-Quick Start Guide
------------------
-
-1.  Install Microsoft Visual Studio 2015, any edition.
-2.  Install Subversion, and make sure 'svn.exe' is on your PATH.
-3.  Run "build.bat -e" to build Python in 32-bit Release configuration.
-4.  (Optional, but recommended) Run the test suite with "rt.bat -q".
-
-
-Building Python using Microsoft Visual C++
-------------------------------------------
-
-This directory is used to build CPython for Microsoft Windows NT version
-6.0 or higher (Windows Vista, Windows Server 2008, or later) on 32 and 64
-bit platforms.  Using this directory requires an installation of
-Microsoft Visual C++ 2015 (MSVC 14.0) of any edition.  The specific
-requirements are as follows:
-
-Visual Studio Express 2015 for Desktop
-Visual Studio Professional 2015
-    Either edition is sufficient for building all configurations except
-    for Profile Guided Optimization.
-    The Python build solution pcbuild.sln makes use of Solution Folders,
-    which this edition does not support.  Any time pcbuild.sln is opened
-    or reloaded by Visual Studio, a warning about Solution Folders will
-    be displayed, which can be safely dismissed with no impact on your
-    ability to build Python.
-    Required for building 64-bit Debug and Release configuration builds
-Visual Studio Premium 2015
-    Required for building Release configuration builds that make use of
-    Profile Guided Optimization (PGO), on either platform.
-
-All you need to do to build is open the solution "pcbuild.sln" in Visual
-Studio, select the desired combination of configuration and platform,
-then build with "Build Solution".  You can also build from the command
-line using the "build.bat" script in this directory; see below for
-details.  The solution is configured to build the projects in the correct
-order.
-
-The solution currently supports two platforms.  The Win32 platform is
-used to build standard x86-compatible 32-bit binaries, output into the
-win32 sub-directory.  The x64 platform is used for building 64-bit AMD64
-(aka x86_64 or EM64T) binaries, output into the amd64 sub-directory.
-The Itanium (IA-64) platform is no longer supported.  See the "Building
-for AMD64" section below for more information about 64-bit builds.
-
-Four configuration options are supported by the solution:
-Debug
-    Used to build Python with extra debugging capabilities, equivalent
-    to using ./configure --with-pydebug on UNIX.  All binaries built
-    using this configuration have "_d" added to their name:
-    python35_d.dll, python_d.exe, parser_d.pyd, and so on.  Both the
-    build and rt (run test) batch files in this directory accept a -d
-    option for debug builds.  If you are building Python to help with
-    development of CPython, you will most likely use this configuration.
-PGInstrument, PGUpdate
-    Used to build Python in Release configuration using PGO, which
-    requires Premium Edition of Visual Studio.  See the "Profile
-    Guided Optimization" section below for more information.  Build
-    output from each of these configurations lands in its own
-    sub-directory of this directory.  The official Python releases may
-    be built using these configurations.
-Release
-    Used to build Python as it is meant to be used in production
-    settings, though without PGO.
-
-
-Building Python using the build.bat script
-----------------------------------------------
-
-In this directory you can find build.bat, a script designed to make
-building Python on Windows simpler.  This script will use the env.bat
-script to detect one of Visual Studio 2015, 2013, 2012, or 2010, any of
-which may be used to build Python, though only Visual Studio 2015 is
-officially supported.
-
-By default, build.bat will build Python in Release configuration for
-the 32-bit Win32 platform.  It accepts several arguments to change
-this behavior:
-
-   -c <configuration>  Set the configuration (see above)
-   -d                  Shortcut for "-c Debug"
-   -p <platform>       Set the platform to build for ("Win32" or "x64")
-   -r                  Rebuild instead of just building
-   -t <target>         Set the target (Build, Rebuild, Clean or CleanAll)
-   -e                  Use get_externals.bat to fetch external sources
-   -M                  Don't build in parallel
-   -v                  Increased output messages
-
-Up to 9 MSBuild switches can also be passed, though they must be passed
-after specifying any of the above switches.  For example, use:
-
-   build.bat -e -d /fl
-
-to do a debug build with externals fetched as needed and write detailed
-build logs to a file.  If the MSBuild switch requires an equal sign
-("="), the entire switch must be quoted:
-
-   build.bat -e -d "/p:ExternalsDir=P:\cpython-externals"
-
-There may also be other situations where quotes are necessary.
