This is just to make it easier to tell who has the latest version at the summer school. There has been some bug fixes in gf itself and some significant additions to the RGL since 3.2 was released. Also explicitly require Alex 2.x. The recently released Alex 3.0 has backwards incompatible changes and does not work. GF/Grammar/Lexer.x should probably be modified to support both Alex 2.x and Alex 3.0...
DESCRIPTION
The Grammatical Framework (=GF) is a grammar formalism based on type theory.
It consists of
* a special-purpose programming language
* a compiler of the language
* a generic grammar processor
The compiler reads GF grammars from user-provided files, and the
generic grammar processor performs various tasks with the grammars:
* generation
* parsing
* translation
* type checking
* computation
* paraphrasing
* random generation
* syntax editing
GF particularly addresses four aspects of grammars:
* multilinguality (parallel grammars for different languages)
* semantics (semantic conditions of well-formedness, semantic
properties of expressions)
* grammar engineering (modularity, abstractions, libraries)
* embeddability in programs written in other languages (C,C++,
Haskell, Java, JavaScript)
