Each script can use a specific parameters pannel, written in Qml language, to set up options and form a valid command line.<br>
Open "View sources pannel" <img src="../../icons/view-source.png" width=20><br>
Button "Pannel source" <img src="../../icons/view-code.png" width=20> display current
pannel parameters file <i>Scripts.qml</i>.
<h4>Add a customized script pannel :</h4>

      params: "Hello.qml"
      tty: true
      help: "Run script \"hello.sh\"."
  }
</pre>
