(description "Hashcash is a proof-of-work algorithm, which has been used
as a denial-of-service countermeasure technique in a number of systems.
A hashcash stamp constitutes a proof-of-work which takes a parametrizable
amount of work to compute for the sender. The recipient can verify received
hashcash stamps efficiently.
This package contains a command-line tool for computing and verifying hashcash
stamps.")
