Ok I was mistaken -- only remembering from rcs where one had to put
a 'cookie' containing rcs-variables that would be substituted.

Which variables you put would decide which pieces of info were
available; the info was in-band, if at all.  Nowadays its all there, its
out-of-band and the natural usage therefore is different.

You've got some good answers.

I'd like to point out that this might make a good entry in a Python FAQ list...
