+/**
+ * <p>A simple logging interface abstracting logging APIs.  In order to be
+ * instantiated successfully by {@link LogFactory}, classes that implement
+ * this interface must have a constructor that takes a single String
+ * parameter representing the "name" of this Log.</p>
+ *
+ * <p> The six logging levels used by <code>Log</code> are (in order):
+ * <ol>
+ * <li>trace (the least serious)</li>
+ * <li>debug</li>
+ * <li>info</li>
+ * <li>warn</li>
+ * <li>error</li>
+ * <li>fatal (the most serious)</li>
+ * </ol>
+ * The mapping of these log levels to the concepts used by the underlying
+ * logging system is implementation dependent.
+ * The implemention should ensure, though, that this ordering behaves
+ * as expected.</p>
+ *
+ * <p>Performance is often a logging concern.
+ * By examining the appropriate property,
+ * a component can avoid expensive operations (producing information
+ * to be logged).</p>
+ *
+ * <p> For example,
+ * <code><pre>
+ *    if (log.isDebugEnabled()) {
+ *        ... do something expensive ...
+ *        log.debug(theResult);
+ *    }
+ * </pre></code>
+ * </p>
+ *
+ * <p>Configuration of the underlying logging system will generally be done
+ * external to the Logging APIs, through whatever mechanism is supported by
+ * that system.</p>
