SYNOPSIS
        ddfs-freemap [OPTIONS] FREEMAP

DESCRIPTION
        -r, --range=RANGE
                specifies ranges of sequential free blocks to group
 output result.

        RANGE is a monotonically increasing, space-separated sequen
ce of numbers: RANGE='R1 R2 ... R(n-1) Rn'.  Available free blocks
statistic will be displayed in a table with n+1 rows and grand tota
l.  Each row contains statistic of sequential free blocks withing a
 specified ranges: [1; R1], [R1+1; R2], ..., [R(n-1)+1; Rn],[R(n+1)
; INF].

        For example: RANGE='1 2 3 10 50 1000'.
Ranges: 1, 2, 3, [4; 10], [11; 50], [51; 1000], [1001; INF].

        Statistic table contains the following columns:

        #seq free blocks
                range of sequential free blocks
        min
                minimal number of sequential free blocks within a r
ange
        max
                maximum number of sequential free blocks within a r
ange
        avg
                average number of sequential free blocks within a r
ange
        avg
                average number of sequential free blocks within a r
ange
        std
                standard deviation of a number of sequential free b
locks within a range
        #frag
                total number of distinct fragments containing speci
fied number of sequential free blocks
        #blocks
                total number of free blocks within a range
        pct
                percent of total free blocks (by size)
        size
                total size of free blocks within a range
