| /** |
| * This interface supplies the API for providing feedback to the user from the <code>Mojo</code>, using standard |
| * <code>Maven</code> channels.<br> |
| * There should be no big surprises here, although you may notice that the methods accept |
| * <code>java.lang.CharSequence</code> rather than <code>java.lang.String</code>. This is provided mainly as a |
| * convenience, to enable developers to pass things like <code>java.lang.StringBuffer</code> directly into the logger, |
| * rather than formatting first by calling <code>toString()</code>. |
