[Haskell] I18N, external strings

[Stefan Aeschbacher]

Hi

there is a project for i18n on sourceforge. It contains for example bindings
to the gettext library which could be helpful. I'm not sure though how up to
date this project is (project page looks very empty).
The code is still available in the sourceforge cvs repository:

http://haskell-i18n.cvs.sourceforge.net/haskell-i18n/

Another possibility is to load the lookup tables in the IO monad and then
use a Reader Monad to make your lookup table available in your code.

regards

Stefan
