])
+.RE
+.PP
+Stdin recording allows for capturing of all characters typed in by the
+user in the currently recorded shell.
+This may be used by a player (e.g.
+asciinema-player (https://github.com/asciinema/asciinema-player)) to
+display pressed keys.
+Because it\[cq]s basically a key-logging (scoped to a single shell
+instance), it\[cq]s disabled by default, and has to be explicitly
+enabled via \f[B]\[en]stdin\f[R] option.
+.SS play <\f[I]filename\f[R]>
+.PP
+Replay recorded asciicast in a terminal.
+.PP
+This command replays a given asciicast (as recorded by \f[B]rec\f[R]
+command) directly in your terminal.

+.PP
+Recommendation: run `asciinema play' in a terminal of dimensions not

+\[lq]transcoding\[rq] of control sequences for the new terminal size.
+.SS cat <\f[I]filename\f[R]>
+.PP
+Print full output of recorded asciicast to a terminal.
+.PP
+While \f[B]asciinema play \f[R] replays the recorded session using

+dumps the full output (including all escape sequences) to a terminal
+immediately.
+.PP
+\f[B]asciinema cat existing.cast >output.txt\f[R] gives the same result
+as recording via \f[B]asciinema rec --raw output.txt\f[R].
+.SS upload <\f[I]filename\f[R]>
+.PP
+Upload recorded asciicast to asciinema.org site.
+.PP
+This command uploads given asciicast (recorded by \f[B]rec\f[R] command)
+to asciinema.org, where it can be watched and shared.
+.PP
+\f[B]asciinema rec demo.cast\f[R] + \f[B]asciinema play demo.cast\f[R] +
+\f[B]asciinema upload demo.cast\f[R] is a nice combo if you want to
+review an asciicast before publishing it on asciinema.org.
+.SS auth
+.PP
+Link and manage your install ID with your asciinema.org user account.
+.PP
+If you want to manage your recordings (change title/theme, delete) at
+asciinema.org you need to link your \[lq]install ID\[rq] with your
+asciinema.org user account.
+.PP
+This command displays the URL to open in a web browser to do that.
+You may be asked to log in first.
+.PP
+Install ID is a random ID (UUID
+v4 (https://en.wikipedia.org/wiki/Universally_unique_identifier))
+generated locally when you run asciinema for the first time, and saved
+at \f[B]$HOME/.config/asciinema/install-id\f[R].
+It\[cq]s purpose is to connect local machine with uploaded recordings,
+so they can later be associated with asciinema.org account.
+This way we decouple uploading from account creation, allowing them to
+happen in any order.
+.PP
+Note: A new install ID is generated on each machine and system user
+account you use asciinema on.
+So in order to keep all recordings under a single asciinema.org account
+you need to run \f[B]asciinema auth\f[R] on all of those machines.
+If you\[cq]re already logged in on asciinema.org website and you run
+`asciinema auth' from a new computer then this new device will be linked
+to your account.
+.PP
+While you CAN synchronize your config file (which keeps the API token)
+across all your machines so all use the same token, that\[cq]s not
+necessary.
+You can assign new tokens to your account from as many machines as you
+want.
+.PP
+Note: asciinema versions prior to 2.0 confusingly referred to install ID
+as \[lq]API token\[rq].
+.SH EXAMPLES
+.PP
+Record your first session:
+.IP
+.nf
+\f[C]
+asciinema rec first.cast
+\f[R]
+.fi
+.PP
+End your session:
+.IP
+.nf
+\f[C]
+exit
+\f[R]
+.fi
+.PP
+Now replay it with double speed:
+.IP
+.nf
+\f[C]
+asciinema play -s 2 first.cast
+\f[R]
+.fi
+.PP
+Or with normal speed but with idle time limited to 2 seconds:
+.IP
+.nf
+\f[C]
+asciinema play -i 2 first.cast
+\f[R]
+.fi
+.PP
+You can pass \f[B]-i 2\f[R] to \f[B]asciinema rec\f[R] as well, to set
+it permanently on a recording.
+Idle time limiting makes the recordings much more interesting to watch,
+try it.
