-Tests
-=====
-
-Serious tests are missing, but we're checking PEP8 conformity of our syntax on
-both Python 2 and 3 using ``tox``.  You can run the tests locally via::
-
-    $ python setup.py test
-
-No prerequisites are required, all test dependencies will be installed
-automatically by ``tox`` in virtual environments created on the fly.
-Unfortunately, you'll have to install ``virtualenv`` for this to work, though.
-
-To remove all build files and folders including Python byte code you can run::
-
-    $ python setup.py clean
