Commercial Pilot Glider license in EU

Is there a Commercial Pilots License-Glider in EU ?

I looked around in the CAA, JAA and EASA websites, but could't really find
this information.

In some coutries a CFIG (Instructor's) license gives you the right to work
and get paid as an instructor, even though you may not have a Commercial
Pilot's license.
In other countries, the CP is a pre-requisite for a CFIG, which is the case
in the US, for instance.
I'd like to know how it is in EU.
