Lexical analyser and parser for the Ada language

OpenToken is a facility for performing token analysis and parsing within the Ada language. It is designed to provide all the functionality of a traditional lexical analyzer/parser generator, such as lex/yacc. But due to the magic of inheritance and runtime polymorphism it is implemented entirely in Ada as withed-in code. No precompilation step is required, and no messy tool-generated source code is created. The tradeoff is that the grammar is generated at runtime.
