To acquire knowledge that is fit for a specific purpose, it is very desirable to have a structured, declarative expression of the knowledge that is needed. This paper introduces a stand-alone knowledge acquisition tool, called COCKATOO (Constraint-Capable Knowledge Acquisition Tool), which uses constraint technology to specify the knowledge it requires. The language in which these speci-fications are given is based on the meta-language notation of context-free grammars. However, we also took the op-portunity to build a tool that is both more flexible and pow-erful by augmenting context-free grammars with the ex-pressiveness of constraints. COCKATOO was imple-mented using the SCREAMER+ declarative constraints package.
