+Python module.  And, once loaded, they have different methods for accessing
+individual images, looping through the images in bulk, accessing a specific
+range, or dealing with multidimensional files.  PIMS can do all of these using
+a consistent interface, handling the differences between different inputs
+invisibly.")
