The programming language OPTRAN has been developed as a tool for the description of program transformations. The intermediate form of programs to be transformed is the attributed program tree, as existing in many automatically generated multi-pass compilers, e.g. MUG2. OPTRAN is based on attributed transformational grammars, but extends these to achieve more compact descriptions, more efficient transformers, and an adequate cooperation of several transformation passes.
