Subject: 	* configure.in qt/Makefile.am: add qt/examples 	* qt/examples:
 Add QtDBus example programs: 	  - hello: Hello, World 	  - ping:
 Simple method-calling program 	  - pong: Simple object-exporting program (not
 using adaptors) 	  - complexping: Interactive method-calling program 
 	(also gets and sets properties). 	  - complexpong: Sample
 program exporting methods, signals and 		properties, using
 adaptors. 	  - dbus: Simple implementation of a generic method-calling 
 	program, similar to 'dbus-send', but with semantics 	
 similar to 'dcop'. 	  - chat: Simplistic chat program, implemented using
 signals 		and the system bus. Looks like IRC.
