+Customizung the directory structure

+The ``var/`` directory contains three directories you can fill with
+your own content.
+
+================ ==================
+Menu item ``var/`` Directory
+================ ==================
+Internet Radio ``internetradio``
+Podcasts ``podcasts``
+My Noxon ``mynoxon``
+================ ==================
+
+You can put folders and files into this directories.
+
+The ``internetradio`` directory is hard-coded to display the contents
+of a MediaTomb UPnP server.

+want this.

+File types
+==========
+Directory
+ A directory is browsable by your Noxon radio
+``.sh`` file
+ Shell script which is shown as directory and which gets executed
+ when navigating into it.
+ Output is shown as it is for ``.txt`` files.
+
+ I use it to control my house's heating system from the radio.
+``.auto.sh``
+ Shell script which gets executed when browsing the folder.
+ The output is integrated into the directory listing with the same
+ rules as for ``.txt`` files.
+
+ You can use this to show the current time within the directory listing.
