This directory exists so that Subversion-based projects can share a single copy of the ``ez_setup`` bootstrap module for ``setuptools``, and have it automatically updated in their projects when ``setuptools`` is updated. For your convenience, you may use the following svn:externals definition:: ez_setup svn://svn.eby-sarna.com/svnroot/ez_setup You can set this by executing this command in your project directory:: svn propedit svn:externals . And then adding the line shown above to the file that comes up for editing. Then, whenever you update your project, ``ez_setup`` will be updated as well.
