3. Report percent statements covered by function:

	$ go tool covdata func -i=profiledir
	cov-example/p/p.go:12:		emptyFn			0.0%
	cov-example/p/p.go:32:		Small			100.0%
	cov-example/p/p.go:47:		Medium			90.9%
	...
	$

4. Convert coverage data to legacy textual format:

	$ go tool covdata textfmt -i=profiledir -o=cov.txt
