"""Dynamically selected dependencies for Proboscis.
If Nose is installed, Proboscis will use it. Otherwise Proboscis will use the
default unittest framework, in order to function in IronPython and Jython. It
also supports Python 2.5 in order to work with Jython.

unittest.TestCase.skipTest. If that method isn't available (anything under
