+===========================
+Utilities for z3c.testsetup
+===========================
+
+The `util` module defines some helper functions of general use.
+
+For most classes in this package, that accept packages as arguments,
+these packages can be delivered as real packages or as strings
+containing dotted names. To get a package of something, that is either
+a string with dotted names or a real package, the `get_package`
+function is provided.
+
+Such we can get a package from a dotted name string::
+
+   >>> from z3c.testsetup.util import get_package
+   >>> get_package('z3c.testsetup.tests.cave')
+   <module 'z3c.testsetup.tests.cave' from '...'>
+
+The dotted name string can be unicode::
+
+   >>> get_package(u'z3c.testsetup.tests.cave')
+   <module 'z3c.testsetup.tests.cave' from '...'>
+
+We can indeed pass a package as argument::
+
+   >>> from z3c.testsetup.tests import cave
+   >>> get_package(cave)
+   <module 'z3c.testsetup.tests.cave' from '...'>
+
+
+"""
