# antlrworks
+ANTLRWorks is a novel grammar development environment for ANTLR v3 grammars
+written by Jean Bovet (with suggested use cases from Terence Parr). It combines
+an excellent grammar-aware editor with an interpreter for rapid prototyping and
+a language-agnostic debugger for isolating grammar errors. ANTLRWorks helps
+eliminate grammar nondeterminisms, one of the most difficult problems for
+beginners and experts alike, by highlighting nondeterministic paths in the
+syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars
+more accessible to the average programmer, improve maintainability and
+readability of grammars by providing excellent grammar navigation and
+refactoring tools, and address the most common questions and problems
+encountered by grammar developers.