-
-
-C Runtime
----------
-
-Visual Studio 2015 uses version 14 of the C runtime (MSVCRT14).  The
-executables no longer use the "Side by Side" assemblies used in previous
-versions of the compiler.  This simplifies distribution of applications.
-
-The run time libraries are available under the VC/Redist folder of your
-Visual Studio distribution. For more info, see the Readme in the
-VC/Redist folder.
-
-
-Sub-Projects
-------------
-
-The CPython project is split up into several smaller sub-projects which
-are managed by the pcbuild.sln solution file.  Each sub-project is
-represented by a .vcxproj and a .vcxproj.filters file starting with the
-name of the sub-project.  These sub-projects fall into a few general
-categories:
-
-The following sub-projects represent the bare minimum required to build
-a functioning CPython interpreter.  If nothing else builds but these,
-you'll have a very limited but usable python.exe:
-pythoncore
-    .dll and .lib
-python
-    .exe
-make_buildinfo, make_versioninfo
-    helpers to provide necessary information to the build process
-
-These sub-projects provide extra executables that are useful for running
-CPython in different ways:
-pythonw
-    pythonw.exe, a variant of python.exe that doesn't open a Command
-    Prompt window
-pylauncher
-    py.exe, the Python Launcher for Windows, see
-        http://docs.python.org/3/using/windows.html#launcher
-pywlauncher
-    pyw.exe, a variant of py.exe that doesn't open a Command Prompt
-    window
-_testembed
-    _testembed.exe, a small program that embeds Python for testing
-    purposes, used by test_capi.py
-
-These are miscellaneous sub-projects that don't really fit the other
-categories:
-_freeze_importlib
-    _freeze_importlib.exe, used to regenerate Python\importlib.h after
-    changes have been made to Lib\importlib\_bootstrap.py
-bdist_wininst
-    ..\Lib\distutils\command\wininst-14.0[-amd64].exe, the base
-    executable used by the distutils bdist_wininst command
-python3dll
-    python3.dll, the PEP 384 Stable ABI dll
-xxlimited
-    builds an example module that makes use of the PEP 384 Stable ABI,
-    see Modules\xxlimited.c
-
-The following sub-projects are for individual modules of the standard
-library which are implemented in C; each one builds a DLL (renamed to
-.pyd) of the same name as the project:
-_ctypes
-_ctypes_test
-_decimal
-_elementtree
-_hashlib
-_msi
-_multiprocessing
-_overlapped
-_socket
-_testcapi
-_testbuffer
-_testimportmultiple
-pyexpat
-select
-unicodedata
-winsound
-
-The following Python-controlled sub-projects wrap external projects.
-Note that these external libraries are not necessary for a working
-interpreter, but they do implement several major features.  See the
-"Getting External Sources" section below for additional information
-about getting the source for building these libraries.  The sub-projects
-are:
-_bz2
-    Python wrapper for version 1.0.6 of the libbzip2 compression library
-    Homepage:
-        http://www.bzip.org/
-_lzma
-    Python wrapper for the liblzma compression library, using pre-built
-    binaries of XZ Utils version 5.0.5
-    Homepage:
-        http://tukaani.org/xz/
-_ssl
-    Python wrapper for version 1.0.1j of the OpenSSL secure sockets
-    library, which is built by ssl.vcxproj
-    Homepage:
-        http://www.openssl.org/
-
-    Building OpenSSL requires nasm.exe (the Netwide Assembler), version
-    2.10 or newer from
-        http://www.nasm.us/
-    to be somewhere on your PATH.  More recent versions of OpenSSL may
-    need a later version of NASM. If OpenSSL's self tests don't pass,
-    you should first try to update NASM and do a full rebuild of
-    OpenSSL.  get_externals.py also downloads a snapshot of NASM, and the
-    libeay and ssleay sub-projects use that version of nasm.exe.
-
-    The libeay/ssleay sub-projects expect your OpenSSL sources to have
-    already been configured and be ready to build.  If you get your sources
-    from svn.python.org as suggested in the "Getting External Sources"
-    section below, the OpenSSL source will already be ready to go.  If
-    you want to build a different version, you will need to run
-
-       PCbuild\prepare_ssl.py path\to\openssl-source-dir
-
-    That script will prepare your OpenSSL sources in the same way that
-    those available on svn.python.org have been prepared.  Note that
-    Perl must be installed and available on your PATH to configure
-    OpenSSL.  ActivePerl is recommended and is available from
-        http://www.activestate.com/activeperl/
-
-    The libeay and ssleay sub-projects will build the modules of OpenSSL
-    required by _ssl and _hashlib and may need to be manually updated when
-    upgrading to a newer version of OpenSSL or when adding new
-    functionality to _ssl or _hashlib. They will not clean up their output
-    with the normal Clean target; CleanAll should be used instead.
