+Installation
+------------
+pyOpenSSL uses distutils.  Use setup.py to install it in the usual way:
 
-INSTALLATION INSTRUCTIONS FOR pyOpenSSL
-------------------------------------------------------------------------------
+  $ python setup.py install --user
 
-I have tested this on Debian Linux systems (woody and sid), Solaris 2.6 and
-2.7. Others have successfully compiled it on Windows and NT.
+Or use pip:
 
-
--- Building the Module on a Unix System --
-
-pyOpenSSL uses distutils, so there really shouldn't be any problems. To build
-the library:
-
-  $ python setup.py build
-
-If your OpenSSL header files aren't in /usr/include, you may need to supply
-the -I flag to let the setup script know where to look. The same goes for the
-libraries of course, use the -L flag. Note that build won't accept these
-flags, so you have to run first build_ext and then build! Example:
-
-  $ python setup.py build_ext -I/usr/local/ssl/include -L/usr/local/ssl/lib
-  $ python setup.py build
-
-Now you should have a directory called OpenSSL that contains e.g. SSL.so and
-__init__.py somewhere in the build dicrectory, so just:
-
-  $ python setup.py install
-
-If you, for some arcane reason, don't want the module to appear in the
-site-packages directory, use the --prefix option.
+  $ pip install --user .
 
 You can, of course, do
 
   $ python setup.py --help
 
-to find out more about how to use the script.
-
-
--- Building the Module on a Windows System --
-
-First you should get OpenSSL linked with the same runtime library that Python
-uses.  If you are using Python 2.6 you can use the installer at:
-
-  http://www.slproweb.com/products/Win32OpenSSL.html
-
-The binaries in the installer are built with Visual Studio 2008 at the
-time of this writing, which is the same compiler used for building the
-official Python 2.6 installers.
-
-If you want to build pyOpenSSL for an older Python version, it is preferred
-to build OpenSSL yourself, either with the Visual Studio 2003 compiler or
-with the MinGW compiler.  This way you avoid all potential incompatibilities
-between different versions of runtime library (msvcrt.dll).  To build
-OpenSSL follow the instructions in its source distribution and make sure
-that you build a shared library, not a static one.  pyOpenSSL fails some of
-its tests when linked with the static OpenSSL libraries.  Use the same
-compiler for OpenSSL that you will use for pyOpenSSL later.  Make sure that
-OpenSSL is properly installed before continuing.  To install OpenSSL when
-building with MinGW, use the folowing script:
-
-set OPENSSL_INSTALL_DIR=%1
-mkdir %OPENSSL_INSTALL_DIR%
-mkdir %OPENSSL_INSTALL_DIR%\bin
-mkdir %OPENSSL_INSTALL_DIR%\include
-mkdir %OPENSSL_INSTALL_DIR%\include\openssl
-mkdir %OPENSSL_INSTALL_DIR%\lib
-copy /b .\*.dll            %OPENSSL_INSTALL_DIR%\bin
-copy /b .\out\openssl.exe  %OPENSSL_INSTALL_DIR%\bin
-copy /b .\outinc\openssl\* %OPENSSL_INSTALL_DIR%\include\openssl
-copy /b .\out\*.a          %OPENSSL_INSTALL_DIR%\lib
-
-Ensure that OpenSSL's openssl.exe executable can be found on PATH before
-running pyOpenSSL's setup script.  The setup script finds OpenSSL's include
-dir and lib dir based on the location of openssl.exe, and the test suite
-requires openssl.exe for output comparison.  Alternatively, you can specify
-the --with-openssl option to setup.py's build_ext command with the path to
-the OpenSSL installation dir:
+or
 
-  > python setup.py build_ext --with-openssl=C:\path\to\openssl build
+  $ pip install --help
 
-pyOpenSSL is known to build with mingw32 for Python 2.3 through Python 2.5.
-Before using the mingw32 compiler for Python 2.3, you will have to create
-a Python library that MinGW understands. Find and download the pexports
-program, put it and MinGW's bin directory on path, then run from Python's
-install dir:
+to find out more about how to use these tools.
 
-> pexports python23.dll > libs\python23.def
-> dlltool --dllname python23.dll --def libs\python23.def \
-          --output-lib libs\libpython23.a
+Documentation
+-------------
 
-For Python 2.4 and 2.5, no special preparation is needed, just make sure that
-MinGW's gcc is on PATH.  You can specify that mingw32 be used by passing
-the --compiler argument to build_ext:
-
-  C:\pyOpenSSL-X.Y> setup.py build_ext -c mingw32 bdist_msi
-
-The bdist_msi command will build an MSI installer.  It can be substituted
-with another bdist command if another kind of installer is desired or with
-the install command if you want to install directly.
-
-For Python 2.4 and 2.5 you can use Visual Studio 2003 in addition to MinGW.
-For Python 2.6, the official Windows installer of which is built with
-Microsoft Visual Studio 2008 (version 9.0), Microsoft Visual Studio 2008
-(version 9.0) is required.
-
-To build with MSVC, just omit the compiler specific option:
-
-  C:\pyOpenSSL-X.Y> setup.py bdist_msi
-
-The resulting binary distribution will be placed in the dist directory. To
-install it, depending on what kind of distribution you create, run it,
-unzip it, or copy it to Python installation's site-packages.
-
-And similarily, you can do
-
-    setup.py --help
-
-to get more information.
-
-Big thanks to Itamar Shtull-Trauring, Oleg Orlov, Zooko O'Whielacronx, Chris
-Galvan, Žiga Seilnacht, and #python and #distutils on FreeNode for their
-help with Windows build instructions and to Michael Schneider for providing
-Windows build hosts.

