-Protocol Buffers - Google's data interchange format
-===================================================
-
-[![Build Status](https://travis-ci.org/google/protobuf.svg?branch=master)](https://travis-ci.org/google/protobuf)
-
-Copyright 2008 Google Inc.
-
-This directory contains the Python Protocol Buffers runtime library.
-
-Normally, this directory comes as part of the protobuf package, available
-from:
-
-  https://developers.google.com/protocol-buffers/
-
-The complete package includes the C++ source code, which includes the
-Protocol Compiler (protoc).  If you downloaded this package from PyPI
-or some other Python-specific source, you may have received only the
-Python part of the code.  In this case, you will need to obtain the
-Protocol Compiler from some other source before you can use this
-package.
-
-Development Warning
-===================
-
-The Python implementation of Protocol Buffers is not as mature as the C++
-and Java implementations.  It may be more buggy, and it is known to be
-pretty slow at this time.  If you would like to help fix these issues,
-join the Protocol Buffers discussion list and let us know!
-
-Installation
-============
-
-1) Make sure you have Python 2.6 or newer.  If in doubt, run:
-
-     $ python -V
-
-2) If you do not have setuptools installed, note that it will be
-   downloaded and installed automatically as soon as you run setup.py.
-   If you would rather install it manually, you may do so by following
-   the instructions on this page:
-
-     https://packaging.python.org/en/latest/installing.html#setup-for-installing-packages
-
-3) Build the C++ code, or install a binary distribution of protoc.  If
-   you install a binary distribution, make sure that it is the same
-   version as this package.  If in doubt, run:
-
-     $ protoc --version
-
-4) Build and run the tests:
-
-     $ python setup.py build
-     $ python setup.py test
-
-     To build, test, and use the C++ implementation, you must first compile
-     libprotobuf.so:
-
-     $ (cd .. && make)
-
-     On OS X:
-
-      If you are running a homebrew-provided python, you must make sure another
-      version of protobuf is not already installed, as homebrew's python will
-      search /usr/local/lib for libprotobuf.so before it searches ../src/.libs
-      You can either unlink homebrew's protobuf or install the libprotobuf you
-      built earlier:
-
-      $ brew unlink protobuf
-      or
-      $ (cd .. && make install)
-
-     On other *nix:
-
-      You must make libprotobuf.so dynamically available. You can either
-      install libprotobuf you built earlier, or set LD_LIBRARY_PATH:
-
-      $ export LD_LIBRARY_PATH=../src/.libs
-      or
-      $ (cd .. && make install)
-
-     To build the C++ implementation run:
-     $ python setup.py build --cpp_implementation
-
-     Then run the tests like so:
-     $ python setup.py test --cpp_implementation
-
-   If some tests fail, this library may not work correctly on your
-   system.  Continue at your own risk.
-
-   Please note that there is a known problem with some versions of
-   Python on Cygwin which causes the tests to fail after printing the
-   error:  "sem_init: Resource temporarily unavailable".  This appears
-   to be a bug either in Cygwin or in Python:
-     http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html
-   We do not know if or when it might me fixed.  We also do not know
-   how likely it is that this bug will affect users in practice.
-
-5) Install:
-
-    $ python setup.py install
-
-  or:
-
-    $ (cd .. && make install)
-    $ python setup.py install --cpp_implementation
-
-   This step may require superuser privileges.
-   NOTE: To use C++ implementation, you need to export an environment
-   variable before running your program.  See the "C++ Implementation"
-   section below for more details.
-
-Usage
-=====
-
-The complete documentation for Protocol Buffers is available via the
-web at:
-
-  https://developers.google.com/protocol-buffers/
-
-C++ Implementation
-==================
-
-The C++ implementation for Python messages is built as a Python extension to
-improve the overall protobuf Python performance.
-
-To use the C++ implementation, you need to:
-1) Install the C++ protobuf runtime library, please see instructions in the
-   parent directory.
-2) Export an environment variable:
-
-    $ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp
-
-You must set this variable at runtime, before running your program, otherwise
-the pure-Python implementation will be used. In a future release, we will
-change the default so that C++ implementation is used whenever it is available.
