Remove the '-' line, replace it with the '+' line.

Both if need be - but definitely in your runtime path.

cd to your zope INSTANCE_HOME, then you can invoke the python
interpreter with either of:

  ./bin/zopectl debug
or
  ./bin/debugzope

This will add zope (and $INSTANCE_HOME/lib/python) to your python path
and process all the zcml files.  It will also add 'app' to your python
session...

>>> app
<zope.app.debug.debug.Debugger object at 0xb741010c>
>>> app.root()
<zope.app.folder.folder.Folder object at 0xb4fe706c>
>>> list(app.root())
[u'Folder1', u'Folder2']

>>> from zope import schema
>>> dir(schema)
