 Need some external garbage, sorry.
 
-Try to compile this really old code:
-   http://la.buvette.org/devel/libimage/libimage.html
+## do_eff_spass.sh
+
+Script shell permettant (en théorie) de faire un montage
+d'une petite séquence de chacun des effets disponibles
+dans la Fonderie. `singlepass` inside.
 
-Use the code, frtk !
