# Purpose: This script is needed to start the routing manager daemon and the
# clients with one command. This is necessary as ctest - which is used to run
# the tests - isn't able to start multiple binaries for one testcase. Therefore
# the testcase simply executes this script. This script then runs the routing
# manager daemon and the clients and checks if all of them exit successfully.
