public class DifferentSelector extends MappingSelector
This is a useful selector to work with programs and tasks that don't handle dependency checking properly; Even if a predecessor task always creates its output files, followup tasks can be driven off copies made with a different selector, so their dependencies are driven on the absolute state of the files, not a timestamp.
Clearly, however, bulk file comparisons is inefficient; anything that can use timestamps is to be preferred. If this selector must be used, use it over as few files as possible, perhaps following it with an <uptodate;> to keep the descendent routines conditional.
