+# This script runs all the unit tests that can be found, and generates a nice
+# report of the tests.
+#
+### Sample usage:
+#
+# Run all tests for all shells.
+# $ ./test_runner
+#
+# Run all tests for single shell.
+# $ ./test_runner -s /bin/bash
+#
+# Run single test for all shells.
+# $ ./test_runner -t shunit_asserts_test.sh
+#
+# Run single test for single shell.
+# $ ./test_runner -s /bin/bash -t shunit_asserts_test.sh
+#
+### ShellCheck (http://www.shellcheck.net/)
+# Disable source following.
+#   shellcheck disable=SC1090,SC1091
+# expr may be antiquated, but it is the only solution in some cases.
+#   shellcheck disable=SC2003
+# $() are not fully portable (POSIX != portable).
+#   shellcheck disable=SC2006
+
+# Return if test_runner already loaded.
