+            [Python] SF Bug #1297
+
+            Resolve several issues related to python imports.
+            For example, it's now possible to import modules having the same module
+            names, but belonging in different packages.
+            
+            From the user's viewpoint, this patch gives a little bit more control on
+            import statements generated by SWIG. The user may choose to use relative
+            or absolute imports.
+            
+            Some details:
+              - we (still) generate import statements in the form 'import a.b.c' which
+                corresponds to absolute imports in python3 and (the only available)
+                ambiguous one in python2.
+              - added -relativeimport option to use explicit relative import syntax
+                (python3),
+
+            The "Python Packages" section in the documentation discusses how to work
+            with importing packages including the new -relativeimport command line option.
