### XPA Access Points

> The XPA messaging system provides seamless communication between DS9 and other Unix programs, including X programs. It also provides an easy way for users to communicate with DS9 by executing XPA client commands in the shell or by utilizing such commands in scripts. Because XPA works both at the programming level and the shell level, it is a powerful tool for unifying any analysis environment.
