Actually, it depends on the regex interpreter.  As I recall, in PERL, you
use (...) to represent a group of characters that need to be remembered
for later recalling.  Under sed, \(...\) is used to do the same.  (Perl
also uses $1 instead of \1 for recalling, doesn't it?)

If you don't put the backslashes in front of ( or ), you match the
parenthesis characters, I think.  The same *seems* to be true for curly
braces... on Sed, anyway.

   SED: See smoke-emitting diode

   Smoke emitting diode: An incorrectly connected diode, probably a
      light-emitting diode, in the process of losing its "magic smoke"
      and becoming a "friode".
