I received this demo in the mail from Big Noise Software.
The two files info.txt and install.txt are two leaflets that
came with the disks.  To install the demo, unzip the CADENZA.ZIP
archive to a floppy or a temporary place on your hard drive, and 
run the windows program INSTALL.EXE found there.  The installed 
application takes up about 2 meg on the hard drive.
