+ * end-user to use the plugin, and call the setup function of the dependent

+ *
+ * To avoid this, protection against double-registration has been introduced.
+ * The `event_handler_hook_use` and `loop_hook_use` functions will only allow
+ * one copy of the hook. The `event_handler_hook_append` and `loop_hook_append`
+ * functions will, on the other hand, just append the hooks, and not care about
+ * protection.
+ *
+ * The `event_handler_hook_add` and `loop_hook_add` functions are deprecated,