-_sqlite3
-    Wraps SQLite 3.8.3.1, which is itself built by sqlite3.vcxproj
-    Homepage:
-        http://www.sqlite.org/
-_tkinter
-    Wraps version 8.6.1 of the Tk windowing system.
-    Homepage:
-        http://www.tcl.tk/
-
-    Tkinter's dependencies are built by the tcl.vcxproj and tk.vcxproj
-    projects.  The tix.vcxproj project also builds the Tix extended
-    widget set for use with Tkinter.
-
-    Those three projects install their respective components in a
-    directory alongside the source directories called "tcltk" on
-    Win32 and "tcltk64" on x64.  They also copy the Tcl and Tk DLLs
-    into the current output directory, which should ensure that Tkinter
-    is able to load Tcl/Tk without having to change your PATH.
-
-    The tcl, tk, and tix sub-projects do not clean their builds with
-    the normal Clean target; if you need to rebuild, you should use the
-    CleanAll target or manually delete their builds.
-
-
-Getting External Sources
-------------------------
-
-The last category of sub-projects listed above wrap external projects
-Python doesn't control, and as such a little more work is required in
-order to download the relevant source files for each project before they
-can be built.  However, a simple script is provided to make this as
-painless as possible, called "get_externals.bat" and located in this
-directory.  This script extracts all the external sub-projects from
-    http://svn.python.org/projects/external
-via Subversion (so you'll need svn.exe on your PATH) and places them
-in ..\externals (relative to this directory).
-
-It is also possible to download sources from each project's homepage,
-though you may have to change folder names or pass the names to MSBuild
-as the values of certain properties in order for the build solution to
-find them.  This is an advanced topic and not necessarily fully
-supported.
-
-
-Building for AMD64
-------------------
-
-The build process for AMD64 / x64 is very similar to standard builds,
-you just have to set x64 as platform. In addition, the HOST_PYTHON
-environment variable must point to a Python interpreter (at least 2.4),
-to support cross-compilation from Win32.
-
-
-Profile Guided Optimization
----------------------------
-
-The solution has two configurations for PGO. The PGInstrument
-configuration must be built first. The PGInstrument binaries are linked
-against a profiling library and contain extra debug information. The
-PGUpdate configuration takes the profiling data and generates optimized
-binaries.
-
-The build_pgo.bat script automates the creation of optimized binaries.
-It creates the PGI files, runs the unit test suite or PyBench with the
-PGI python, and finally creates the optimized files.
-
-See
-    http://msdn.microsoft.com/en-us/library/e7k32f4k(VS.100).aspx
-for more on this topic.
-
-
-Static library
---------------
-
-The solution has no configuration for static libraries. However it is
-easy to build a static library instead of a DLL. You simply have to set
-the "Configuration Type" to "Static Library (.lib)" and alter the
-preprocessor macro "Py_ENABLE_SHARED" to "Py_NO_ENABLE_SHARED". You may
-also have to change the "Runtime Library" from "Multi-threaded DLL
-(/MD)" to "Multi-threaded (/MT)".
-
-
-Visual Studio properties
-------------------------
-
-The PCbuild solution makes use of Visual Studio property files (*.props)
-to simplify each project. The properties can be viewed in the Property
-Manager (View -> Other Windows -> Property Manager) but should be
-carefully modified by hand.
-
-The property files used are:
- * python (versions, directories and build names)
- * pyproject (base settings for all projects)
- * openssl (used by libeay and ssleay projects)
- * tcltk (used by _tkinter, tcl, tk and tix projects)
-
-The pyproject property file defines all of the build settings for each
-project, with some projects overriding certain specific values. The GUI
-doesn't always reflect the correct settings and may confuse the user
-with false information, especially for settings that automatically adapt
-for diffirent configurations.
