+ * A very flexible layout manager. Components are laid out by defining the
+ * relationships between them. The relationships are expressed as
+ * {@link Spring}s. You can attach a Spring for each edge of a component and
+ * link it to an edge of a different component. For example, you can say,
+ * the northern edge of component A should be attached to the southern edge
+ * of component B, and the space between them should be something between
+ * x and y pixels, and preferably z pixels.
+ * <p>While quite simple, this layout manager can be used to emulate most other
+ * layout managers, and can also be used to solve some layout problems, which
+ * would be hard to solve with other layout managers.</p>
