36  * #GAppInfoMonitor is a very simple object used for monitoring the app
37  * info database for changes (ie: newly installed or removed
38  * applications).
39  * 
40  * Call g_app_info_monitor_get() to get a #GAppInfoMonitor and connect
41  * to the "changed" signal.
42  * 
43  * In the usual case, applications should try to make note of the change
44  * (doing things like invalidating caches) but not act on it.  In
45  * particular, applications should avoid making calls to #GAppInfo APIs
46  * in response to the change signal, deferring these until the time that
47  * the data is actually required.  The exception to this case is when
48  * application information is actually being displayed on the screen
49  * (eg: during a search or when the list of all applications is shown).
50  * The reason for this is that changes to the list of installed
51  * applications often come in groups (like during system updates) and
52  * rescanning the list on every change is pointless and expensive.
53  *
