	The libSTARK library implements scalable and transparent argument of
	knowledge (STARK) systems.  These systems can be executed with, or
	without, zero knowledge (ZK), and may be designed as either
	interactive or non-interactive protocols.  The theoretical
	constructions which this library implements are described in detail in
	the zk-STARK paper:

	Scalable, transparent, and post-quantum secure computational integrity
