+       help
+         Since sprintf() can overflow its buffer, it is common to use
+         snprintf() instead, which knows the buffer size and can avoid
+         overflow. However, this does increase code size slightly (for
+         Thumb-2, about 420 bytes). Enable this option for safety when
