/**************************** roothelper.h *****************************

Code for the root helper registered on DBus.  When registered the CMST
provisioning editor will communicate with object using signals.  As the
name implies roothelper is run as the root user, since we need to read
and write to /var/lib/connman. This program is started by DBus and the
configuration files necessary to make that happen are in the system dir.
