+ * Support routines to send messages to the Android log buffer,
+ * which can later be accessed through the `logcat` utility.
+ *
+ * Each log message must have
+ *   - a priority
+ *   - a log tag
+ *   - some text
+ *
+ * The tag normally corresponds to the component that emits the log message,
+ * and should be reasonably small.
+ *
+ * Log message text may be truncated to less than an implementation-specific
+ * limit (1023 bytes).
+ *
+ * Note that a newline character ("\n") will be appended automatically to your
+ * log message, if not already there. It is not possible to send several
+ * messages and have them appear on a single line in logcat.
+ *
+ * Please use logging in moderation:
+ *
+ *  - Sending log messages eats CPU and slow down your application and the
+ *    system.
+ *
+ *  - The circular log buffer is pretty small, so sending many messages
+ *    will hide other important log messages.
+ *
+ *  - In release builds, only send log messages to account for exceptional
+ *    conditions.
