+    The modified CPython library.
 .. _`modify modules`:
 by default and CPython has a number of places where it relies
 on some classes being old-style.
-If you want to change a module or test contained in ``lib-python/2.7``
-then make sure that you copy the file to our ``lib-python/modified-2.7``
-directory first.  In mercurial commandline terms this reads::
-    $ hg cp lib-python/2.7/ lib-python/modified-2.7/
-and subsequently you edit and commit
-``lib-python/modified-2.7/``.  This copying operation is
-important because it keeps the original CPython tree clean and makes it
-obvious what we had to change.
+We just maintain those changes in place,
+to see what is changed we have a branch called `vendot/stdlib`
+wich contains the unmodified cpython stdlib
