program, it only took a couple of hours.  Heavily tested: it didn't core dump
examining my 20GB FAT32 partition, ship it!

Actually, I did imagezip/imageunzip a FAT12 DOS floppy.  Since imagezip
files are a minimum of 1MB (the chunk size), it is probably not practical
for saving 1.4MB floppies :-)

Also, updated the man page.
