Translation of the Gentle Introduction to Haskell 98
by Gorgonite 01 May '07

01 May '07

Hello, I don't know if there are French-speaking people reading this mailing-list, but we at haskell-fr have some great news today ! We didn't find any French translation of the "Gentle Introduction to Haskell" (version 98), thus we decide to write it. Today, I would like to announce that we have completed a translation into French, that it can be read by following the link : http://gorgonite.developpez.com/livres/traductions/haskell/gentle-haskell/ It is currently available as a set of HTML pages. We are also putting into the "official format" with *.verb files. Hopefully you will soon be able to download that version as well. Please send your comments and suggestions to the French Haskell mailing list haskell-fr(a)haskell.org Best regards,
