Hdrug is designed to be as flexible and extendible as possible. This is illustrated by the fact that Hdrug has been used both for the development of practical real-time systems, but also as a tool to experiment with new theoretical notions and alternative processing strategies. Grammatical formalisms that have been used range from context-free grammars to concatenative feature-based grammars (such as the grammars written for ALE) and non-concatenative grammars such as Tree Adjoining Grammars.
