The directory examples/workflow includes some examples of workflows. You can find a simple workflow (see Figure 14.1) in the file xml/scalar.xml and you can test it with the following command:
./scalar_client local_client.cfg scalar.xml
You need to have a running DIET platform with the needed services. You can launch a single SeD (scalar_server) that includes all the needed services. (read Chapter 5 for more details).
