+   The following calling convention macros are defined for frequently
+   called functions:
+
+   FASTCALL    - Used for those internal functions that have a simple
+                 body and a low number of arguments and local variables.
+
+   PTRCALL     - Used for functions called though function pointers.
+
+   PTRFASTCALL - Like PTRCALL, but for low number of arguments.
+
+   inline      - Used for selected internal functions for which inlining
+                 may improve performance on some platforms.
+
+   Note: Use of these macros is based on judgement, not hard rules,
+         and therefore subject to change.

+ * siphash.h - SipHash-2-4 in a single header file
+ * --------------------------------------------------------------------------
+ * Derived by William Ahern from the reference implementation[1] published[2]
+ * by Jean-Philippe Aumasson and Daniel J. Berstein. Licensed in kind.
+ * by Jean-Philippe Aumasson and Daniel J. Berstein.
+ * Minimal changes by Sebastian Pipping on top, details below.
+ * Licensed under the CC0 Public Domain Dedication license.
+ *
+ * 1. https://www.131002.net/siphash/siphash24.c
+ * 2. https://www.131002.net/siphash/
+ * --------------------------------------------------------------------------
+ * HISTORY:
+ *
+ * 2017-06-10  (Sebastian Pipping)
+ *   - Clarify license note in the header
+ *   - Address C89 issues:
+ *     - Stop using inline keyword (and let compiler decide)
+ *     - Turn integer suffix ULL to UL
+ *     - Replace _Bool by int
+ *     - Turn macro siphash24 into a function
+ *     - Address invalid conversion (void pointer) by explicit cast
+ *   - Always expose sip24_valid (for self-tests)
+ *
+ * 2012-11-04 - Born.  (William Ahern)
+ * --------------------------------------------------------------------------
+ * USAGE:
+ *
+ * SipHash-2-4 takes as input two 64-bit words as the key, some number of
+ * message bytes, and outputs a 64-bit word as the message digest. This
+ * implementation employs two data structures: a struct sipkey for
+ * representing the key, and a struct siphash for representing the hash
+ * state.
+ *
+ * For converting a 16-byte unsigned char array to a key, use either the
+ * macro sip_keyof or the routine sip_tokey. The former instantiates a
+ * compound literal key, while the latter requires a key object as a
+ * parameter.
+ *
+ * 	unsigned char secret[16];
+ * 	arc4random_buf(secret, sizeof secret);
+ * 	struct sipkey *key = sip_keyof(secret);
+ *
+ * For hashing a message, use either the convenience macro siphash24 or the
+ * routines sip24_init, sip24_update, and sip24_final.
+ *
+ * 	struct siphash state;
+ * 	void *msg;
+ * 	size_t len;
+ * 	uint64_t hash;
+ *
+ * 	sip24_init(&state, key);
+ * 	sip24_update(&state, msg, len);
+ * 	hash = sip24_final(&state);
+ *
+ * or
+ *
+ * 	hash = siphash24(msg, len, key);
+ *
+ * To convert the 64-bit hash value to a canonical 8-byte little-endian
+ * binary representation, use either the macro sip_binof or the routine
+ * sip_tobin. The former instantiates and returns a compound literal array,
+ * while the latter requires an array object as a parameter.
+ * --------------------------------------------------------------------------
+ * NOTES:
+ *
+ * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
+ *   lacking compound literal support. Instead, you must use the lower-level
+ *   interfaces which take as parameters the temporary state objects.
+ *
+ * o Uppercase macros may evaluate parameters more than once. Lowercase
+ *   macros should not exhibit any such side effects.

+If this is your first time building the HTML5 parser, you need to execute the
+following commands (from this directory) to bootstrap the translation:
+
+  make sync             # fetch remote source files and licenses
+  make translate        # perform the Java-to-C++ translation from the remote
+                        # sources
+  make named_characters # Generate tables for named character tokenization
+
+If you make changes to the translator or the javaparser, you can rebuild by
+retyping 'make' in this directory.  If you make changes to the HTML5 Java
+implementation, you can retranslate the Java sources from the htmlparser
+repository by retyping 'make translate' in this directory.
+
+The makefile supports the following targets:
+
+sync_htmlparser:
+  Retrieves the HTML parser and Java to C++ translator sources from GitHub.
+sync_javaparser:
+  Retrieves the javaparser sources from GitHub.
+sync:
+  Runs both sync_javaparser and sync_htmlparser.
+javaparser:
+  Builds the javaparser library retrieved earlier by sync_javaparser.
+translator:
+  Runs the javaparser target and then builds the Java to C++ translator from
+  sources retrieved earlier by sync_htmlparser.
+libs:
+  The default target. Alias for translator
+translate:
+  Runs the translator target and then translates the HTML parser sources
+  retrieved by sync_htmlparser copying the Java sources to ../javasrc.
+translate_from_snapshot:
+  Runs the translator target and then translates the HTML parser sources
+  stored in ../javasrc.
+named_characters:
+  Generates data tables for named character tokenization.

