+# 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
+
