 \section{New Control Interface}
+The MVD user software serves three main purposes: Editing the sensor and electronics settings,
+coordination of data taking, and continuous monitoring of sensor parameters (power consumption,
+temperature, etc). In order to make the functionality accessible to non-hardware-experts,
+the development of an elaborate graphical user interface has been initiated.
+
+The user software consists of two parts: a back end software suite implemented in perl and a
+web interface front end written in HTML/CSS/Javascript. Though this approach appears intricate,
+the strict separation of front end and back end has substantial advantages:
+The DAQ is inherently remotely accessible to multiple users on different machines, while
+the design flexibilty of HTML and CSS helps providing a clear structure and a good overview of
+the functionality. Furthermore the back end scripts can be also used from the command line or 
+shell scripts to automate complex configure and/or measurement tasks.
+
+All configuration files are stored in the strictly hierarchical but human readable XML format
+in order to keep the system transparent to the developer.
