I think that's what I'm doing with this line in apt.conf:
  APT::Default-Release "testing";
so `aptitude install foo` will install the testing version by default,
but if I specifically want something else I can use options to get
what I want.  (I have a big preferences file but it's entirely
produced by apt-listbugs.)

I would like to take this opportunity to ask for clarification about
something.  Given my apt.conf line above, is the difference between
these
(1)  aptitude install foo/unstable
(2)  aptitude -t unstable install foo
that (1) will get the unstable version of foo but the testing versions
of any unsatisfied dependencies, whereas (2) will get the unstable
versions of foo's dependencies and foo itself?

Thanks,
Adam
