Proposal:

	Integrate diffstat into Solaris.

Detail:

        diffstat reads the output of diff and displays a histogram
        of the insertions, deletions, and modifications per-file.
        It is useful for reviewing large, complex patch files.
        It reads from one or more input files which contain output
        from diff, producing a  histogram of the total lines changed
        for each file referenced.  If the input filename ends with
	.bz2, .Z or .gz, diffstat will read the uncompressed data
        via a pipe from the corresponding program.

	The current version of diffstat is 1.45 at the time of this
	case.

	Example output:
