Excellent.  Thanks.  I only used the backticks because they'd already
been used in that script, and I couldn't remember how strict we were
being about our build environment.

I'll change them all to $(...).  I haven't personally used a backtick
in my own scripts for...  decades?  I'd actually forgotten the baroque
behavior of backlash quoting.

And echo --> printf.  Again, I was nervous about introducing it.