+         *
+         * Switching to another state
+         *
+         * To switch to another state, the code sets the state variable to the
+         * magic number of the new state. Then it either continues stateloop or
+         * breaks out of the state's own wrapper loop if the target state is
+         * right after the current state in source order. (This is a partial

+         * Reconsume support
+         *
+         * The spec sometimes says that an input character is reconsumed in
+         * another state. If a state can ever be entered so that an input
+         * character can be reconsumed in it, the state's code starts with an
+         * |if (reconsume)| that sets reconsume to false and skips over the
+         * normal code for consuming a new character.
+         *
+         * To reconsume the current character in another state, the code sets
+         * |reconsume| to true and then switches to the other state.
+         *
+         *
+         * Emitting character tokens
+         *
+         * This method emits character tokens lazily. Whenever a new range of
+         * character tokens starts, the field cstart must be set to the start
+         * index of the range. The flushChars() method must be called at the end
+         * of a range to flush it.
+         *
+         *
+         * U+0000 handling
+         *
+         * The various states have to handle the replacement of U+0000 with
+         * U+FFFD. However, if U+0000 would be reconsumed in another state, the
+         * replacement doesn't need to happen, because it's handled by the
+         * reconsuming state.
+         *
+         *
+         * LF handling
+         *
+         * Every state needs to increment the line number upon LF unless the LF
+         * gets reconsumed by another state which increments the line number.
+         *
+         *
+         * CR handling
+         *
+         * Every state needs to handle CR unless the CR gets reconsumed and is
+         * handled by the reconsuming state. The CR needs to be handled as if it
+         * were and LF, the lastCR field must be set to true and then this

+/**
+ * nsHtml5AtomTable provides non-locking lookup and creation of atoms for
+ * nsHtml5Parser or nsHtml5StreamParser.
+ *
+ * The hashtable holds dynamically allocated atoms that are private to an
+ * instance of nsHtml5Parser or nsHtml5StreamParser. (Static atoms are used on
+ * interned nsHtml5ElementNames and interned nsHtml5AttributeNames. Also, when
+ * the doctype name is 'html', that identifier needs to be represented as a
+ * static atom.)
+ *
+ * Each instance of nsHtml5Parser has a single instance of nsHtml5AtomTable,
+ * and each instance of nsHtml5StreamParser has a single instance of
+ * nsHtml5AtomTable. Dynamic atoms obtained from an nsHtml5AtomTable are valid
+ * for == comparison with each other or with atoms declared in nsHtml5Atoms
+ * within the nsHtml5Tokenizer and the nsHtml5TreeBuilder instances owned by
+ * the same nsHtml5Parser/nsHtml5StreamParser instance that owns the
+ * nsHtml5AtomTable instance.
+ *
+ * Dynamic atoms (atoms whose IsStatic() returns false) obtained from
+ * nsHtml5AtomTable must be re-obtained from another atom table when there's a
+ * need to migrate atoms from an nsHtml5Parser to its nsHtml5StreamParser
+ * (re-obtain from the other nsHtml5AtomTable), from an nsHtml5Parser to its
+ * owner nsHtml5Parser (re-obtain from the other nsHtml5AtomTable) or from the
+ * parser to the DOM (re-obtain from the application-wide atom table). To
+ * re-obtain an atom from another atom table, obtain a string from the atom
+ * using ToString(nsAString&) and look up an atom in the other table using that
+ * string.
+ *
+ * An instance of nsHtml5AtomTable that belongs to an nsHtml5Parser is only
+ * accessed from the main thread. An instance of nsHtml5AtomTable that belongs
+ * to an nsHtml5StreamParser is accessed both from the main thread and from the
+ * thread that executes the runnables of the nsHtml5StreamParser instance.
+ * However, the threads never access the nsHtml5AtomTable instance concurrently
+ * in the nsHtml5StreamParser case.
+ *
+ * Methods on the atoms obtained from nsHtml5AtomTable may be called on any
+ * thread, although they only need to be called on the main thread or on the
+ * thread working for the nsHtml5StreamParser when nsHtml5AtomTable belongs to
+ * an nsHtml5StreamParser.
+ *
+ * Dynamic atoms obtained from nsHtml5AtomTable are deleted when the
+ * nsHtml5AtomTable itself is destructed, which happens when the owner
+ * nsHtml5Parser or nsHtml5StreamParser is destructed.

