	BROOM -- sweep clean a disk

	This program allocates a file on each disk
	the size of which is equal to the number of free blocks
	on the volume, then writes a blank buffer to each block.
	This effectively erases the free space on the disk so that
	deleted files are truely deleted.

			BRM> dev:,dev:,...

	where dev is a mounted Files-11 device only.  It is strongly
	recommended that BROOM is only used on queisent devices as
	the program allocates every available block on the device
	to the temporary file.
