This will change your ``$PATH`` to point to the virtualenv ``bin/``
, and update your prompt. Unlike workingenv, this is all it
+directory. Unlike workingenv, this is all it
does; it's a convenience. But if you use the complete path like
``/path/to/env/bin/python script.py`` you do not need to activate the
environment first. You have to use ``source`` because it changes the
environment in-place. After activating an environment you can use the
function ``deactivate`` to undo the changes.
+The ``activate`` script will also modify your shell prompt to indicate
+which environment is currently active. You can disable this behavior,
+which can be useful if you have your own custom prompt that already
+displays the active environment name. To do so, set the
+``VIRTUAL_ENV_DISABLE_PROMPT`` environment variable to any non-empty
+value before running the ``activate`` script.
