-27 June 2008: release of GF 3.0 and a new web page; the old web page is
-<A HREF="index-2.html">here</A>.

-<H2>What is GF</H2>
-<P>
-GF, Grammatical Framework, is a programming language for
-<B>multilingual grammar applications</B>. It is
-</P>
-<UL>
-<LI>a <B>special-purpose language for grammars</B>, like YACC, Bison, Happy, BNFC
-<LI>a <B>functional language</B>, like Haskell, Lisp, OCaml, Scheme, SML
-<LI>a <B>natural language processing framework</B>, like LKB, XLE, Regulus
-<LI>a <B>categorial grammar formalism</B>, like ACG, CCG
-<LI>a <B>logical framework</B>, like Agda, Coq, Isabelle
-</UL>
-
-<P>
-Don't worry if you don't know most of the references above - but if you do know at
-least one, it may help you to get a first idea of what GF is.
-</P>
-<H2>Applications</H2>
-<P>
-GF can be used for building
-</P>
-<UL>
-<LI>[text translators ]
-<LI>[speech translators ]
-<LI>[natural-language interfaces ]
-<LI>[multilingual web pages ]
-<LI>[multilingual authoring systems ]
-<LI>[dialogue systems ]
-<LI>[language training systems ]
-<LI>[natural language resources ]
-</UL>
-
-<H2>Availability</H2>
-<P>
-GF is <B>open-source</B>, licensed under [GPL ] (the program) and [LGPL ] (the libraries). It
-is available for
-</P>
-<UL>
-<LI>[Linux ]
-<LI>[Mac OS X ]
-<LI>[Windows ]
-<LI>via compilation to [JavaScript ], almost any platform that has a web browser
-</UL>
-
-<H2>Projects</H2>
-<P>
-GF was born in 1998 at Xerox Research Centre Europe, Grenoble in the project
-Multilingual Document Authoring. At Xerox, it was used for prototypes including
-a restaurant phrase book in 6 languages,
-a database query system in 7 languages,
-a formalization of an alarm system instructions with translations to 5 languages, and
-an authoring system for medical drug descriptions in 2 languages.
-</P>
-<P>
-Later projects using GF and involving third parties include, in chronological order,
-</P>
-<UL>
-<LI>GF-Alfa: natural language interface to formal proofs
-<LI>GF-KeY: authoring and translation of software specifications
-<LI>TALK: multilingual and multimodal spoken dialogue systems
-<LI>WebALT: multilingual generation of mathematical exercises (commercial project)
-<LI>MultiWiki: multilingual Wiki for restaurant reviews
-<LI>SALDO: Swedish morphological dictionary based on tools developed for GF
-</UL>
-
-<P>
-Academically, GF has been used in four [PhD theses ], and resulted in around
-fifty [scientific publications ].
-</P>
-<H2>Programming in GF</H2>
-<P>
-GF is easy to learn by following the <A HREF="doc/gf-tutorial.html">tutorial</A>. You can write your
-first translator in 15 minutes.
-</P>
-<P>
-GF has an interactive command interpreter, as well as a batch compiler. Grammars can be
-compiled to parser and translator code in many different formats. These components can
-then be embedded in applications written in other programming languages. The formats
-currently supported are:
-</P>
-<UL>
-<LI>Haskell
-<LI>Java
-<LI>JavaScript
-<LI>Prolog
-<LI>Speech recognition: HTK/ATK, Nuance, JSGF
-</UL>
-
-<P>
-The GF programming language is high-level and advanced, featuring
-</P>
-<UL>
-<LI>static type checking
-<LI>higher-order functions
-<LI>dependent types
-<LI>pattern matching with data constructors and regular expressions
-<LI>module system with multiple inheritance and parametrized modules
-</UL>
-
-<H2>Libraries</H2>
-<P>
-Libraries are at the heart of modern software engineering. In natural language
-applications, libraries are a way to cope with thousands of details involved in
-syntax, lexicon, and inflection. The <A HREF="lib/">GF resource grammar library</A> has
-support for an increasing number of languages, currently including
-</P>
-<OL>
-<LI>Arabic (partial)
-<LI>Bulgarian
-<LI>Catalan (partial)
-<LI>Danish
-<LI>English
-<LI>Finnish
-<LI>French
-<LI>German
-<LI>Hindi/Urdu (fragments)
-<LI><A HREF="http://www.interlingua.com/">Interlingua</A>
-<LI>Italian
-<LI>Norwegian bokmål
-<LI>Russian
-<LI>Spanish
-<LI>Swedish
-<LI>Thai (fragments)
-</OL>
-
-<P>
-Adding a language to the resource library takes 3 to 9
-months - <A HREF="doc/projects.html">contributions</A>
-are welcome!
