|
* The Contiki program handler is responsible for the Contiki menu and
|
|
* the desktop icons, as well as for loading programs and displaying a
|
|
* dialog with a message telling which program that is loading.
|
|
*
|
|
* The program handler also is responsible for starting the
|
|
* screensaver when the CTK detects that it should be started.
