      <title>Introduction</title>
  <para>
	RapidIO is a high speed switched fabric interconnect with
	features aimed at the embedded market.  RapidIO provides
	support for memory-mapped I/O as well as message-based
	transactions over the switched fabric network. RapidIO has
	a standardized discovery mechanism not unlike the PCI bus
	standard that allows simple detection of devices in a
	network.
  </para>
  <para>
  	This documentation is provided for developers intending
	to support RapidIO on new architectures, write new drivers,
	or to understand the subsystem internals.
