+A resource grammar is a grammar built on linguistic grounds,

+The GF resource grammar library contains resource grammars for

+However, to give a flavour of both using and writing resource grammars,
+we have created a miniature resource, which resides in the
+subdirectory [``resource`` resource]. Its API consists of the following
+modules:
+- [Syntax resource/Syntax.gf]: syntactic structures, language-independent
+- [LexEng resource/LexEng.gf]: lexical paradigms, English
+- [LexIta resource/LexIta.gf]: lexical paradigms, Italian
+
+
+Only these three modules should be ``open``ed in applications.
+The implementations of the resource are given in the following four modules:
+- [MorphoEng resource/MorphoEng.gf],
+  [MorphoIta resource/MorphoIta.gf]: low-level morphology
+- {SyntaxEng resource/SyntaxEng.gf].
+  [SyntaxIta resource/SyntaxIta.gf]: definitions of syntactic structures

+An example use of the resource resides in the
