 * Node.js; it is more suitable to development and automated processes.
 * If you are a user or non-developer without such an environment set up,
 * then you might rather bootstrap using your web browser instead; you can
 * do so by directing your web browser to `bootstrap.html', located in the
 * same directory as this file.
 *
 * To perform the entire bootstrapping process, simply invoke this script:
 *   $ node bootstrap.js
 *
 * For more information on each aspect of the process, see the individual
 * files in `./bootstrap/'.
