"""
Facilitates unit tests which requires an acquirable REQUEST from
ZODB objects

Usage:

    import makerequest
    app = makerequest.makerequest(Zope2.app())

You can optionally pass stdout to be used by the response,
default is sys.stdout.

If you don't want to start a zope app in your test, you can wrap other
objects, but they must support acquisition and you should only wrap
your root object.
