     <ol>
     <li> If there is no 'other' file, it's different.
     <li> Files with different lengths are different.
     <li> If <tt>ignoreFileTimes</tt> is turned off, then differing file
     timestamps will cause files to be regarded as different.

     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 just
-    a timestamp. For example: anything fetched from a web site, or the output of
-    some program. To reduce the amount of checking, when using this task inside
-    a <code>&lt;copy&gt;</code> task, set the <tt>preservelastmodified</tt> to propagate the timestamp
-    from source file to destintaion file.

     to define the location of the file to be compared against. If no
