Description: semantic web reasoning engine
 Euler Yet another proof Engine (EYE) is a reasoning engine
 supporting the Semantic Web layers.
 It performs semibackward chaining and it supports Euler paths.
 Via N3 it is interoperable with Cwm.
 .
 Semibackward chaining
 is backward chaining for rules using <= in N3
 and forward chaining for rules using => in N3.
 This can be seen in EYE Reasoning.
 .
 Euler paths are roughly "don't step in your own steps"
 which is inspired by what Leonhard Euler discovered in 1736
 for the Königsberg Bridge Problem.
 EYE sees the rule P => C as P & NOT(C) => C.
 .
 Notation3 (N3) is a shorthand non-XML serialization
 of Resource Description Framework (RDF) models,
 designed with human-readability in mind:
 N3 is much more compact and readable than XML RDF notation.
 .
 Resource Description Framework (RDF) is a standard model
 for data interchange on the Web.
