-The py-* ports require the same transition as described for py25-* ports below.

 === python25 ===
 In order to safely upgrade especially python25 to a framework, we need:
 
-    * A new python25 port group, which has to be released with one of the next
-      MacPorts version. Efforts on this branch have to be coordinated with a
-      release (targeting 1.6.1 or 1.6.2).
-
-    * All py25-* ports have to be removed *before* upgrading python25 itself,
-      because we change lib/python2.5 from a directory into a symlink.
-      Otherwise you will see errors with file_map.db.
-
-    * Therefore we need some hook inside python25 to fire up on upgrading
-      non-framework to framework. E.g. it would have to do, save a list of all
-      installed py25-* ports before and uninstall them. After successful
-      installation of python25, install these ports again. Because of the
-      directory-to-symlink change, deactivate/activate does not work.
-      This will be the main challenge.
-
-    * There are two mutually exclusive ways to do the transitions.
-      They get described here by pseudo-code. Feel free to replace by
-      real commandos.
