If you are interested only in running the head-corner parser on the
Alvey NL Tools grammar, then you are referred to the Hdrug homepage. Hdrug is an
environment for the development of logic grammars and related
parsers and generators. The Alvey NL Tools grammar with a number
of parsers is one of the example applications shipped with
Hdrug. Here is a screen dump.
