virtualenvwrapper adds several hook points you can use to change your settings, shell environment, or other configuration values when creating, deleting, or moving between environments. These hooks are exposed in two ways. :ref:`scripts` allows a user to perform generic actions for every virtualenv in your environment, including customization of virtualenv creation. :ref:`plugins` makes it possible to share common behaviors between systems and developers.
