+=== Service scripts ===
+  * Through the aliases **''watch_hv''** and **''watch_apfel''**, it is possible to see the output of the respective servers. The log files to which the servers write to are:
+  /home/pi/apfel_dev/hv_control/hvlog.{out,err}
+  /home/pi/apfel_dev/apfel_interface/apfellog.{out,err}
+  * The servers can be killed and restarted through the aliases **''start_hv''** and **''start_apfel''**.
+  * Without arguments, the scripts check if there are running server processes and if so exit with an output like:
+  n. of server processess: 2
+  n. of watch processess: 2
+  processes running, kill first
+  * To kill the processes, call the aliases with the argument ''-kill'' (e.g. ''start_hv -kill'').
+  * **Only for ''start_apfel''**, it is possible to start the server with the verbose flag set by invoking the alias with ''start_apfel -v''.
- Note: for now use the pi only locally with keyboard and monitor...
