ShrinkWrap is a drag and drop utility for handling all types
of disks and disk image files. Drag your image files into the
application and ShrinkWrap will automatically mount the image
in your desktop.
I case you don't know what a disk image is, it is a file that has
all the information contained in it to make a EXACT duplicate of a
disk, mainly for backup purposes. This exact duplication will
alleviate some of the installation problems with some installers
which demand the original program disk.
