/**
 * #GAppInfoMonitor is a very simple object used for monitoring the app
 * info database for changes (ie: newly installed or removed
 * applications).
 * 
 * Call g_app_info_monitor_get() to get a #GAppInfoMonitor and connect
 * to the "changed" signal.
 * 
 * In the usual case, applications should try to make note of the change
 * (doing things like invalidating caches) but not act on it.  In
 * particular, applications should avoid making calls to #GAppInfo APIs
 * in response to the change signal, deferring these until the time that
 * the data is actually required.  The exception to this case is when
 * application information is actually being displayed on the screen
 * (eg: during a search or when the list of all applications is shown).
 * The reason for this is that changes to the list of installed
 * applications often come in groups (like during system updates) and
 * rescanning the list on every change is pointless and expensive.
 *
 * Since: 2.40
