- * <code>Assert</code> is useful for for embedding runtime sanity checks

- * thrown when something is misbehaving. Assertion failures are invariably
- * unspecified behavior; consequently, clients should never rely on
- * these being thrown (or not thrown). <b>If you find yourself in the

- * certainly written your program incorrectly.</b>