+ * Note that nsHtml5StreamParser implements cycle collecting AddRef and
+ * Release. Therefore, nsHtml5StreamParser must never be refcounted from
+ * the parser thread!
+ *
+ * To work around this limitation, runnables posted by the main thread to the
+ * parser thread hold their reference to the stream parser in an
+ * nsHtml5StreamParserPtr. Upon creation, nsHtml5StreamParserPtr addrefs the
+ * object it holds
+ * just like a regular nsRefPtr. This is OK, since the creation of the
+ * runnable and the nsHtml5StreamParserPtr happens on the main thread.
+ *
+ * When the runnable is done on the parser thread, the destructor of
+ * nsHtml5StreamParserPtr runs there. It doesn't call Release on the held object
+ * directly. Instead, it posts another runnable back to the main thread where
+ * that runnable calls Release on the wrapped object.
+ *
+ * When posting runnables in the other direction, the runnables have to be
+ * created on the main thread when nsHtml5StreamParser is instantiated and
+ * held for the lifetime of the nsHtml5StreamParser. This works, because the
+ * same runnabled can be dispatched multiple times and currently runnables
+ * posted from the parser thread to main thread don't need to wrap any
+ * runnable-specific data. (In the other direction, the runnables most notably
+ * wrap the byte data of the stream.)

+/*
+ * The general idea is to match WebKit and Blink exactly for meta
+ * scan except:
+ *
+ * 1. WebKit and Blink look for meta as if scripting was disabled
+ *    for `noscript` purposes. This implementation matches the
+ *    `noscript` treatment of the observable DOM building (in order
+ *    to be able to use the same tree builder run).
+ * 2. WebKit and Blink look for meta as if the foreign content
+ *    feedback from the tree builder to the tokenizer didn't exist.
+ *    This implementation considers the foreign content rules in
+ *    order to be able to use the same tree builder run for meta
+ *    and the observable DOM building. Note that since <svg> and
+ *    <math> imply the end of head, this only matters for meta after
+ *    head but starting within the 1024-byte zone.
+ *
+ * Template is treated specially, because that WebKit/Blink behavior
+ * is easy to emulate unlike the above two exceptions. In general,
+ * the meta scan token handler in WebKit and Blink behaves as if there
+ * was a scripting-disabled tree builder predating the introduction
+ * of foreign content and template.
+ *
+ * Meta is honored if it _starts_ within the first 1024 kilobytes or,
+ * if by the 1024-byte boundary head hasn't ended and a template
+ * element hasn't started, a meta occurs before the first of the head
+ * ending or a template element starting.
+ *
+ * If a meta isn't honored according to the above definition, and
+ * we aren't dealing with plain text, the buffered bytes, which by
+ * now have to contain `>` character unless we encountered EOF, are
+ * scanned for syntax resembling an XML declaration.
+ *
+ * If neither a meta nor syntax resembling an XML declaration has
+ * been honored and we aren't inheriting the encoding from a
+ * same-origin parent or parsing for XHR, chardetng is used.
+ * chardetng runs first for the part of the document that was searched
+ * for meta and then at EOF. The part searched for meta is defined as
+ * follows in order to avoid network buffer boundary-dependent
+ * behavior:
+ *
+ * 1. At least the first 1024 bytes. (This is what happens for plain
+ *    text.)
+ * 2. If the 1024-byte boundary is within a tag, comment, doctype,
+ *    or CDATA section, at least up to the end of that token or CDATA
+ *    section. (Exception: If the 1024-byte boundary is in an RCDATA
+ *    end tag that hasn't yet been decided to be an end tag, the
+ *    token is not considered.)
+ * 3. If at the 1024-byte boundary, head hasn't ended and there hasn't
+ *    been a template tag, up to the end of the first template tag
+ *    or token ending the head, whichever comes first.
+ * 4. Except if head is ended by a text token, only to the end of the
+ *    most recent tag, comment, or doctype token. (Because text is
+ *    coalesced, so it would be harder to correlate the text to the
+ *    bytes.)
+ *
+ * An encoding-related reload is still possible if chardetng's guess
+ * at EOF differs from its initial guess.

+  It is designed to be used as input to various places that will define the

+
+  It is recommended (but not strictly necessary) to keep all entries
+  in alphabetical order.

