Dragon produces a consequent, object-oriented, integrated scanner and parser solution and scales for very large grammar definitions. It provides LR(1) and LALR grammar analysis methods and combines the lexical and syntactical analysis and the corresponding code generation. Either C++ or Java code can be generated. The resulting parser code is readable and clean, and can easily be integrated into any C++ or Java application.

Autooconf cleanup, a change to lfcbase, and an upgrade to the GPLv3.
