Merci Antalgeek pour ta recherche, j’étais déjà tombé sur ces pages mais vu mon niveau sous Linux, je n’ai pas tout compris. J’ai téléchargé le premier ficher, c’est une archive gz dans laquelle il y a un fichier mais je ne sais pas quoi en faire…
On dirait un fichier résultant d’un comparaison entre deux fichiers, il ya des paragraphes du type :
diff -Nuar sane-backends-1.0.7-beta2/backend/Makefile.in sane-backends-1.0.7-beta2.mod/backend/Makefile.in

et des paragraphes de code :