+  The first argument to HTML_TAG is the tag name. The second argument is the
+  "creator" method of the form NS_New$TAGNAMEElement, that will be used by
+  nsHTMLContentSink.cpp to create a content object for a tag of that
+  type. Use NOTUSED, if the particular tag has a non-standard creator.
+  The third argument is the interface name specified for this element
+  in the HTML specification. It can be empty if the relevant interface name
+  is "HTMLElement".
+
+  The HTML_OTHER macro is for values in the nsHTMLTag enum that are
+  not strictly tags.
+
+  Entries *must* use only lowercase characters.
+
+  Don't forget to update /editor/libeditor/HTMLEditUtils.cpp as well.

+ * Do NOT implement!
+ *
+ * This file declares the concrete HTMLContentSink class.
+ * This class is used during the parsing process as the
+ * primary interface between the parser and the content
+ * model.
+ *
+ * After the tokenizer completes, the parser iterates over
+ * the known token list. As the parser identifies valid
+ * elements, it calls the contentsink interface to notify
+ * the content model that a new node or child node is being
+ * created and added to the content model.
+ *
+ * The HTMLContentSink interface assumes 4 underlying
+ * containers: HTML, HEAD, BODY and FRAMESET. Before
+ * accessing any these, the parser will call the appropriate
+ * OpennsIHTMLContentSink method: OpenHTML,OpenHead,OpenBody,OpenFrameSet;
+ * likewise, the ClosensIHTMLContentSink version will be called when the
+ * parser is done with a given section.
+ *
+ * IMPORTANT: The parser may Open each container more than
+ * once! This is due to the irregular nature of HTML files.
+ * For example, it is possible to encounter plain text at
+ * the start of an HTML document (that precedes the HTML tag).
+ * Such text is treated as if it were part of the body.
+ * In such cases, the parser will Open the body, pass the text-
+ * node in and then Close the body. The body will likely be
+ * re-Opened later when the actual <BODY> tag has been seen.
+ *
+ * Containers within the body are Opened and Closed
+ * using the OpenContainer(...) and CloseContainer(...) calls.
+ * It is assumed that the document or contentSink is
+ * maintaining its state to manage where new content should
+ * be added to the underlying document.
+ *
+ * NOTE: OpenHTML() and OpenBody() may get called multiple times
+ *       in the same document. That's fine, and it doesn't mean
+ *       that we have multiple bodies or HTML's.
+ *
+ * NOTE: I haven't figured out how sub-documents (non-frames)

+//-------------- Begin ParseContinue Event Definition ------------------------
+/*
+The parser can be explicitly interrupted by passing a return value of
+NS_ERROR_HTMLPARSER_INTERRUPTED from BuildModel on the DTD. This will cause
+the parser to stop processing and allow the application to return to the event
+loop. The data which was left at the time of interruption will be processed
+the next time OnDataAvailable is called. If the parser has received its final
+chunk of data then OnDataAvailable will no longer be called by the networking
+module, so the parser will schedule a nsParserContinueEvent which will call
+the parser to process the remaining data after returning to the event loop.
+If the parser is interrupted while processing the remaining data it will
+schedule another ParseContinueEvent. The processing of data followed by
+scheduling of the continue events will proceed until either:
+
+  1) All of the remaining data can be processed without interrupting
+  2) The parser has been cancelled.
+
+
+This capability is currently used in CNavDTD and nsHTMLContentSink. The
+nsHTMLContentSink is notified by CNavDTD when a chunk of tokens is going to be
+processed and when each token is processed. The nsHTML content sink records
+the time when the chunk has started processing and will return
+NS_ERROR_HTMLPARSER_INTERRUPTED if the token processing time has exceeded a
+threshold called max tokenizing processing time. This allows the content sink
+to limit how much data is processed in a single chunk which in turn gates how
+much time is spent away from the event loop. Processing smaller chunks of data
+also reduces the time spent in subsequent reflows.
+
+This capability is most apparent when loading large documents. If the maximum
+token processing time is set small enough the application will remain
+responsive during document load.
+
+A side-effect of this capability is that document load is not complete when
+the last chunk of data is passed to OnDataAvailable since  the parser may have
+been interrupted when the last chunk of data arrived. The document is complete
+when all of the document has been tokenized and there aren't any pending
+nsParserContinueEvents. This can cause problems if the application assumes
+that it can monitor the load requests to determine when the document load has
+been completed. This is what happens in Mozilla. The document is considered
+completely loaded when all of the load requests have been satisfied. To delay
+the document load until all of the parsing has been completed the
+nsHTMLContentSink adds a dummy parser load request which is not removed until
+the nsHTMLContentSink's DidBuildModel is called. The CNavDTD will not call
+DidBuildModel until the final chunk of data has been passed to the parser
+through the OnDataAvailable and there aren't any pending
+nsParserContineEvents.
+
+Currently the parser is ignores requests to be interrupted during the
+processing of script.  This is because a document.write followed by JavaScript
+calls to manipulate the DOM may fail if the parser was interrupted during the
+document.write.

