    <blockquote>
      <p>The <a href="http://hea-www.harvard.edu/RD/xpa/index.html">XPA
        </a> messaging system provides seamless communication between
        DS9 and other Unix programs, including X programs, Perl, <a
          href="http://space.mit.edu/cxc/software/slang/modules/xpa/">
          S-Lang,</a> and Tcl/Tk. 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.</p>
