+# Using this file in a test
+# =========================
+#
+# The typical skeleton of a test looks like this:
+#
+#   #!/bin/sh
+#   : ${srcdir=.}
+#   . "$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.
+#   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
+
+# We require $(...) support unconditionally.
+# We require a few additional shell features only when $EXEEXT is nonempty,
+# in order to support automatic $EXEEXT emulation:
+# - hyphen-containing alias names
+# - we prefer to use ${var#...} substitution, rather than having
+#   to work around lack of support for that feature.
+# The following code attempts to find a shell with support for these features
+# and re-exec's it.  If not, it skips the current test.
