* #GTypeModule provides a simple implementation of the #GTypePlugin
* interface. The model of #GTypeModule is a dynamically loaded module
- * which implements some number of types and interface
- * implementations. When the module is loaded, it registers its types
- * and interfaces using g_type_module_register_type() and
- * g_type_module_add_interface(). As long as any instances of these
- * types and interface implementations are in use, the module is kept
- * loaded. When the types and interfaces are gone, the module may be
- * unloaded. If the types and interfaces become used again, the module
- * will be reloaded. Note that the last unref can not happen in module
- * code, since that would lead to the caller's code being unloaded before
- * g_object_unref() returns to it.
