+ * A <code>java.util.logging</code> (JUL) Handler for Android.

+ * If you want fine-grained control over MTM's logging, you can copy this
+ * class to your code base and call the static {@link #initialize()} method.
+ * </p>
+ * <p>
+ * This JUL Handler passes log messages sent to JUL to the Android log, while
+ * keeping the format and stack traces of optionally supplied Exceptions. It
+ * further allows to install a {@link DebugLogSettings} class via
+ * {@link #setDebugLogSettings(DebugLogSettings)} that determines whether JUL log messages of
+ * level {@link java.util.logging.Level#FINE} or lower are logged. This gives
+ * the application developer more control over the logged messages, while
+ * allowing a library developer to place debug log messages without risking to
+ * spam the Android log.
+ * </p>
+ * <p>
+ * If there are no {@code DebugLogSettings} configured, then all messages sent
+ * to JUL will be logged.
