+The following loop translate the above @Tests to a Cureutils::run_tests()
+compatible structure. It converts "OUTPUTS" key into "CMP" + "POST" keys:
+1. Each element in the OUTPUTS key is expected to be an output file
+   from csplit (named xx00, xx01, xx02...)
+   create a "CMP" key for each one, with the output and the filename.
+2. Add a "POST" key, ensuring no extra files have been created.
+   (e.g. if there are 4 expected outputs, xx00 to xx03,
+    ensure xx04 doesn't exist).
+3. Add a "PRE" key, deleting all existing 'xx*' files.
+
+Example:
+
+Before conversion:
+   my @csplit_tests =
+   (
+     ["1", '-z -q - 2 4 6',
+       {IN_PIPE => "1\n2\n3\n4\n5\n6\n"},
+       {OUTPUTS => [ "1\n", "2\n3\n", "4\n5\n", "6\n" ],
+     ]
+   )
+
+After conversion:
+
+   my @csplit_tests =
+   (
+     ["1", '-z -q - 2 4 6',
+       {IN_PIPE => "1\n2\n3\n4\n5\n6\n"},
+       {PRE => sub { unlink glob './xx??' ; }},
+       {CMP => ["1\n",    {'xx00'=> undef}]},
+       {CMP => ["2\n3\n", {'xx01'=> undef}]},
+       {CMP => ["4\n5\n", {'xx02'=> undef}]},
+       {CMP => ["6\n",    {'xx03'=> undef}]},
+       {POST => sub { die "extra file" if -e 'xx04'}},
+     ],
+    );
