+    * Keep it as much similar to the default Python.framework for easier maintenance
+    * Add the following symlinks:
+{{{

+=== python24 ===
+python24 is already a framework installation, but should be changed to match
+the scheme from above.
+
+Maybe py-* requires the same transition as described for py25-* ports below, we will have to try out.
+
+=== 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.
+
+=== python30 ===
+Nobody should be using python30 productively yet. python30 port group was also
+not released yet.
+    * Make python30 install the same as other python versions.
+
+=== python26 ===
+After all was sorted out, we can add a python26 port in the same manner for the upcoming next python release.
