+ * #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.
