This document provides a quick overview of some Mac OS X specific features in
the Python distribution.

* ``32-bit``: ``ppc``, ``i386``
* ``3-way``: ``i386``, ``x86_64``, ``ppc``
* 10.7 and 10.8 SDKs with Xcode 4 support ``intel`` only
-The makefile for a framework build will also install ``python3.3-32``

binaries when the universal architecture includes at least one 32-bit
architecture (that is, for all flavors but ``64-bit``).
not automatically carry through to subprocesses launched by programs and tests

A second reason for using frameworks is that they put Python-related items in
only two places: "/Library/Framework/Python.framework" and
-"/Applications/Python <VERSION>" where ``<VERSION>`` can be e.g. "3.3",
+"/Applications/Python <VERSION>" where ``<VERSION>`` can be e.g. "3.4",
"2.7", etc. This simplifies matters for users installing
Python from a binary distribution if they want to get rid of it again. Moreover,
due to the way frameworks work, a user without admin privileges can install a

+- Issue #14499: Fix several problems with OS X universal build support:
+ 1. ppc arch detection for extension module builds broke with Xcode 5
+ 2. ppc arch detection in configure did not work on OS X 10.4
+ 3. -sysroot and -arch flags were unnecessarily duplicated
+ 4. there was no obvious way to configure an intel-32 only build.
