+requirements.
 
 * Python interpreter is installed on your operating system
 * :term:`setuptools` or :term:`distribute` is installed

+Create and Use a Virtual Python Environment

+Next let's create a `virtualenv` workspace for our project.  We will
+use the `VENV` environment variable instead of absolute path of the
+virtual environment.

+**On UNIX:**
+
+.. code-block:: text
+
+   $ export VENV=~/pyramidtut
+   $ virtualenv --no-site-packages $VENV

+Set the `VENV` environment variable.

+Versions of Python use different paths, so you will need to adjust the
+path to the command for your Python version.
