-"""XTEA Block Encryption Algorithm
+"""TEA, XTEA and XXTEA Block Encryption Algorithms
 
-This module provides a Python implementation of the XTEA block encryption
-algorithm (http://www.cix.co.uk/~klockstone/xtea.pdf). 
-
-The module implements the basic XTEA block encryption algortithm
-(`xtea_encrypt`/`xtea_decrypt`) and also provides a higher level `crypt`
-function which symmetrically encrypts/decrypts a variable length string using
-XTEA in OFB mode as a key generator. The `crypt` function does not use
-`xtea_decrypt` which is provided for completeness only (but can be used
-to support other stream modes - eg CBC/CFB).
