Difference between woody and potato

[Marshal Kar-Cheung Wong <masee@usa.net>]

I'm a bit confused about woody and potato.  I though that potato is
always the newest, bleeding edge distribution.  And that woody is the
code-name for the 2.2 release.  So why is unstable pointing to woody,
and frozen to potato?  I found this out when I tried to get gimp1.1
and found it not there, even when my sources.list is pointing to
unstable.  Mind you, gimp1.1 should be in unstable anyways, I think,
since it's going into 2.2.  (or is it?)  Clarification and corrections
are appreciated.

Dazed and Confused. :)
