+3. How do I specify binary universal wheels
+-------------------------------------------
+
+Binary wheels can also be universal. The platform tag name used to identify
+universal binary wheels differs from the naming scheme used when configuring a
+universal build with ``--with-universal-archs``. See the Python Packaging User
