-  // Note: this is equivalent to unicode case folding; unicode normalization
-  // is a different step that is not required here.

- * ```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
- *   (`
`). 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 `
`.
- * - __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 `):
- *
- * ```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 '
' +
- *                hljs.highlight(lang, str, true).value +
- *                '
';
- *       } catch (__) {}
- *     }
- *
- *     return '
' + md.utils.escapeHtml(str) + '
';
- *   }
- * });
- * ```

-// Changes from joyent/node:
-//
-// 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.
-//
