One of the main ideas of GF is the use of libraries in grammar writing, in a way familiar from software engineering. In this way, large grammars can be built in cooperation, and old grammars or parts of them can be reused in new grammars. The slides Grammars as Software Libraries give some introduction to this idea.

## The resource grammar library

This library covers basic linguistic structures of different languages.

Version 1.1 released 22 December 2006 (enhanced version of 1.0). Covers Danish, English, Finnish, French, German, Italian, Norwegian, Russian, Spanish, and Swedish.

Two older versions are also available: Version 0.9 and Version 0.6.

## The prelude library

The prelude library gives utility functions for different GF applications:

Precedence. Utilities for formal languages: precedence levels, associatives, infixes.

Predef. Type signatures of predefined (hard-coded) functions.

Prelude. Generic utilities for strings, tables, records, booleans.
