+       help
+         This library calculates only CRC16 (16-bit codes) and the
+         only supported variant at the moment is CRC-CCITT (XModem).
+         CRC is a way of detecting accidental changes in data storage
+         or transmission. There are many variants of CRC and CRC16,
+         in particular.
