This projects builds an ant task used by the NetBeans IDE when refreshing the generated parser for the PHP editor module.
The core problem this module solves is, that the grammar yields a java file and also a classfile that can't be used by the JVM/compiled by javac. In its unprocessed form the parser exceeds 100_000 lines. This code breaks it down into smaller parts that can be compiled and loaded individually.
This code is from the original Mercurial NetBeans repository.
