What is ANTLR 3?
To be written. Volunteers?
ANTLR v3 is the latest evolution of the PCCTS and ANTLR toolkits used for developing language processing tools. ANTLR (ANother Tool for Language Recognition) provides a framework for the generation of recognizers, compilers, and translators from grammatical descriptions. The generated code can be Java, C#, Objective-C or C. The grammatical descriptions can optionally include action code written in the target language (i.e. Java, C#, Objective-C, C etc). In the future, support for additional languages such as C++, Ruby and Perl6 is expected.
What does ANTLR 3 do?

Given grammatical descriptions of a langauge, ANTLR v3 can be used to generate source code for various tools for processing input in that language.
Why should I use ANTLR 3?

ANTLR v3's improved analysis engine, it's significantly enhanced parsing strength via LL(*) parsing with arbitrary lookahead and it's vastly improved tree construction rewrite rules would save you time and money if you need to construct language processing tools.
