Coco/r is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. the scanner works as a deterministic finite automaton. the parser uses recursive descent. ll(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. thus the class of accepted grammars is ll(k) for an arbitrary k.
