Short: zerofills all empty blocks on any device

(Giuseppe Sacco)
ZeroUno is a program that clears all unused sectors of a partition of
an Exec device. It is particularly useful together with Antonio Schifano's
compressdisk.device, to give back disk space on the device work disk after
deleting some files on a virtual partition. Some strange people use ZeroUno
from time to time for zeroing (!) unused sectors of hard disks subject to
data loss, in order to let Dave Haynie's DiskSalv recover only
the interesting files. Likewise, it might be useful to make sure none
could be able to recover some files you deleted......
