Developer mode is enough -- when developer mode is enabled
developers can install software to have the same credentials
as ovi store provides -- without developer mode users are
restricted to 'unknown origin' credentials if software is not
installed from ovi store.

But, as the vpnc.sh is the one having credentials given
by _aegis the vpnc can be run via command line something
like the following way:

(cd /opt/vpn9c/bin && exec ./vpnc.sh ) < your-config-file.

I'll test this configuration and add note about it for those
who want to use it this way.

Alternatively, one can pick the vpnc binary and _aegis file
from the .deb and build new package for their own purposes

Thank you for all of you running this software,

Tomi
