Description:	Ox generalizes the function of Yacc in the way that attribute grammars generalize context-free grammars. Ordinary Yacc and Lex specifications may be augmented with definitions of synthesized and inherited attributes written in C syntax. Ox checks these specifications for consistency and completeness, and generates from them a program that builds and decorates attributed parse trees. Ox accepts a most general class of attribute grammars. The user may specify postdecoration traversals for easy ordering of side effects such as code generation. Ox handles the tedious and error-prone details of writing code for parse-tree management, so its use eases problems of security and maintainability associated with that aspect of translator development. Ox is a preprocessor, and extends the syntax and semantics of Yacc, Lex, and C.
Reference:	Most compiler textbooks have descriptions of attribute grammars.
