+# FloatImg4PythonBinding
+
+Un fork de la galactique bibliothèque FloatImg de tTh, réaménagé pour permettre une utilisation depuis Python avec l'embryonnaire binding https://git.tetalab.org/Mutah/python-FloatImg/ (seulement sur la branche develop pour le moment)
+
+Pas de révolution mais :
+
+ - production d'une bibliothèque partagée
+ - arborescence remanié : les meubles ont changés de place : les sources sont dans `src`, les expérimentations dans `extra` et les binaires sont produits dans `build`
+ - build system : un Makefile racine avec des cibles générales : `all` pour tout builder, `lib` pour la bibliothèque de base, `funcs`