--- Documentation --
-
-The documentation is written in LaTeX, using the standard Python templates,
-and tools to compile it into a number of forms are included.  You need to
-supply things like dvips, latex2html yourself of course!
+The documentation is written in reStructuredText and build using Sphinx.
 
 To build the text, html, postscript or dvi forms of the documentation, this is
 what you do:
@@ -136,11 +31,3 @@ what you do:
     make text
     # To make the dvi form:
     make dvi
-
-It's as simple as that.  Note that since Python's mkhowto script is used, if
-you do first ``make dvi'' and then ``make ps'', the dvi file will disappear.
-I included a special build target ``make all'' that will build all the
-documentation in an order that won't let anything disappear.

-    /*
-     * Sit back and I'll tell you a story of intrigue and corruption, deceit and
-     * murder.
-     *
-     * A Py_buffer is used to hold any kind of byte-like data - a string, a
-     * memoryview, a buffer, etc.  PyArg_ParseTuple takes whatever kind of
-     * object was supplied, notices the "s*" format specifier, and tries to copy
-     * the metadata for that object into the Py_buffer also passed in.
-     *
-     * According to the Python documentation:
-     *
-     *     ... the caller is responsible for calling PyBuffer_Release with the
-     *     structure after it has processed the data.
-     *
-     * Correct use of PyBuffer_Release is necessary due to the fact that
-     * Py_buffer must hold a reference to the original Python object from which
-     * it was initialized.  PyBuffer_Release will decrement the reference count
-     * of that original object, allowing it to eventually be deallocated - but
-     * only after the Py_buffer is no longer in use.
-     *
-     * To support failures partway through parsing a format string,
-     * PyArg_ParseTuple maintains an internal PyListObject of PyCObjects it has
-     * created so far.  This allows it to easily clean up these objects when
-     * parsing fails, before returning an error to the caller (incidentally, it
-     * also makes sure to clean up the Py_buffer it initialized in this case, by
-     * calling PyBuffer_Release - which means the caller *must not* use
-     * PyBuffer_Release when PyArg_ParseTuple fails; not exactly what the
-     * documentation directs).
-     *
-     * The PyCObjects are given destructors which clean up some structure
-     * PyArg_ParseTuple has created (or initialized) - often another PyObject
-     * which needs to be decref'd.
-     *
-     * When parsing completes, the reference count of the PyListObject is merely
-     * decremented.  The normal Python garbage collection logic (the reference
-     * counting logic, in this case) takes over and collects both the list and
-     * all of the objects in it.  When each PyCObject in the list is collected,
-     * it triggers its destructor to clean up the structure it wraps.  This all
-     * happens immediately, before the Py_XDECREF of the PyListObject returns.
-     *
-     * The PyListObject is similarly destroyed in the success case, but not
-     * until each PyCObject it contains has had its destructor set to NULL to
-     * prevent it from cleaning up its contents.
-     *
-     * When PyArg_ParseTuple returns in an error case, therefore,
-     * PyRelease_Buffer has already been used on the Py_buffer passed to
-     * PyArg_ParseTuple.
-     *
-     * This is fortuitous, as the Py_buffer is typically (always?) allocated on
-     * the stack of the caller of PyArg_ParseTuple.  Once that caller returns,
-     * that stack memory is no longer valid, and the Py_buffer may no longer be
-     * used.
-     *
-     * On a Python runtime which does not use reference counting, the
-     * PyListObject may not actually be collected before Py_XDECREF returns.  It
-     * may not even be collected before PyArg_ParseTuple returns.  In fact, in
-     * particularly unfortunate cases, it may even not be collected before the
-     * caller of PyArg_ParseTuple returns.  It may not be called until long,
-     * long after the stack memory the Py_buffer was allocated on has been
-     * re-used for some other function call, after the memory holding a pointer
-     * to the structure that owns the memory the Py_buffer wrapped has been
-     * overwritten.  When PyBuffer_Release is used on the Py_buffer in this
-     * case, it will try to decrement a random integer - probably part of a
-     * local variable on some part of the stack.
-     *
-     * The PyPy runtime does not use reference counting.
-     *
-     * The solution adopted here is to allocate the Py_buffer on the heap,
-     * instead.  As there is no mechanism for learning when the PyCObject used
-     * by PyArg_ParseTuple to do its internal cleanup has had its way with the
-     * Py_buffer, the Py_buffer is leaked in the error case, to ensure it is
-     * still valid whenever PyBuffer_Release is called on it.
-     *
-     * Real programs should rarely, if ever, trigger the error case of
-     * PyArg_ParseTuple, so this is probably okay.  Plus, I'm tired of this
-     * stupid bug. -exarkun

- * CALLBACKS
- *
- * Callbacks work like this: We provide a "global" callback in C which
- * transforms the arguments into a Python argument tuple and calls the
- * corresponding Python callback, and then parsing the return value back into
- * things the C function can return.
- *
- * Three caveats:
- *  + How do we find the Context object where the Python callbacks are stored?
- *  + What about multithreading and execution frames?
- *  + What about Python callbacks that raise exceptions?
- *
- * The solution to the first issue is trivial if the callback provides
- * "userdata" functionality. Since the only callbacks that don't provide
- * userdata do provide a pointer to an SSL structure, we can associate an SSL
- * object and a Connection one-to-one via the SSL_set/get_app_data()
- * functions.
- *
- * The solution to the other issue is to rewrite the Py_BEGIN_ALLOW_THREADS
- * macro allowing it (or rather a new macro) to specify where to save the
- * thread state (in our case, as a member of the Connection/Context object) so
- * we can retrieve it again before calling the Python callback.
