 * There were some typographical errors that needed fixing
 * before the program would compile.  This program does not
 * produce a frame with the components that look quite as
 * uniform in size as those shown in figure 6.7 on p. 124.
 * To make the first five buttons more uniform in size
 * uncomment the one line of code below.