+ *  This routine is called to cause the parser to continue parsing its

+ *  chunks, such as when the content is push based, and we need to parse in
+ *  pieces.
+ *
+ *  An interesting change in how the parser gets used has led us to add extra
+ *  processing to this method.  The case occurs when the parser is blocked in
+ *  one context, and gets a parse(string) call in another context.  In this
+ *  case, the parserContexts are linked. No problem.
+ *
+ *  The problem is that Parse(string) assumes that it can proceed unabated,
+ *  but if the parser is already blocked that assumption is false. So we
+ *  needed to add a mechanism here to allow the parser to continue to process
+ *  (the pop and free) contexts until 1) it get's blocked again; 2) it runs
+ *  out of contexts.
+ *
+ *

+/**
+ * MODULE NOTES:
+ *
+ *  This class does two primary jobs:
+ *    1) It iterates the tokens provided during the
+ *       tokenization process, identifing where elements
+ *       begin and end (doing validation and normalization).
+ *    2) It controls and coordinates with an instance of
+ *       the IContentSink interface, to coordinate the
+ *       the production of the content model.
+ *
+ *  The basic operation of this class assumes that an HTML
+ *  document is non-normalized. Therefore, we don't process
+ *  the document in a normalized way. Don't bother to look
+ *  for methods like: doHead() or doBody().
+ *
+ *  Instead, in order to be backward compatible, we must
+ *  scan the set of tokens and perform this basic set of
+ *  operations:
+ *    1)  Determine the token type (easy, since the tokens know)
+ *    2)  Determine the appropriate section of the HTML document
+ *        each token belongs in (HTML,HEAD,BODY,FRAMESET).
+ *    3)  Insert content into our document (via the sink) into
+ *        the correct section.
+ *    4)  In the case of tags that belong in the BODY, we must
+ *        ensure that our underlying document state reflects
+ *        the appropriate context for our tag.
+ *
+ *        For example,if we see a <TR>, we must ensure our
+ *        document contains a table into which the row can
+ *        be placed. This may result in "implicit containers"
+ *        created to ensure a well-formed document.

+ *
+ * The buffer list itself is reference counted.  This allows the buffer list
+ * to be shared by multiple nsScannerSubstring objects.  The reference
+ * counting is not threadsafe, which is not at all a requirement.
+ *
+ * When a nsScannerSubstring releases its reference to a buffer list, it
+ * decrements the usage count of the first buffer in the buffer list that it
+ * was referencing.  It informs the buffer list that it can discard buffers
+ * starting at that prefix.  The buffer list will do so if the usage count of
+ * that buffer is 0 and if it is the first buffer in the list.  It will
+ * continue to prune buffers starting from the front of the buffer list until
+ * it finds a buffer that has a usage count that is non-zero.

