+    <p>
+      This sample demonstrates the LinkShiftingTool, which is an extra tool that can be installed in the ToolManager to allow users
+      to shift the end point of the link to be anywhere along the sides of the port with which it remains connected.
+    </p>
+    <p>
+      This only looks good for ports that occupy the whole of a rectangular node. If you want to restrict the user's permitted
+      sides, you can adapt the
+      <code>LinkShiftingTool.doReshape</code> method to do what you want.
