/**
 * Attach bbPress to WordPress
 *
 * bbPress uses its own internal actions to help aid in third-party plugin
 * development, and to limit the amount of potential future code changes when
 * updates to WordPress core occur.
 *
 * These actions exist to create the concept of 'plugin dependencies'. They
 * provide a safe way for plugins to execute code *only* when bbPress is
 * installed and activated, without needing to do complicated guesswork.
 *
 * For more information on how this works, see the 'Plugin Dependency' section
 * near the bottom of this file.
