Some may challenge the 'no muss, no fuss' part. ;)

My one real regret with this solution is for those shops which implement
this, but which are not (yet :) entirely comfortable with Perl.  For those,
Mark's preamble above may suffice as a comment in the command file.

Perl actually has a neat feature to help with the readability of
such expressions -- more in line with Mark's detailed deconstruction
a day or two ago -- but the max length of the info string likely
prevents it from being put to good use here.  (I've not tried.)

Perl's extensive use of "non-letters" may present an initial hurdle
(much like Greek characters did in math classes, or the wacky
syntax of Objective C), but it should not be a showstopper.
