+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *

+*  (not any Contributor) assume the cost of any necessary servicing,   *

+*  including, without limitation, damages for lost profits, loss of    *

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or

+distinguishing version number.
+
+10.2. Effect of New Versions

+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,

+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a

+# 💄📝 Les·M·L
+
+<b>Ladys simple markup language.</b>
+
+💄📝 Les·M·L is a document markup language designed with two goals in
+  mind :⁠—
+
+1. It must be trivial to parse, even with limited tooling such as that
+     provided by X·S·L·T.
+
+2. It must be sophisticated enough to handle longform hypertext
+     documents and associated metadata.
+
+It is implemented as an X·S·L·T transformation from a
+  `<html:script type="text/lesml">` element into H·T·M·L
+  (`parser.xslt`).
+
+## Nomenclature
+
+<i>Les·M·L</i> is an abbreviation of the phrase “Ladys Extremely Simple
+  Markup Language”.
+
+## Markup Syntax
+
+The first line of any 💄📝 Les·M·L document should be the string
+  `#!lesml`.
+
+Following the shebang, document metadata may be provided in the [Record
+  Jar][draft-phillips-record-jar-01] format.
+The body of the document begins after the last line which begins with
+  the string `%%`, or after the shebang line if none exists.
+
+Documents are broken into paragraphs by blank lines.
+Non·empty paragraphs are classified as follows :⁠—
+
+- If the paragraph consists of only the characters
+    `#*-=_~⁂─━┄┅┈┉╌╍═╴╶╸╺☙❧` plus any amount of white·space, then it is
+    considered to be a section break (`<html:hr>`).
+
+- If every line in the paragraph begins with at least one space, then
+    it is considered to be a quoted paragraph (`<html:blockquote>`).
+  There is only one level of paragraph quoting; quoted paragraphs may
+    not be quoted again.
+
+- Otherwise, the paragraph is unquoted.
+
+After this classification, each quoted or unquoted paragraph is further
+  classified by type based on its first character (which is must be
+   followed by white·space to be recognized) :⁠—
+
+- If the paragraph begins with `⁌`, it is a chapter heading
+    (`<html:h1>`).
+
+- If the paragraph begins with `§`, it is a section heading
+    (`<html:h2>`).
+
+- If the paragraph begins with `✠`, it is a subsection heading
+    (`<html:h3>`).
+
+- If the paragraph begins with `❦`, it is a subsubsection heading
+    (`<html:h4>`).
+
+- If the paragraph begins with `•` or `🔢`, it is a primary unordered
+    or ordered list item (`<html:li class="unordered" data-level="1">`
+    or `<html:li class="ordered" data-level="1">`).
+
+- If the paragraph begins with `◦` or `🔠`, it is a secondary unordered
+    or ordered list item (`<html:li class="unordered" data-level="2">`
+    or `<html:li class="ordered" data-level="2">`).
+  Secondary list items are considered to be nested inside of primary
+    list items which precede them.
+
+- If the paragraph begins with `‣` or `🔡`, it is a tertiary unordered
+    or ordered list item (`<html:li class="unordered" data-level="3">`
+    or `<html:li class="ordered" data-level="3">`).
+  Tertiary list items are considered to be nested inside of primary
+    and secondary list items which precede them.
+
+- If the paragraph begins with `⁃` or `🔣`, it is a quaternary
+    unordered or ordered list item
+    (`<html:li class="unordered" data-level="4">` or
+    `<html:li class="ordered" data-level="4">`).
+  Quaternary list items are considered to be nested inside of primary,
+    secondary, and tertiary list items which precede them.
+
+- If the paragraph begins with `※`, it is an ordinary note
+    (`<html:div role="note" class="note">`).
+
+- If the paragraph begins with `☡`, it is a cautionary note
+    (`<html:div role="note" class="caution">`).
+
+- If the paragraph begins with `🛈`, it is an informative note
+    (`<html:div role="note" class="info">`).
+
+- If the paragraph begins with `⯑`, it is a questioning note
+    (`<html:div role="note" class="query">`).
+
+- If the paragraph begins with `⚠︎`, it is a warning note
+    (`<html:div role="note" class="warn">`).
+
+- If the paragraph begins with `⋯`, it is a continuation paragraph
+    (`<html:div class="continuation">`).
+  Continuation paragraphs may be used to continue a preceding list item
+    or quote.
+  Note, however, that an unquoted paragraph cannot continue a quoted
+    one, or vice·versa.
+
+- Otherwise, it is an ordinary paragraph.
+
+Following this sigil (if any, including trailing white·space) there may
+  be a `¶` followed by zero or more non·white·space characters.
+The characters following the `¶` give the identifier for the paragraph,
+  which is expected to be unique within a document.
+
+The remaining characters in a paragraph form its contents.
+Markup within paragraphs is delimited with·out exception by pairs of
+  characters, with the following precedence :⁠—
+
+- The characters `{🔗` and `>}` indicate a hyperlink to a U·R·L
+    (`<html:a>`).
+  The hyperlink must contain at least one `<`; the content before the
+    last `<` gives the text of the link, and the content after gives
+    the U·R·L that the link points to.
+  If no text is given, the U·R·L will be used instead.
+
+- The characters `⸠` and `⸡` indicate a strikethru (`<html:s>`).
+
+- The characters `⸤` and `⸥` indicate underlining (`<html:u>`).
+
+- The characters `⟦` and `⟧` indicate an inline note
+    (`<html:small role="note">`).
+
+- The characters `⸨` and `⸩` indicate parenthetical content
+    (`<html:small>`).
+
+- The characters `☞︎` and `☜︎` indicate strong importance
+    (`<html:strong>`).
+
+- The characters `⹐` and `⹑` indicate emphasis (`<html:em>`).
+
+- The characters `⟪` and `⟫` indicate titles (`<html:cite>`).
+
+- The characters `⟨` and `⟩` indicate offset text (`<html:i>`).
+  This may be followed by a `@`, a language tag, and a `$` to provide
+    the language of the text.
+
+- The characters `⦃` and `⦄` indicate keyword highlighting
+    (`<html:b>`).
+
+- The characters `` ` `` and `´` indicate code (`<html:code>`).
+
+Once the tree is built as above, it is remediated into its final form
+  by the following steps :⁠—
+
+- Successive quoted paragraphs are joined into one quote.
+  If the final quoted paragraph is an ordinary paragraph which begins
+    with `—` and a space, the quote is wrapped in a `<html:figure>`
+    and the final paragraph becomes its `<html:figcaption>`.
+
+- Continuation paragraphs are joined with the preceding list items or
+    quotes.
+
+- List items of a higher level are nested in preceding list items, when
+    present.
+
+- Successive list items of the same level and class are joined into
+    a single list.
+
+Finally, any character can be escaped by instead providing its Unicode
+  codepoint in the form `<U+NNNN>`, where `NNNN` is one or more
+  hexadecimal digits.
+Multiple codepoints may be provided separated by periods, as in
+  `<U+WWWW.ZZZZ>`
