 * Author: <a href="http://lukemcdonald.com">Luke McDonald</a>
 * Version: 1.0.0

 * Load WPCOM compatability file.
 *
 * Themes can define WordPress.com-specific code by adding a wpcom.php file in
 * either an /inc or /includes folder. This file can be used for defining
 * palettes for the Customizer, the $themecolors global, and anything else that
 * should only apply to the WordPress.com environment.
 *
 * The including happens on the after_setup_theme hook, but at a high priority:
 * add_action( 'after_setup_theme', 'wpcom_load_theme_compat_file', 0 );
 *
 * Including happens much like functions.php. If the file is present in a child
 * theme, it will be loaded from there first; if it's also present in the parent
 * theme, that will also be included immediately afterwards.