+.PP
+If you want to watch and share it on the web, upload it:
+.IP
+.nf
+\f[C]
+asciinema upload first.cast
+\f[R]
+.fi
+.PP
+The above uploads it to <https://asciinema.org>, which is a default
+asciinema-server (<https://github.com/asciinema/asciinema-server>)
+instance, and prints a secret link you can use to watch your recording
+in a web browser.
+.PP
+You can record and upload in one step by omitting the filename:
+.IP
+.nf
+\f[C]
+asciinema rec
+\f[R]
+.fi
+.PP
+You\[cq]ll be asked to confirm the upload when the recording is done, so
+nothing is sent anywhere without your consent.
+.SS Tricks
+.TP
+Record slowly, play faster:
+First record a session where you can take your time to type slowly what
+you want to show in the recording:
+.RS
+.IP
+.nf
+\f[C]
+asciinema rec initial.cast
+\f[R]
+.fi
+.PP
+Then record the replay of `initial.cast' as `final.cast', but with five
+times the initially recorded speed, with all pauses capped to two
+seconds and with a title set as \[lq]My fancy title\[rq]::
+.IP
+.nf
+\f[C]
+asciinema rec -c \[dq]asciinema play -s 5 -i 2 initial.cast\[dq] -t \[dq]My fancy title\[dq] final.cast
+\f[R]
+.fi
+.RE
+.TP
+Play from \f[I]\f[VI]stdin\f[I]\f[R]:
+\
+.RS
+.PP
+cat /path/to/asciicast.json | asciinema play -
+.RE
+.TP
+Play file from remote host accessible with SSH:
+\
+.RS
+.PP
+ssh user\[at]host cat /path/to/asciicat.json | asciinema play -
+.RE
+.SH ENVIRONMENT
+.TP
+\f[B]ASCIINEMA_API_URL\f[R]
+This variable allows overriding asciinema-server URL (which defaults to
+https://asciinema.org) in case you\[cq]re running your own
+asciinema-server instance.
+.TP
+\f[B]ASCIINEMA_CONFIG_HOME\f[R]
+This variable allows overriding config directory location.
+Default location is $XDG_CONFIG_HOME/asciinema (when $XDG_CONFIG_HOME is
+set) or $HOME/.config/asciinema.

+NAME
+====
+
+**asciinema** - terminal session recorder
+
+
+SYNOPSIS
+========
+
+| **asciinema \-\-version**
+| **asciinema** _command_ \[_options_] \[_args_]
+
+
+DESCRIPTION
+===========
+
+asciinema lets you easily record terminal sessions, replay
+them in a terminal as well as in a web browser and share them on the web.
+asciinema is Free and Open Source Software licensed under
+the GNU General Public License v3.
+
+
+COMMANDS
+========
+
+asciinema is composed of multiple commands, similar to `git`, `apt-get` or
+`brew`.
+
+When you run **asciinema** with no arguments a help message is displayed, listing
+all available commands with their options.
+
+
+rec [_filename_]
+---
+
+Record terminal session.
+
+By running **asciinema rec [filename]** you start a new recording session. The
+command (process) that is recorded can be specified with **-c** option (see
+below), and defaults to **$SHELL** which is what you want in most cases.
+
+You can temporarily pause the capture of your terminal by pressing
+<kbd>Ctrl+\\</kbd>.  This is useful when you want to execute some commands during
+the recording session that should not be captured (e.g. pasting secrets). Resume
+by pressing <kbd>Ctrl+\\</kbd> again. When pausing desktop notification is
+displayed so you're sure the sensitive output won't be captured in the
+recording.
+
+Recording finishes when you exit the shell (hit <kbd>Ctrl+D</kbd> or type
+`exit`). If the recorded process is not a shell then recording finishes when
+the process exits.
+
+If the _filename_ argument is omitted then (after asking for confirmation) the
+resulting asciicast is uploaded to
+[asciinema-server](https://github.com/asciinema/asciinema-server) (by default to
+asciinema.org), where it can be watched and shared.
