I'm not aware of any regexp idiom for lowercasing something. That's why
I say that you'd probably have to do this same thing for B/b, C/c, etc.
Of course, you could probably attack this with Perl, Python or Awk, and
there are built-in functions for lowercasing things. But that's a more
complex procedure. It *might* save you time, depending on how long it
took you to code it.
