Smuxi

Neither in Download (HOW TO GET) or the FAQ page there is information what to install if i just want install certain components.
A valid szenario for these would be to install on the server only the engine with its protocolls and not the frontends (at least not the GUI)

After installing smuxi-engine on wheezy from pbo with the following command:

apt-get -t wheezy-backports install smuxi-engine

there are still a plenty of packages difference to the smuxi meta-package:
