    // 1. No leading slash in paths,
    //    e.g. in `url.parse('http://foo?bar')` pathname is ``, not `/`
    
    // 2. Backslashes are not replaced with slashes,
    //    so `http:\\example.org\` is treated like a relative path
    
    // 3. Trailing colon is treated like a part of the path,
    //    i.e. in `http://example.org:foo` pathname is `:foo`
    
    // 4. Nothing is URL-encoded in the resulting object,
    //    (in joyent/node some chars in auth and paths are encoded)
    
    // 5. `url.parse()` does not have `parseQueryString` argument
    
    // 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
    //    which can be constructed using other parts of the url.

  	 * class MarkdownIt

  	 *
  	 * ##### Usage
  	 *
  	 * ```javascript
  	 * // node.js, "classic" way:
  	 * var MarkdownIt = require('markdown-it'),
  	 *     md = new MarkdownIt();
  	 * var result = md.render('# markdown-it rulezz!');
  	 *
  	 * // node.js, the same, but with sugar:
  	 * var md = require('markdown-it')();
  	 * var result = md.render('# markdown-it rulezz!');
  	 *
  	 * // browser without AMD, added to "window" on script load
  	 * // Note, there are no dash.
  	 * var md = window.markdownit();
  	 * var result = md.render('# markdown-it rulezz!');
  	 * ```
  	 *
  	 * Single line rendering, without paragraph wrap:
  	 *
  	 * ```javascript
  	 * var md = require('markdown-it')();
  	 * var result = md.renderInline('__markdown-it__ rulezz!');
  	 * ```
  	 **/
    /**
  	 * new MarkdownIt([presetName, options])
  	 * - presetName (String): optional, `commonmark` / `zero`
  	 * - options (Object)
  	 *
  	 * Creates parser instanse with given config. Can be called without `new`.
  	 *
  	 * ##### presetName
  	 *
  	 * MarkdownIt provides named presets as a convenience to quickly
  	 * enable/disable active syntax rules and options for common use cases.
  	 *
  	 * - ["commonmark"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -
  	 *   configures parser to strict [CommonMark](http://commonmark.org/) mode.
  	 * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -
  	 *   similar to GFM, used when no preset name given. Enables all available rules,
  	 *   but still without html, typographer & autolinker.
  	 * - ["zero"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -
  	 *   all rules disabled. Useful to quickly setup your config via `.enable()`.
  	 *   For example, when you need only `bold` and `italic` markup and nothing else.
  	 *
  	 * ##### options:
  	 *
  	 * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!
  	 *   That's not safe! You may need external sanitizer to protect output from XSS.
  	 *   It's better to extend features via plugins, instead of enabling HTML.
  	 * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags
  	 *   (`<br />`). This is needed only for full CommonMark compatibility. In real
  	 *   world you will need HTML output.
  	 * - __breaks__ - `false`. Set `true` to convert `\n` in paragraphs into `<br>`.
  	 * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.
  	 *   Can be useful for external highlighters.
  	 * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.
  	 * - __typographer__  - `false`. Set `true` to enable [some language-neutral
  	 *   replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +
  	 *   quotes beautification (smartquotes).
  	 * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement
  	 *   pairs, when typographer enabled and smartquotes on. For example, you can
  	 *   use `'«»„“'` for Russian, `'„“‚‘'` for German, and
  	 *   `['«\xA0', '\xA0»', '‹\xA0', '\xA0›']` for French (including nbsp).
  	 * - __highlight__ - `null`. Highlighter function for fenced code blocks.
  	 *   Highlighter `function (str, lang)` should return escaped HTML. It can also
  	 *   return empty string if the source was not changed and should be escaped
  	 *   externaly. If result starts with <pre... internal wrapper is skipped.
  	 *
  	 * ##### Example
  	 *
  	 * ```javascript
  	 * // commonmark mode
  	 * var md = require('markdown-it')('commonmark');
  	 *
  	 * // default mode
  	 * var md = require('markdown-it')();
  	 *
  	 * // enable everything
  	 * var md = require('markdown-it')({
  	 *   html: true,
  	 *   linkify: true,
  	 *   typographer: true
  	 * });
  	 * ```
  	 *
  	 * ##### Syntax highlighting
  	 *
  	 * ```js
  	 * var hljs = require('highlight.js') // https://highlightjs.org/
  	 *
  	 * var md = require('markdown-it')({
  	 *   highlight: function (str, lang) {
  	 *     if (lang && hljs.getLanguage(lang)) {
  	 *       try {
  	 *         return hljs.highlight(str, { language: lang, ignoreIllegals: true }).value;
  	 *       } catch (__) {}
  	 *     }
  	 *
  	 *     return ''; // use external default escaping
  	 *   }
  	 * });
  	 * ```
  	 *
  	 * Or with full wrapper override (if you need assign class to `<pre>`):
  	 *
  	 * ```javascript
  	 * var hljs = require('highlight.js') // https://highlightjs.org/
  	 *
  	 * // Actual default values
  	 * var md = require('markdown-it')({
  	 *   highlight: function (str, lang) {
  	 *     if (lang && hljs.getLanguage(lang)) {
  	 *       try {
  	 *         return '<pre class="hljs"><code>' +
  	 *                hljs.highlight(str, { language: lang, ignoreIllegals: true }).value +
  	 *                '</code></pre>';
  	 *       } catch (__) {}
  	 *     }
  	 *
  	 *     return '<pre class="hljs"><code>' + md.utils.escapeHtml(str) + '</code></pre>';
  	 *   }
