We implemented the following scheme, inspired by the 'testresult' svn
directory: there is a distinct svn directory somewhere in 'pypy/branch'
that contains a copy of a known and stable revision of a selection of
directories, namely 'interpreter', 'module' and 'objspace' without
'flow'. This is to be checked out *inside* pypy/translator/goal. Then
translate_pypy does some minor hacking of 'pypy.__path__' to let the
directories from the branch override the directories from the complete
working copy. Instructions on what to checkout exactly are given when
you try to run translate_pypy.py.
The scaled-down "branch" isn't meant for active development, and will
never be merged back into the trunk. Occasionally, further fixes in the
trunk that are needed to make the annotator happy are merged into the
