+Here are the programs in the Qt tutorial. The tutorial itself is in
+../doc/html/tutorial.html (or http://doc.trolltech.com/3.0/tutorial.html).
+
+Typing 'make' in this directory builds all the programs (t1/t1,
+t2/t2, t3/t3 and so on). Typing 'make' in each subdirectory builds
+just that tutorial program.
+
+Feel free to send comments about the tutorial to qt-bugs@trolltech.com.