+Tree Construction Tests
+=======================
+
+Each file containing tree construction tests consists of any number of
+tests separated by two newlines (LF) and a single newline before the end
+of the file. For instance:
+
+    [TEST]LF
+    LF
+    [TEST]LF
+    LF
+    [TEST]LF
+
+Where [TEST] is the following format:
+
+Each test must begin with a string "\#data" followed by a newline (LF).
+All subsequent lines until a line that says "\#errors" are the test data
+and must be passed to the system being tested unchanged, except with the
+final newline (on the last line) removed.
+
+Then there must be a line that says "\#errors". It must be followed by
+one line per parse error that a conformant checker would return. It
+doesn't matter what those lines are, although they can't be
+"\#document-fragment", "\#document", "\#script-off", "\#script-on", or
+empty, the only thing that matters is that there be the right number
+of parse errors.
+
+Then there \*may\* be a line that says "\#document-fragment", which must
+be followed by a newline (LF), followed by a string of characters that
+indicates the context element, followed by a newline (LF). If the string 
+of characters starts with "svg ", the context element is in the SVG
+namespace and the substring after "svg " is the local name. If the
+string of characters starts with "math ", the context element is in the
+MathML namespace and the substring after "math " is the local name.
+Otherwise, the context element is in the HTML namespace and the string
+is the local name. If this line is present the "\#data" must be parsed
+using the HTML fragment parsing algorithm with the context element as
+context.
+
+Then there \*may\* be a line that says "\#script-off" or
+"\#script-in". If a line that says "\#script-off" is present, the
+parser must set the scripting flag to disabled. If a line that says
+"\#script-on" is present, it must set it to enabled. Otherwise, the
+test should be run in both modes.
+
+Then there must be a line that says "\#document", which must be followed
+by a dump of the tree of the parsed DOM. Each node must be represented
+by a single line. Each line must start with "| ", followed by two spaces
+per parent node that the node has before the root document node.
+
+-   Element nodes must be represented by a "`<`" then the *tag name
+    string* "`>`", and all the attributes must be given, sorted
+    lexicographically by UTF-16 code unit according to their *attribute
+    name string*, on subsequent lines, as if they were children of the
+    element node.
+-   Attribute nodes must have the *attribute name string*, then an "="
+    sign, then the attribute value in double quotes (").
+-   Text nodes must be the string, in double quotes. Newlines aren't
+    escaped.
+-   Comments must be "`<`" then "`!-- `" then the data then "` -->`".
+-   DOCTYPEs must be "`<!DOCTYPE `" then the name then if either of the
+    system id or public id is non-empty a space, public id in
+    double-quotes, another space an the system id in double-quotes, and
+    then in any case "`>`".
+-   Processing instructions must be "`<?`", then the target, then a
+    space, then the data and then "`>`". (The HTML parser cannot emit
+    processing instructions, but scripts can, and the WebVTT to DOM
+    rules can emit them.)
+-   Template contents are represented by the string "content" with the
+    children below it.
+
+The *tag name string* is the local name prefixed by a namespace
+designator. For the HTML namespace, the namespace designator is the
+empty string, i.e. there's no prefix. For the SVG namespace, the
+namespace designator is "svg ". For the MathML namespace, the namespace
+designator is "math ".
+
+The *attribute name string* is the local name prefixed by a namespace
+designator. For no namespace, the namespace designator is the empty
+string, i.e. there's no prefix. For the XLink namespace, the namespace
+designator is "xlink ". For the XML namespace, the namespace designator
+is "xml ". For the XMLNS namespace, the namespace designator is "xmlns
+". Note the difference between "xlink:href" which is an attribute in no
+namespace with the local name "xlink:href" and "xlink href" which is an
+attribute in the xlink namespace with the local name "href".
+
+If there is also a "\#document-fragment" the bit following "\#document"
+must be a representation of the HTML fragment serialization for the
+context element given by "\#document-fragment".
+
+For example:
+
+    #data
+    <p>One<p>Two
+    #errors
+    3: Missing document type declaration
+    #document
+    | <html>
+    |   <head>
+    |   <body>
+    |     <p>
+    |       "One"
+    |     <p>
+    |       "Two"

