+To build a universal binary that includes a 64-bit architecture, you must build

+(that is, for all flavours but ``64-bit``).
+
+Running a specific archicture
+.............................
+
+You can run code using a specific architecture using the ``arch`` command::
+
+   $ arch -i386 python
+
+Or to explicitly run in 32-bit mode, regardless of the machine hardware::
+
+   $ arch -i386 -ppc python
+
+NOTE: When you're using a framework install of Python this requires at least
+Python 2.7 or 3.2, in earlier versions the python (and pythonw) commands are
+wrapper tools that execute the real interpreter without ensuring that the
+real interpreter runs with the same architecture.
