+"""Make LocationProxies security-aware.
+
+This module does a somewhat hard hack and is intended to be refactored
+at some point, but helps avoiding to have zope.location depend on
+zope.security.
+
+We start with an unlocated class that will be wrapped by a
+LocationProxy:
+
+>>> class Unlocated(object):
+...     a = 'a'
+
+>>> unlocated = Unlocated()
+
+Now we create a location proxy around it:
+
+>>> from zope.location.location import LocationProxy
+>>> located = LocationProxy(unlocated)
+
+We define a checker for the unlocated object, which will also be
+used by the security proxy as the LocationProxy defines
+__Security_checker__:
+
+>>> from zope.security.checker import NamesChecker, defineChecker
+>>> unlocatedChecker = NamesChecker(['a'])
+>>> defineChecker(Unlocated, unlocatedChecker)
+
+>>> from zope.security.proxy import ProxyFactory
+>>> secure_located = ProxyFactory(located)
+>>> secure_located.a
+'a'