+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.
+
+1. Definitions
+
+    "Adaptation" means a work based upon the Work, or upon the Work and other pre-existing works, such as a translation, adaptation, derivative work, arrangement of music or other alterations of a literary or artistic work, or phonogram or performance and includes cinematographic adaptations or any other form in which the Work may be recast, transformed, or adapted including in any form recognizably derived from the original, except that a work that constitutes a Collection will not be considered an Adaptation for the purpose of this License. For the avoidance of doubt, where the Work is a musical work, performance or phonogram, the synchronization of the Work in timed-relation with a moving image ("synching") will be considered an Adaptation for the purpose of this License.
+    "Collection" means a collection of literary or artistic works, such as encyclopedias and anthologies, or performances, phonograms or broadcasts, or other works or subject matter other than works listed in Section 1(f) below, which, by reason of the selection and arrangement of their contents, constitute intellectual creations, in which the Work is included in its entirety in unmodified form along with one or more other contributions, each constituting separate and independent works in themselves, which together are assembled into a collective whole. A work that constitutes a Collection will not be considered an Adaptation (as defined above) for the purposes of this License.
+    "Distribute" means to make available to the public the original and copies of the Work or Adaptation, as appropriate, through sale or other transfer of ownership.
+    "Licensor" means the individual, individuals, entity or entities that offer(s) the Work under the terms of this License.
+    "Original Author" means, in the case of a literary or artistic work, the individual, individuals, entity or entities who created the Work or if no individual or entity can be identified, the publisher; and in addition (i) in the case of a performance the actors, singers, musicians, dancers, and other persons who act, sing, deliver, declaim, play in, interpret or otherwise perform literary or artistic works or expressions of folklore; (ii) in the case of a phonogram the producer being the person or legal entity who first fixes the sounds of a performance or other sounds; and, (iii) in the case of broadcasts, the organization that transmits the broadcast.
+    "Work" means the literary and/or artistic work offered under the terms of this License including without limitation any production in the literary, scientific and artistic domain, whatever may be the mode or form of its expression including digital form, such as a book, pamphlet and other writing; a lecture, address, sermon or other work of the same nature; a dramatic or dramatico-musical work; a choreographic work or entertainment in dumb show; a musical composition with or without words; a cinematographic work to which are assimilated works expressed by a process analogous to cinematography; a work of drawing, painting, architecture, sculpture, engraving or lithography; a photographic work to which are assimilated works expressed by a process analogous to photography; a work of applied art; an illustration, map, plan, sketch or three-dimensional work relative to geography, topography, architecture or science; a performance; a broadcast; a phonogram; a compilation of data to the extent it is protected as a copyrightable work; or a work performed by a variety or circus performer to the extent it is not otherwise considered a literary or artistic work.
+    "You" means an individual or entity exercising rights under this License who has not previously violated the terms of this License with respect to the Work, or who has received express permission from the Licensor to exercise rights under this License despite a previous violation.
+    "Publicly Perform" means to perform public recitations of the Work and to communicate to the public those public recitations, by any means or process, including by wire or wireless means or public digital performances; to make available to the public Works in such a way that members of the public may access these Works from a place and at a place individually chosen by them; to perform the Work to the public by any means or process and the communication to the public of the performances of the Work, including by public digital performance; to broadcast and rebroadcast the Work by any means including signs, sounds or images.
+    "Reproduce" means to make copies of the Work by any means including without limitation by sound or visual recordings and the right of fixation and reproducing fixations of the Work, including storage of a protected performance or phonogram in digital form or other electronic medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce, limit, or restrict any uses free from copyright or rights arising from limitations or exceptions that are provided for in connection with the copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License, Licensor hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the duration of the applicable copyright) license to exercise the rights in the Work as stated below:
+
+    to Reproduce the Work, to incorporate the Work into one or more Collections, and to Reproduce the Work as incorporated in the Collections;
+    to create and Reproduce Adaptations provided that any such Adaptation, including any translation in any medium, takes reasonable steps to clearly label, demarcate or otherwise identify that changes were made to the original Work. For example, a translation could be marked "The original work was translated from English to Spanish," or a modification could indicate "The original work has been modified.";
+    to Distribute and Publicly Perform the Work including as incorporated in Collections; and,
+    to Distribute and Publicly Perform Adaptations.
+
+    For the avoidance of doubt:
+        Non-waivable Compulsory License Schemes. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme cannot be waived, the Licensor reserves the exclusive right to collect such royalties for any exercise by You of the rights granted under this License;
+        Waivable Compulsory License Schemes. In those jurisdictions in which the right to collect royalties through any statutory or compulsory licensing scheme can be waived, the Licensor waives the exclusive right to collect such royalties for any exercise by You of the rights granted under this License; and,
+        Voluntary License Schemes. The Licensor waives the right to collect royalties, whether individually or, in the event that the Licensor is a member of a collecting society that administers voluntary licensing schemes, via that society, from any exercise by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now known or hereafter devised. The above rights include the right to make such modifications as are technically necessary to exercise the rights in other media and formats. Subject to Section 8(f), all rights not expressly granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made subject to and limited by the following restrictions:
+
