	This utility reads the BITMAP.SYS file in the [0,0] directory on
	a disk specified by the user. A one page report is generated
	containing information on fragmentation of the disk. This version
	only examines the AVAILABLE space on the disk. Future versions
	will include USED space in the report. 

	The percent of fragmentation is a number that you will have to
	compare to the amount of free space.  For example, if a disk has
	only 100 free blocks, being 90% fragmented doesn't mean much. On
	the other hand, if a disk has 800,000 free blocks being 50%
	fragmented is significant.  The importance of fragmentation must
	also be weighted by your applications and disk activity. 

	The percentage is calculated by dividing the number of fragments
	(regardless of the fragment size) by the worst case number of
	fragments. The worst case number of fragments is equal to the
	number of free blocks divided by cluster size. 

	EXAMPLE:

	The disk has 600,000 blocks available and a cluster size of 3.
	There are 20,000 fragments of varying sizes on the disk. 

		maximum fragment = 200,000 = 600,000 / 3

	This is the worst case since 200,000 fragments would indicated
	that no two available disk clusters were contiguous. 

		percent fragmented = 10% = 20,000 / 200,000
