Command-line utility for generating and checking TTH message digests

tthsum generates and checks TTH checksums root of the THEX hash tree.

The Merkle Hash Tree is a hash construct that exhibits desirable properties for verifying the integrity of files and file subranges in an incremental or out-of-order fashion.

The tool uses the Tiger hash algorithm for both the internal and the leaf nodes, and has an interface identical to md5sum.
