Download the Native Client SDK
==============================
-To build Native Client modules, you must download and install the Native
-Client Software Development Kit (SDK). This page provides an overview
-of the Native Client SDK, and instructions for how to download and
-install the SDK.

Overview
--------
-The Native Client SDK includes the following:
-
-support for multiple Pepper versions
- The SDK contains **bundles** that let you compile Native Client modules
- using different versions of the
- :ref:`link_pepper` (e.g., Pepper 31 or Pepper Canary). Review the
- :doc:`Release Notes <release-notes>` for a description of the new features
- included in each Pepper version to help you decide which bundle to
- use to develop your application. In general, Native Client modules
- compiled using a particular Pepper version will work in
- corresponding versions of Chrome and higher. For example, a module
- compiled using the Pepper 31 bundle will work in Chrome 31 and
- higher.
-
-update utility
- The ``naclsdk`` utility (``naclsdk.bat`` on Windows) lets you download new
- bundles that are available, as well as new versions of existing bundles.
-
-toolchains
- Each platform includes three toolchains: one for compiling
- Portable Native Client (PNaCl) applications, one for compiling
- architecture-specific Native Client applications with newlib, and
- one for compiling architecture-specific Native Client applications with glibc.
- Newlib and glibc are two different implementations
- of the C standard library. All three toolchains contain
- Native Client-compatible versions of standard compilers, linkers,
- and other tools. See :doc:`NaCl and PNaCl </nacl-and-pnacl>` to help
- you choose the right toolchain.
-
-examples
- Each example in the SDK includes C or C++ source files and header files
- illustrating how to use NaCl and Pepper, along with a Makefile to build
- the example using each of the toolchains.
-
-tools
- The SDK includes a number of additional tools that you can use for
- tasks such as validating Native Client modules and running modules
- from the command line.
+The Native Client SDK includes:
+
+- **Support for multiple Pepper versions** to compile for specific minimum
+ versions of Chrome.
+- **Update utility** to download new bundles and updates to existing bundles.
+- **Toolchains** to compile for Portable Native Client (PNaCl), traditional
+ Native Client (NaCl), and for compiling architecture-specific Native Client
+ applications with glibc.
+- **Examples** Including C or C++ source files and header files illustrating
+ how to use NaCl and Pepper, and Makefiles to build the example with each of
+ the toolchains.
+- **Tools** for validating Native Client modules and running modules from the
+ command line.
Follow the steps below to download and install the Native Client SDK.

+
Prerequisites
-------------
-* **Python:** Make sure you have Python 2.6 or 2.7 installed, and that the
- Python executable is in your path.
-
- * On Mac/Linux, Python is likely preinstalled. Run the command ``"python
- -V``" in a terminal window, and make sure that the version of Python you
- have is 2.6.x or 2.7.x (if it's not, upgrade to one of those versions).
- * On Windows, you may need to install Python. Go to
- `http://www.python.org/download/ <http://www.python.org/download/>`_ and
- select the latest 2.x version. In addition, be sure to add the Python
- directory (for example, ``C:\python27``) to the PATH `environment
- variable <http://en.wikipedia.org/wiki/Environment_variable>`_. After
- you've installed Python, run the command ``"python -V``" in a Command
- Prompt window and verify that the version of Python you have is 2.6.x or
- 2.7.x.
- * Note that Python 3.x is not yet supported.
-
-* **Make:** On the Mac, you need to install the ``make`` command on your system
- before you can build and run the examples in the SDK. One easy way to get
- ``make``, along with several other useful tools, is to install
- `Xcode Developer Tools <https://developer.apple.com/technologies/tools/>`_.
- After installing Xcode, go to the Preferences menu, select
- Downloads and Components, and verify that Command Line Tools are installed.
- If you'd rather not install Xcode, you can download and build an
- `open source version
- <http://mac.softpedia.com/dyn-postdownload.php?p=44632&t=4&i=1>`_ of
- ``make``. In order to build the command you may also need to download and
- install a copy of `gcc <https://github.com/kennethreitz/osx-gcc-installer>`_.

-----------------------------
-
-#. Download the SDK update utility: `nacl_sdk.zip
+.. _python26-27:
+
+Python 2.7
+^^^^^^^^^^^^^^^^^
+
+Make sure that the Python executable is in your ``PATH`` variable. Python 3.x is
+not yet supported.
+
+* On Mac and Linux, Python is likely preinstalled. Run the command ``python -V``
+ in a terminal window, and make sure that the version you have is 2.6.x or
+ 2.7.x.
+* On Windows, you may need to install Python. Go to `http://www.python.org/
+ download/ <http://www.python.org/download/>`_ and select the latest 2.x
+ version. In addition, be sure to add the Python directory (for example,
+ ``C:\python27``) to the ``PATH`` `environment variable <http://en.wikipedia.
+ org/wiki/Environment_variable>`_. Run ``python -V`` from a command line to
+ verify that you properly configured the PATH variable.

+Make
+^^^^
+
+* On the Mac, you need to install ``make`` on your system before you can build
+ and run the examples in the SDK. One easy way to get ``make``, along with
+ several other useful tools, is to install `Xcode Developer Tools
+ <https://developer.apple.com/technologies/tools/>`_. After installing Xcode,
+ go to the XCode menu, open the Preferences dialog box then select Downloads
+ and Components. Verify that Command Line Tools are installed. If you'd rather
+ not install Xcode, you can download and build an `open source version
+ <http://mac.softpedia.com/dyn-postdownload.php?p=44632&t=4&i=1>`_ of ``make``.
+ To build the program you may also need to download and install `gcc
+ <https://github.com/kennethreitz/osx-gcc-installer>`_.
+* On Windows, the Native Client SDK includes a copy of GNU Make.
+
+.. _platforms:
+
+Platforms
+---------
+
+Native Client supports several operating systems, including Windows, Linux, OSX,
+and ChromeOS. It supports several architectures including on x86-32, x86-64,
+ARM, and MIPS.
+
+.. _versioning:
+
+Versions
+--------
+
+Chrome is released on a six week cycle, and developer versions of Chrome are
+pushed to the public beta channel three weeks before each release. As with any
+software, each release of Chrome may include changes to Native Client and the
+Pepper interfaces that may require modification to existing applications.
+However, modules compiled for one version of Pepper/Chrome should work with
+subsequent versions of Pepper/Chrome. The SDK includes multiple versions of the
+Pepper APIs to help developers make adjustments to API changes and take
+advantage of new features: `stable </native-client/pepper_stable>`_, `beta
+</native-client/pepper_beta>`_ and `dev </native-client/pepper_dev>`_.

- for download, and that you have already installed the latest revision of the
- ``sdk_tools`` bundle (it was included in the zip file you downloaded).
- Each bundle is labeled post-stable, stable, beta, dev, or canary.

- Chrome users. This is because Native Client is designed to be
- backward-compatible (for example, applications developed with the

- By default, ``naclsdk`` only downloads bundles that are
- recommended---generally those that are "stable." Continuing with the earlier example, the
- "update" command would only download the ``pepper_31``
- bundle, since the bundles ``pepper_32`` and greater are not yet stable.
- If you want the ``pepper_32`` bundle, you must ask for it explicitly::
