   3   * Plugin Dependency Action Hooks.
   4   *
   5   * The purpose of the following hooks is to mimic the behavior of something
   6   * called 'plugin dependency' which enables a plugin to have plugins of their
   7   * own in a safe and reliable way.
   8   *
   9   * We do this in BuddyPress by mirroring existing WordPress hooks in many places
  10   * allowing dependent plugins to hook into the BuddyPress specific ones, thus
  11   * guaranteeing proper code execution only when BuddyPress is active.
  12   *
  13   * The following functions are wrappers for hooks, allowing them to be
  14   * manually called and/or piggy-backed on top of other hooks if needed.
  15   *
