/**
 * Extends the main {@link Puppeteer} class with Node specific behaviour for fetching and
 * downloading browsers.
 *
 * If you're using Puppeteer in a Node environment, this is the class you'll get
 * when you run `require('puppeteer')` (or the equivalent ES `import`).
 *
 * @remarks
 *
 * The most common method to use is {@link PuppeteerNode.launch | launch}, which
 * is used to launch and connect to a new browser instance.
 *
 * See {@link Puppeteer | the main Puppeteer class} for methods common to all
 * environments, such as {@link Puppeteer.connect}.
 *
 * @example
 * The following is a typical example of using Puppeteer to drive automation:
 * ```js
 * const puppeteer = require('puppeteer');
 *
 * (async () => {
 *   const browser = await puppeteer.launch();
 *   const page = await browser.newPage();
 *   await page.goto('https://www.google.com');
 *   // other actions...
 *   await browser.close();
 * })();
 * ```
 *
 * Once you have created a `page` you have access to a large API to interact
 * with the page, navigate, or find certain elements in that page.
 * The {@link Page | `page` documentation} lists all the available methods.
 *

     * There is no guarantee it will work with any other version.
     * Use `executablePath` option with extreme caution.
     * If Google Chrome (rather than Chromium) is preferred, a {@link https://www.google.com/chrome/browser/canary.html | Chrome Canary} or {@link https://www.chromium.org/getting-involved/dev-channel | Dev Channel} build is suggested.
     * In `puppeteer.launch([options])`, any mention of Chromium also applies to Chrome.
