+#   This is useful e.g. for programs like du that produce output that
+#   varies a lot from system.  E.g., an empty file may consume zero file
+#   blocks, or more, depending on the OS and on the file system type.
+# {ERR_SUBST => 's/variable_output/expected_output/'}
+#   Transform actual stderr output before comparing it against expected.
+#   This is useful when verifying that we get a meaningful diagnostic.
+#   For example, in rm/fail-2eperm, we have to account for three different
+#   diagnostics: Operation not permitted, Not owner, and Permission denied.
+# {EXIT => N} expect exit status of cmd to be N
+# {ENV => 'VAR=val ...'}
+#   Prepend 'VAR=val ...' to the command that we execute via 'system'.
+# {ENV_DEL => 'VAR'}
+#   Remove VAR from the environment just before running the corresponding
+#   command, and restore any value just afterwards.
+#
+# There may be many input file specs.  File names from the input specs
+# are concatenated in order on the command line.
+# There may be at most one of the OUT-, ERR-, and EXIT-keyed specs.
+# If the OUT-(or ERR)-keyed hash ref is omitted, then expect no output
+#   on stdout (or stderr).

+# Using this file in a test
+# =========================
+#
+# The typical skeleton of a test looks like this:
+#
+#   #!/bin/sh
+#   . "${srcdir=.}/init.sh"; path_prepend_ .
+#   Execute some commands.
+#   Note that these commands are executed in a subdirectory, therefore you
+#   need to prepend "../" to relative filenames in the build directory.
+#   Note that the "path_prepend_ ." is useful only if the body of your
+#   test invokes programs residing in the initial directory.
+#   For example, if the programs you want to test are in src/, and this test
+#   script is named tests/test-1, then you would use "path_prepend_ ../src",
+#   or perhaps export PATH='$(abs_top_builddir)/src$(PATH_SEPARATOR)'"$$PATH"
+#   to all tests via automake's TESTS_ENVIRONMENT.
+#   Set the exit code 0 for success, 77 for skipped, or 1 or other for failure.
+#   Use the skip_ and fail_ functions to print a diagnostic and then exit
+#   with the corresponding exit code.
+#   Exit $?
+
+# Executing a test that uses this file
+# ====================================
+#
+# Running a single test:
+#   $ make check TESTS=test-foo.sh

+# Running a single test, with verbose output:
+#   $ make check TESTS=test-foo.sh VERBOSE=yes

+#
+# Running a single test, with single-stepping:
+#   1. Go into a sub-shell:
+#   $ bash
+#   2. Set relevant environment variables from TESTS_ENVIRONMENT in the
+#      Makefile:
+#   $ export srcdir=../../tests # this is an example
+#   3. Execute the commands from the test, copy&pasting them one by one:
+#   $ . "$srcdir/init.sh"; path_prepend_ .
+#   ...
+#   4. Finally
+#   $ exit

+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"},
