+ *   - some text
+ *
+ * The tag normally corresponds to the component that emits the log message,

+ * Note that a newline character ("\n") will be appended automatically to your

+ * and have them appear on a single line in logcat.
+ *
+ * PLEASE USE LOGS WITH MODERATION:
+ *
+ *  - Sending log messages eats CPU and slow down your application and the
+ *    system.
+ *
+ *  - The circular log buffer is pretty small (<64KB), sending many messages
+ *    might push off other important log messages from the rest of the system.
