How to use \guilsinglleft and \guilsinglright in csquotes

I was reading Jan Tschichold's The Form of the Book and he suggest to use

‹ [\guilsinglleft] and › [\guilsinglright]

instead of « » for the outer quotation mark. So, I wonder how to do it, provided that Biblatex produces the article entry (and other entries as well) with «guillemots».

The output should look something like this:

‹Here is a quote «and a quote within». Done!›

The code should be

\enquote{Here is a quote \enquote{and a quote within}. Done!}
