+    This sizer provides an empty buffer on one or more sides of it's
+    contents.  It can only hold a single widget, but that can be a
+    sizer containing other items if you wish.
+
+    The sizer is constructed with a parameter specifying which sides
+    should have the border.  You can use a logical OR of the following
+    values to specify the sides:
+
+        wxNORTH  -- the top side
+        wxSOUTH  -- the bottom side
+        wxEAST   -- the right side
+        wxWEST   -- the left side
+        wxALL    -- all sides
+
+    The width in pixels of the border is specified when the child
+    widget is Added to the sizer.
