// Asciidoctor API

/**
 * @namespace
 * @description
 * The main application interface (API) for Asciidoctor.
 * This API provides methods to parse AsciiDoc content and convert it to various output formats using built-in or third-party converters.
 *
 * An AsciiDoc document can be as simple as a single line of content,
 * though it more commonly starts with a document header that declares the document title and document attribute definitions.
 * The document header is then followed by zero or more section titles, optionally nested, to organize the paragraphs, blocks, lists, etc. of the document.
 *
 * By default, the processor converts the AsciiDoc document to HTML 5 using a built-in converter.
 * However, this behavior can be changed by specifying a different backend (e.g., +docbook+).
 * A backend is a keyword for an output format (e.g., DocBook).
 * That keyword, in turn, is used to select a converter, which carries out the request to convert the document to that format.
 *
 * @example
 * asciidoctor.convertFile('document.adoc', { 'safe': 'safe' }) // Convert an AsciiDoc file
 *
 * asciidoctor.convert("I'm using *Asciidoctor* version {asciidoctor-version}.", { 'safe': 'safe' }) // Convert an AsciiDoc string
 *
 * const doc = asciidoctor.loadFile('document.adoc', { 'safe': 'safe' }) // Parse an AsciiDoc file into a document object
 *
 * const doc = asciidoctor.load("= Document Title\n\nfirst paragraph\n\nsecond paragraph", { 'safe': 'safe' }) // Parse an AsciiDoc string into a document object

 *

 *
 * 1. After the source lines are normalized, {{@link Extensions/Preprocessor}}s modify or replace
 *    the source lines before parsing begins. {{@link Extensions/IncludeProcessor}}s are used to
 *    process include directives for targets which they claim to handle.
 * 2. The Parser parses the block-level content into an abstract syntax tree.
 *    Custom blocks and block macros are processed by associated {{@link Extensions/BlockProcessor}}s
 *    and {{@link Extensions/BlockMacroProcessor}}s, respectively.
 * 3. {{@link Extensions/TreeProcessor}}s are run on the abstract syntax tree.
 * 4. Conversion of the document begins, at which point inline markup is processed
 *    and converted. Custom inline macros are processed by associated {InlineMacroProcessor}s.
 * 5. {{@link Extensions/Postprocessor}}s modify or replace the converted document.
 * 6. The output is written to the output stream.
 *
 * Extensions may be registered globally using the {Extensions.register} method
 * or added to a custom {Registry} instance and passed as an option to a single
 * Asciidoctor processor.
 *
 * @example
 * asciidoctor.Extensions.register(function () {
 *   this.block(function () {
 *     const self = this
 *     self.named('shout')
 *     self.onContext('paragraph')
