Change subject: Documentation: add util/pmh7tool to util.md
......................................................................

Patch Set 1:
> There is a script under util called "util_readme" that auto
> generates `Documentation/util.md` and `util/README.md` based on the
> `description.md` file under each util directory.  Can you add a
> `description.md` for pmh7tool and run the script instead and submit
> those as changes?

Sorry, didn't know that. Sure.