-
-
-Your Own Extension DLLs
------------------------
-
-If you want to create your own extension module DLL (.pyd), there's an
-example with easy-to-follow instructions in ..\PC\example\; read the
-file readme.txt there first.

+    required by _ssl and _hashlib and may need to be manually updated when
+    upgrading to a newer version of OpenSSL or when adding new
+    functionality to _ssl or _hashlib. They will not clean up their output
+    with the normal Clean target; CleanAll should be used instead.
+_sqlite3
+    Wraps SQLite 3.8.3.1, which is itself built by sqlite3.vcxproj
+    Homepage:
+        http://www.sqlite.org/
+_tkinter
+    Wraps version 8.6.1 of the Tk windowing system.
+    Homepage:
+        http://www.tcl.tk/
+
+    Tkinter's dependencies are built by the tcl.vcxproj and tk.vcxproj
+    projects.  The tix.vcxproj project also builds the Tix extended
+    widget set for use with Tkinter.
+
+    Those three projects install their respective components in a
+    directory alongside the source directories called "tcltk" on
+    Win32 and "tcltk64" on x64.  They also copy the Tcl and Tk DLLs
+    into the current output directory, which should ensure that Tkinter
+    is able to load Tcl/Tk without having to change your PATH.
+
+    The tcl, tk, and tix sub-projects do not clean their builds with
+    the normal Clean target; if you need to rebuild, you should use the
+    CleanAll target or manually delete their builds.
+
+
+Getting External Sources
+------------------------
+
+The last category of sub-projects listed above wrap external projects
+Python doesn't control, and as such a little more work is required in
+order to download the relevant source files for each project before they
+can be built.  However, a simple script is provided to make this as
+painless as possible, called "get_externals.bat" and located in this
+directory.  This script extracts all the external sub-projects from
+    http://svn.python.org/projects/external
+via Subversion (so you'll need svn.exe on your PATH) and places them
+in ..\externals (relative to this directory).
+
+It is also possible to download sources from each project's homepage,
+though you may have to change folder names or pass the names to MSBuild
+as the values of certain properties in order for the build solution to
+find them.  This is an advanced topic and not necessarily fully
+supported.
+
+
+Building for AMD64
+------------------
+
+The build process for AMD64 / x64 is very similar to standard builds,
+you just have to set x64 as platform. In addition, the HOST_PYTHON
+environment variable must point to a Python interpreter (at least 2.4),
+to support cross-compilation from Win32.
+
+
+Profile Guided Optimization
+---------------------------
+
+The solution has two configurations for PGO. The PGInstrument
+configuration must be built first. The PGInstrument binaries are linked
+against a profiling library and contain extra debug information. The
+PGUpdate configuration takes the profiling data and generates optimized
+binaries.
+
+The build_pgo.bat script automates the creation of optimized binaries.
+It creates the PGI files, runs the unit test suite or PyBench with the
+PGI python, and finally creates the optimized files.
+
+See
+    http://msdn.microsoft.com/en-us/library/e7k32f4k(VS.100).aspx
+for more on this topic.
+
+
+Static library
+--------------
+
+The solution has no configuration for static libraries. However it is
+easy to build a static library instead of a DLL. You simply have to set
+the "Configuration Type" to "Static Library (.lib)" and alter the
+preprocessor macro "Py_ENABLE_SHARED" to "Py_NO_ENABLE_SHARED". You may
+also have to change the "Runtime Library" from "Multi-threaded DLL
+(/MD)" to "Multi-threaded (/MT)".
+
+
+Visual Studio properties
+------------------------
+
+The PCbuild solution makes use of Visual Studio property files (*.props)
+to simplify each project. The properties can be viewed in the Property
+Manager (View -> Other Windows -> Property Manager) but should be
+carefully modified by hand.
+
+The property files used are:
+ * python (versions, directories and build names)
+ * pyproject (base settings for all projects)
+ * openssl (used by libeay and ssleay projects)
+ * tcltk (used by _tkinter, tcl, tk and tix projects)
+
+The pyproject property file defines all of the build settings for each
+project, with some projects overriding certain specific values. The GUI
+doesn't always reflect the correct settings and may confuse the user
+with false information, especially for settings that automatically adapt
+for diffirent configurations.
+
+
+Your Own Extension DLLs
+-----------------------
+
+If you want to create your own extension module DLL (.pyd), there's an
+example with easy-to-follow instructions in ..\PC\example\; read the
+file readme.txt there first.
