+  <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.
