+Date: June 2011
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: The integer value of this attribute ranges from 0-4.
+ When read, this attribute returns the number of the actual
+ profile. This value is persistent, so its equivalent to the
+ profile that's active when the device is powered on next time.
+ When written, this file sets the number of the startup profile
+ and the device activates this profile immediately.
