All the different routes

This is timely for a question I have -- but unfortunately, it doesn't answer it.

First a couple of sentences of background. My wife and I are Canadians planning to walk our first Camino starting in September. At the moment, we are in Angers, France, the western part of the Loire Valley and we are doing some longish walks while we are here just for the pleasure of walking but also as practice for our Camino. A couple of days ago, we were walking along the banks of the Maine River near where it joins the Loire and we were excited to find that our path was joined by a waymarked Camino path. The markings were unmistakable and quite new, sturdy-looking yellow scallop shells marking the path. It gave us a real thrill to see them.

So, finally, my Question: I wonder what Camino route this is (we are well west of Tours, I would guess at least 60 miles) and who is doing the waymaking? I assume it is a French association that is expanding their repertoire of marked routes but I wonder if it is newly marked "traditional" route or just another way of taking advantage of the system of GRs in France.
