] Purple is a small suite of quickly hacked tools inspired
] by Doug Engelbart's attempt to bootstrap the addressing
] features of his Augment system onto HTML pages. Its
] purpose is simple: produce HTML documents that can be
] addressed at the paragraph level. It does this by
] automatically creating name anchors with static and
] hierarchical addresses at the beginning of each text
] node, and by displaying these addresses as links at the
] end of each text node.
