Committed with small changes: I used the new ‘install-file’ procedure
instead of ‘copy-file’, simplified the synopsis and description, and
fixed the license (it’s mainly ASL 2.0.)

Thanks!

Thank you!

I appreciate when you make those small changes, really helps speed up
contributions and I don't take your efforts lightly. Thanks!

Also - I'm seeing now what you're talking about with the licensing.. thanks
for looking deeper.
