Initial import of chimera-1.20 into the packages collection

	Structured peer-to-peer overlays, sometimes also referred to as
	Distributed Hash Tables (DHTs), are scalable network infrastructures
	that support Internet-scale network applications utilizing a
	decentralized resource model.  At their core, these overlays provide
	Key-Based Routing (KBR), where messages addressed to any Key will
	incrementally route towards an overlay node responsible for that key.
	On top of the KBR layer, these overlays can support distributed
	storage using a DHT layer or data location using a DOLR layer.

	On top of these overlays, researchers have proposed numerous
	distributed applications, including distributed storage and backup
	systems, multicast systems, resilient routing networks, distributed
	spam filters, mobility support and anonymous routing networks.

	Chimera is a light-weight C implementation of a "next-generation"
	structured overlay that provides similar functionality as
	prefix-routing protocols Tapestry and Pastry.  Chimera gains
	simplicity and robustness from its use of Pastry's leafsets, and
	efficient routing from Tapestry's locality algorithms.  In addition to
	these properties, Chimera also provides efficient detection of node
	and network failures, and reroutes messages around them to maintain
	connectivity and throughput.
