Replacement wp-config.php file for WP project repos

wp-config.php

<?php
/**
 * This is a `wp-config.php` replacement file for WP project repositories.
 *
 * It's purpose is to allow WP configurations such as database credentials,
 * auth salts and other constants to be environment-agnostic and live outside
 * of version control and outside the `public_html` docroot.
 *
 * Place your environment-specific `wp-config.php` one level above the docroot
 * in a `config` dir.
