+# This script is used for testing the ProcessSpawn utility class. This
+# class is used to fork and execute a new process. It also allows for
+# checking the exit code returned when the process terminates.
+# The unit tests execute this script via ProcessSpawn class with
+# different command line parameters to test the class functionality.
+#
+# In particular, they check if the class correctly records the exit code
+# returned. The exit code returned is controlled by the caller. It is
+# possible to explicitly specify the exit code to be returned using
+# the command line options. It is also possible to specify that the
+# exit code is "unique" for the process, so as the test can check
+# that two distinct processes spawned by the same ProcessSpawn
+# object may return different status code. The command line of this
+# script also allows for forcing the process to sleep so as the
+# test has much enough time to verify that the convenience methods
+# checking the state of the process, i.e. process running or not.
+
+# Exit with error if commands exit with non-zero and if undefined variables are
+# used.
