5. Merge profiles together:

	$ go tool covdata merge -i=indir1,indir2 -o=outdir -modpaths=github.com/go-delve/delve
	$

6. Subtract one profile from another

	$ go tool covdata subtract -i=indir1,indir2 -o=outdir
	$

7. Intersect profiles

	$ go tool covdata intersect -i=indir1,indir2 -o=outdir
	$

8. Dump a profile for debugging purposes.

	$ go tool covdata debugdump -i=indir
	<human readable output>
	$
