Instead of just giving an explicit list of languages to compile, you can
now also add and remove languages from the default list by using langs=+...
or langs=-...
Examples:
cabal build langs=Eng,Swe,Ger -- as before, compile the given 3 langs
cabal build langs=-Fin -- use default languages, but omit Fin
cabal build langs=+Urd -- use default languages + Urd
("cabal build ..." is the same as "runhaskell Setup.hs build ...")
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)