+
+If the _filename_ argument is given then the resulting recording (called
+[asciicast](doc/asciicast-v2.md)) is saved to a local file. It can later be
+replayed with **asciinema play \<filename>** and/or uploaded to asciinema server
+with **asciinema upload \<filename>**.
+
+**ASCIINEMA_REC=1** is added to recorded process environment variables. This
+can be used by your shell's config file (`.bashrc`, `.zshrc`) to alter the
+prompt or play a sound when the shell is being recorded.
+
+Available options:
+
+:   &nbsp;
+
+    `--stdin`
+    :   Enable stdin (keyboard) recording (see below)
+
+    `--append`
+    :   Append to existing recording
+
+    `--raw`
+    :   Save raw STDOUT output, without timing information or other metadata
+
+    `--overwrite`
+    :   Overwrite the recording if it already exists
+
+    `-c, --command=<command>`
+    :   Specify command to record, defaults to **$SHELL**
+
+    `-e, --env=<var-names>`
+    :   List of environment variables to capture, defaults to **SHELL,TERM**
+
+    `-t, --title=<title>`
+    :   Specify the title of the asciicast
+
+    `-i, --idle-time-limit=<sec>`
+    :   Limit recorded terminal inactivity to max `<sec>` seconds
+
+    `--cols=<n>`
+    :   Override terminal columns for recorded process
+
+    `--rows=<n>`
+    :   Override terminal rows for recorded process
+
+    `-y, --yes`
+    :   Answer "yes" to all prompts (e.g. upload confirmation)
+
+    `-q, --quiet`
+    :   Be quiet, suppress all notices/warnings (implies **-y**)
+
+Stdin recording allows for capturing of all characters typed in by the user in
+the currently recorded shell. This may be used by a player (e.g.
+[asciinema-player](https://github.com/asciinema/asciinema-player)) to display
+pressed keys. Because it's basically a key-logging (scoped to a single shell
+instance), it's disabled by default, and has to be explicitly enabled via
+**--stdin** option.
+
+
+play <_filename_>
+---
+
+Replay recorded asciicast in a terminal.
+
+This command replays a given asciicast (as recorded by **rec** command) directly in
+your terminal. The asciicast can be read from a file or from *`stdin`* ('-'):
+
+Playing from a local file:
+
+    asciinema play /path/to/asciicast.cast
+
+Playing from HTTP(S) URL:
+
+    asciinema play https://asciinema.org/a/22124.cast
+    asciinema play http://example.com/demo.cast
+
+Playing from asciicast page URL (requires `<link rel="alternate"
+type="application/x-asciicast" href="/my/ascii.cast">` in page's HTML):
+
+    asciinema play https://asciinema.org/a/22124
+    asciinema play http://example.com/blog/post.html
+
+Playing from stdin:
+
+    cat /path/to/asciicast.cast | asciinema play -
+    ssh user@host cat asciicast.cast | asciinema play -
+
+Playing from IPFS:
+
+    asciinema play dweb:/ipfs/QmNe7FsYaHc9SaDEAEXbaagAzNw9cH7YbzN4xV7jV1MCzK/ascii.cast
+
+Available options:
+
+:   &nbsp;
+
+    `-i, --idle-time-limit=<sec>`
+    : Limit replayed terminal inactivity to max `<sec>` seconds (can be fractional)
+
+    `-s, --speed=<factor>`
+    : Playback speed (can be fractional)
+
+While playing the following keyboard shortcuts are available:
+
+:    &nbsp;
+
+    *`Space`*
+    :   Toggle pause
+
+    *`.`*
+    :   Step through a recording a frame at a time (when paused)
+
+    *`Ctrl+C`*
+    :   Exit
+
+Recommendation: run 'asciinema play' in a terminal of dimensions not smaller than the one
+used for recording as there's no "transcoding" of control sequences for the new terminal
+size.
+
+
+cat <_filename_>
+---
+
+Print full output of recorded asciicast to a terminal.
+
+While **asciinema play <filename>** replays the recorded session using timing
+information saved in the asciicast, **asciinema cat <filename>** dumps the full
+output (including all escape sequences) to a terminal immediately.
