+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.

+         * 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
+         * method must return. The IO driver will then swallow the next
+         * character if it is an LF to coalesce CRLF.

+ * 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.

+ * nsHtml5StreamParserPtr. Upon creation, nsHtml5StreamParserPtr addrefs the

+ * 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

+ * 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.

+ * location pointed to by the nsIContent**.
+ *
+ * Since tree ops are in a queue, the node creating tree op will always
