The pipeline recipes can executed in the following way:
1) Create a new directory somewhere and let the environment
variable RECIPE_SOF_PATH point to it
2) For recipe <recipe>, create a .sof-file 
$RECIPE_SOF_PATH/<recipe>.sof - the fits files listed in
this sof should have a full path.
3) make check
   will then, after doing some error testing on the recipes,
   execute them on the specified sofs.
