+# 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
+
+ME_=`expr "./$0" : '.*/\(.*\)$'`
+
+# We use a trap below for cleanup. This requires us to go through
+# hoops to get the right exit status transported through the handler.
+# So use 'Exit STATUS' instead of 'exit STATUS' inside of the tests.
+# Turn off errexit here so that we don't trip the bug with OSF1/Tru64
+# sh inside this function.
+Exit () { set +e; (exit $1); exit $1; }

+# Override by defining to say, 9, in init.cfg, and putting say,
+# export ...ENVVAR_SETTINGS...; $(SHELL) 9>&2
+# in the definition of TESTS_ENVIRONMENT in your tests/Makefile.am file.
+# This is useful when using automake's parallel tests mode, to print
+# the reason for skip/failure to console, rather than to the .log files.
