Hi Ludovic,

Thanks for the quick feedback.  I've attached a new patch that
incorporates almost all of your suggestions, and also includes a basic
find/replace in the manual (though more work is needed there).

Done.

Indeed.  The reason I initially kept the test updates separated is
because I wasn't sure if we wanted to continue supporting the old style
"guix-package" and friends.  However, we agreed on IRC to abandon the
old style, so that's what this patch now does.

Done.

I now support --version and --help, but I didn't see how to use SRFI-37
in the main driver, because it doesn't know the full set of options to
accept.

Done.

Here's the new patch, compressed this time.  Please let me know what you
think.  I think this might be about ready to push.
