Test licenser
================

The obligatory imports::

    >>> import licenser
    >>> from licenser import licenses
    >>> import os

Sanity check::

    >>> assert os.path.exists(directory)

Test MPL license::

    >>> license = licenses.MPL()
    >>> variables = {'author': 'Jeff Hammel', 'email': 'k0s@k0s.org'}
    >>> license.interpolate(directory, variables)