+    You may Distribute or Publicly Perform the Work only under the terms of this License. You must include a copy of, or the Uniform Resource Identifier (URI) for, this License with every copy of the Work You Distribute or Publicly Perform. You may not offer or impose any terms on the Work that restrict the terms of this License or the ability of the recipient of the Work to exercise the rights granted to that recipient under the terms of the License. You may not sublicense the Work. You must keep intact all notices that refer to this License and to the disclaimer of warranties with every copy of the Work You Distribute or Publicly Perform. When You Distribute or Publicly Perform the Work, You may not impose any effective technological measures on the Work that restrict the ability of a recipient of the Work from You to exercise the rights granted to that recipient under the terms of the License. This Section 4(a) applies to the Work as incorporated in a Collection, but this does not require the Collection apart from the Work itself to be made subject to the terms of this License. If You create a Collection, upon notice from any Licensor You must, to the extent practicable, remove from the Collection any credit as required by Section 4(b), as requested. If You create an Adaptation, upon notice from any Licensor You must, to the extent practicable, remove from the Adaptation any credit as required by Section 4(b), as requested.
+    If You Distribute, or Publicly Perform the Work or any Adaptations or Collections, You must, unless a request has been made pursuant to Section 4(a), keep intact all copyright notices for the Work and provide, reasonable to the medium or means You are utilizing: (i) the name of the Original Author (or pseudonym, if applicable) if supplied, and/or if the Original Author and/or Licensor designate another party or parties (e.g., a sponsor institute, publishing entity, journal) for attribution ("Attribution Parties") in Licensor's copyright notice, terms of service or by other reasonable means, the name of such party or parties; (ii) the title of the Work if supplied; (iii) to the extent reasonably practicable, the URI, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work; and (iv) , consistent with Section 3(b), in the case of an Adaptation, a credit identifying the use of the Work in the Adaptation (e.g., "French translation of the Work by Original Author," or "Screenplay based on original Work by Original Author"). The credit required by this Section 4 (b) may be implemented in any reasonable manner; provided, however, that in the case of a Adaptation or Collection, at a minimum such credit will appear, if a credit for all contributing authors of the Adaptation or Collection appears, then as part of these credits and in a manner at least as prominent as the credits for the other contributing authors. For the avoidance of doubt, You may only use the credit required by this Section for the purpose of attribution in the manner set out above and, by exercising Your rights under this License, You may not implicitly or explicitly assert or imply any connection with, sponsorship or endorsement by the Original Author, Licensor and/or Attribution Parties, as appropriate, of You or Your use of the Work, without the separate, express prior written permission of the Original Author, Licensor and/or Attribution Parties.
+    Except as otherwise agreed in writing by the Licensor or as may be otherwise permitted by applicable law, if You Reproduce, Distribute or Publicly Perform the Work either by itself or as part of any Adaptations or Collections, You must not distort, mutilate, modify or take other derogatory action in relation to the Work which would be prejudicial to the Original Author's honor or reputation. Licensor agrees that in those jurisdictions (e.g. Japan), in which any exercise of the right granted in Section 3(b) of this License (the right to make Adaptations) would be deemed to be a distortion, mutilation, modification or other derogatory action prejudicial to the Original Author's honor and reputation, the Licensor will waive or not assert, as appropriate, this Section, to the fullest extent permitted by the applicable national law, to enable You to reasonably exercise Your right under Section 3(b) of this License (right to make Adaptations) but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR 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, MERCHANTIBILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+    This License and the rights granted hereunder will terminate automatically upon any breach by You of the terms of this License. Individuals or entities who have received Adaptations or Collections from You under this License, however, will not have their licenses terminated provided such individuals or entities remain in full compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of this License.
+    Subject to the above terms and conditions, the license granted here is perpetual (for the duration of the applicable copyright in the Work). Notwithstanding the above, Licensor reserves the right to release the Work under different license terms or to stop distributing the Work at any time; provided, however that any such election will not serve to withdraw this License (or any other license that has been, or is required to be, granted under the terms of this License), and this License will continue in full force and effect unless terminated as stated above.
+
+8. Miscellaneous
+
+    Each time You Distribute or Publicly Perform the Work or a Collection, the Licensor offers to the recipient a license to the Work on the same terms and conditions as the license granted to You under this License.
+    Each time You Distribute or Publicly Perform an Adaptation, Licensor offers to the recipient a license to the original Work on the same terms and conditions as the license granted to You under this License.
+    If any provision of this License is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this License, and without further action by the parties to this agreement, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
+    No term or provision of this License shall be deemed waived and no breach consented to unless such waiver or consent shall be in writing and signed by the party to be charged with such waiver or consent.
+    This License constitutes the entire agreement between the parties with respect to the Work licensed here. There are no understandings, agreements or representations with respect to the Work not specified here. Licensor shall not be bound by any additional provisions that may appear in any communication from You. This License may not be modified without the mutual written agreement of the Licensor and You.
+    The rights granted under, and the subject matter referenced, in this License were drafted utilizing the terminology of the Berne Convention for the Protection of Literary and Artistic Works (as amended on September 28, 1979), the Rome Convention of 1961, the WIPO Copyright Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and the Universal Copyright Convention (as revised on July 24, 1971). These rights and subject matter take effect in the relevant jurisdiction in which the License terms are sought to be enforced according to the corresponding provisions of the implementation of those treaty provisions in the applicable national law. If the standard suite of rights granted under applicable copyright law includes additional rights not granted under this License, such additional rights are deemed to be included in the License; this License is not intended to restrict the license of any rights under applicable law.
