I recently stumbled upon a collection of propers in French composed by Arnaud Peruta :

There seems to be only the introit and communion, and there is another book with responsorial Psalms.

Has any of you heard of it, or used it ? We're quite poor as far as Propers in the vernacular are concerned here in France, most people basically don't know such a thing as Propers does exist, so any resource in that area seems very welcome to me...
