Stratego/XT is a development environment for creating stand-alone transformation systems. It combines Stratego, a language for implementing transformations based on the paradigm of programmable rewriting strategies, with XT, a collection of reusable components and tools for the development of transformation systems. In general, Stratego/XT is intended for the analysis, manipulation, and generation of programs, though its features make it useful for transforming any structured documents. In practice, it has been used to build many types of transformation systems including compilers, interpreters, static analyzers, domain-specific optimizers, code generators, source code refactorers, documentation generators, and document transformers.
