+ * This class implements a very simple IPC mechanism for KDE. You can send
+ * a message of a predefined type to either a specific application, or to all
+ * KDE application on the current display. The message can carry one integer of
+ * data.
+ *
+ * KIPC is mainly used in KDE for sending "Change Messages", i.e. a message to
+ * all KDE apps that a certain setting (the font, for example) has changed.
+ * For anything more complex it is recommended to use DCOP -- the Desktop
+ * Communications Protocol.
+ *
+ * Messages with id code < 32 are called "System Messages". These are
+ * directly handled by KApplication. Examples are: PaletteChanged and
+ * StyleChanged. Messages with id code >= 32 are user messages. KApplication
+ * emits the signal kipcMessage(id,arg) for each user message it receives.
+ *
+ * KIPC is implemented using X11 ClientMessage events.

+ * @see KApplication::kipcMessage()
