The development of a natural language system usually requires frequent changes to the grammar used. It is then very useful to be able to define and modify the grammar rules easily, without having to tamper with the parsing program. The ARBUS system was designed to help develop grammars for natural language processing. With this system one can build, display, test, modify and file a grammar interactively in a very convenient way. This was achieved by packaging a parser and a grammar editor with an elaborate interface which isolates the user from implementation details and guides him as much as possible.