+
+**asciinema cat existing.cast >output.txt** gives the same result as recording via
+**asciinema rec \-\-raw output.txt**.
+
+
+upload <_filename_>
+------
+
+Upload recorded asciicast to asciinema.org site.
+
+This command uploads given asciicast (recorded by **rec** command) to
+asciinema.org, where it can be watched and shared.
+
+**asciinema rec demo.cast** + **asciinema play demo.cast** + **asciinema upload
+demo.cast** is a nice combo if you want to review an asciicast before
+publishing it on asciinema.org.
+
+auth
+----
+
+Link and manage your install ID with your asciinema.org user account.
+
+If you want to manage your recordings (change title/theme, delete) at
+asciinema.org you need to link your "install ID" with your asciinema.org user
+account.
+
+This command displays the URL to open in a web browser to do that. You may be
+asked to log in first.
+
+Install ID is a random ID ([UUID
+v4](https://en.wikipedia.org/wiki/Universally_unique_identifier)) generated
+locally when you run asciinema for the first time, and saved at
+**$HOME/.config/asciinema/install-id**. It's purpose is to connect local machine
+with uploaded recordings, so they can later be associated with asciinema.org
+account. This way we decouple uploading from account creation, allowing them to
+happen in any order.
+
+Note: A new install ID is generated on each machine and system user account you use
+asciinema on. So in order to keep all recordings under a single asciinema.org
+account you need to run **asciinema auth** on all of those machines. If you’re
+already logged in on asciinema.org website and you run 'asciinema auth' from a new
+computer then this new device will be linked to your account.
+
+While you CAN synchronize your config file (which keeps the API token) across
+all your machines so all use the same token, that’s not necessary. You can assign
+new tokens to your account from as many machines as you want.
+
+Note: asciinema versions prior to 2.0 confusingly referred to install ID as "API
+token".
+
+
+EXAMPLES
+========
+
+Record your first session:
+
+    asciinema rec first.cast
+
+End your session:
+
+    exit
+
+Now replay it with double speed:
+
+    asciinema play -s 2 first.cast
+
+Or with normal speed but with idle time limited to 2 seconds:
+
+    asciinema play -i 2 first.cast
+
+You can pass **-i 2** to **asciinema rec** as well, to set it permanently on a
+recording. Idle time limiting makes the recordings much more interesting to
+watch, try it.
+
+If you want to watch and share it on the web, upload it:
+
+    asciinema upload first.cast
+
+The above uploads it to <https://asciinema.org>, which is a
+default asciinema-server (<https://github.com/asciinema/asciinema-server>)
+instance, and prints a secret link you can use to watch your recording in a web
+browser.
+
+You can record and upload in one step by omitting the filename:
+
+    asciinema rec
+
+You'll be asked to confirm the upload when the recording is done, so nothing is
+sent anywhere without your consent.
+
+
+Tricks
+------
+
+Record slowly, play faster:
+
+:   First record a session where you can take your time to type slowly what you want
+    to show in the recording:
+
+        asciinema rec initial.cast
+
+    Then record the replay of 'initial.cast' as 'final.cast', but with five times the
+    initially recorded speed, with all pauses capped to two seconds and with a title
+    set as "My fancy title"::
+
+        asciinema rec -c "asciinema play -s 5 -i 2 initial.cast" -t "My fancy title" final.cast
+
+Play from *`stdin`*:
+
+:   &nbsp;
+
+    cat /path/to/asciicast.json | asciinema play -
+
+Play file from remote host accessible with SSH:
+
+:   &nbsp;
+
+    ssh user@host cat /path/to/asciicat.json | asciinema play -
+
+
+ENVIRONMENT
+===========
+
+**ASCIINEMA_API_URL**
+
+:   This variable allows overriding asciinema-server URL (which defaults to
+    https://asciinema.org) in case you're running your own asciinema-server instance.
+
+**ASCIINEMA_CONFIG_HOME**
+
+:   This variable allows overriding config directory location. Default location
+    is $XDG\_CONFIG\_HOME/asciinema (when $XDG\_CONFIG\_HOME is set)
+    or $HOME/.config/asciinema.
