+=item Legacy implementations
+
+Legacy implementations will simply display the main name of the
+algorithm on a line of its own, or in the form C<<foo > bar>> to show

+
+=item Provided implementations
+
+Implementations from a provider are displayed like this if the
+implementation is labeled with a single name:
+
+ foo @ bar
+
+or like this if it's labeled with multiple names:
+
+ { foo1, foo2 } @bar

+In both cases, C<bar> is the name of the provider.
