102<P>
103This selector selects files against a mapped set of target files, selecting
104 all those files which are different.
105 Files with different lengths are deemed different
106 automatically
107 Files with identical timestamps are viewed as matching by
108 default, unless you specify otherwise.
109 Contents are compared if the lengths are the same
110 and the timestamps are ignored or the same,
111 except if you decide to ignore contents to gain speed.
112 <p>
113 This is a useful selector to work with programs and tasks that don't handle
114 dependency checking properly; Even if a predecessor task always creates its
115 output files, followup tasks can be driven off copies made with a different
116 selector, so their dependencies are driven on the absolute state of the
117 files, not a timestamp.
118 <p>
119 Clearly, however, bulk file comparisons is inefficient; anything that can
120 use timestamps is to be preferred. If this selector must be used, use it
121 over as few files as possible, perhaps following it with an &lt;uptodate;&gt
122 to keep the descendent routines conditional.
