+    <blockquote>
+      <p>Allows the user to customize the appearance and behavior of the
+        GUI . Please note: some preferences take effect immediately,
+        while others require DS9 to be restarted. Changes to the
+        preferences can be saved by selecting the <tt>Save</tt> button<tt>.
+        </tt>Use the <tt>Clear Preferences </tt>button to restore
+        default settings.</p>
+      <p>User preferences are stored in <tt>$HOME/.ds9.prf</tt>. DO NOT
+        EDIT this file, since it will be deleted or overwritten by DS9.
+        The file permissions must be group/world readonly.<br>
+      </p>
+      <p>Users may have several different preference files. DS9 looks
+        for a preference file with its own name. By default, if the
+        application is named <tt>ds9</tt>, it will look for <tt>.ds9.prf.</tt>
+        However, if the DS9 application is named <tt>foo</tt>, then DS9
+        will look for <tt>.foo.prf.</tt> In this manner, the user can
+        have several predefined preference files that are activated by
+        invoking DS9 with a different application names. </p>
