+          The AMD fork of the BLIS library, with attribute
+          <literal>amd-blis</literal>, extends BLIS with optimizations for
+          modern AMD CPUs. The changes are usually submitted to
+          the upstream BLIS project after some time. However, AMD BLIS
+          typically provides some performance improvements on AMD Zen CPUs.
+          The complementary AMD LIBFLAME library, with attribute
+          <literal>amd-libflame</literal>, provides a LAPACK implementation.
