Hmm -- fair answer.  I was kind of thinking that on FreeBSD I should
maybe do such work in csh as the standard shell, but it occurs to me that
I'd probably be pretty hard-pressed to find a FreeBSD system without sh
on it.

. . . and I *do* use Perubython (or rather, Perubyl) for anything complex
enough to use more than one or two conditionals in it.  I haven't met a
shell (other than one derived from a general purpose programming
language) yet that doesn't annoy me beyond that level of complexity for
