--1 The Top-Level English Resource Grammar: Combination Rules
--
-- Aarne Ranta 2002 -- 2003
--
-- This is the English concrete syntax of the multilingual resource
-- grammar. Most of the work is done in the file $syntax.Eng.gf$.
-- However, for the purpose of documentation, we make here explicit the
-- linearization types of each category, so that their structures and
-- dependencies can be seen.
-- Another substantial part are the linearization rules of some
-- structural words.
--
-- The users of the resource grammar should not look at this file for the
-- linearization rules, which are in fact hidden in the document version.
-- They should use $resource.Abs.gf$ to access the syntactic rules.
-- This file can be consulted in those, hopefully rare, occasions in which
-- one has to know how the syntactic categories are
-- implemented. The parameter types are defined in $TypesEng.gf$.
