-# How to become a contributor and submit your own code
-
-## Contributor License Agreements
-
-We'd love to accept your patches! Before we can take them, we
-have to jump a couple of legal hurdles.
-
-Please fill out either the individual or corporate Contributor License Agreement
-(CLA).
-
-  * If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an
-    [individual CLA](https://developers.google.com/open-source/cla/individual).
-  * If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a
-    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it. Once we receive it, we'll be able to
-accept your pull requests.
-
-## Contributing A Patch
-
-1. Submit an issue describing your proposed change to the repo in question.
-1. The repo owner will respond to your issue promptly.
-1. If your proposed change is accepted, and you haven't already done so, sign a
-   Contributor License Agreement (see details above).
-1. Fork the desired repo, develop and test your code changes.
-1. Ensure that your code adheres to the existing style in the sample to which
-   you are contributing.
-1. Ensure that your code has an appropriate set of unit tests which all pass.
-1. Submit a pull request.
-
-## Style
-
-This repository follow the [Google C++ Style Guide](
-https://google.github.io/styleguide/cppguide.html).
-Please make sure your contributions adhere to the style guide.
-
-### Formatting
-
-The code in this project is formatted with `clang-format(1)`, and our CI builds
-will check that the code matches the format generated by this tool before
-accepting a pull request. Please configure your editor or IDE to use the Google
-style for indentation and other whitespace. If you need to reformat one or more
-files, you can simply run `clang-format` manually:
-
-```console
-$ clang-format -i <file>....
-```
-
-If you need to reformat one of the files to match the Google style.  Please be
-advised that `clang-format` has been known to generate slightly different
-formatting in different versions. We use version 7; use the same version if you
-run into problems.

-
-      You may add Your own copyright statement to Your modifications and

-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify

-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# Google Cloud Platform C++ Proto Libraries
-
-Compile the protocol buffer definitions into C++ libraries.
-
-## Requirements
-
-#### Compiler
-
-The Google Cloud C++ libraries are tested with the following compilers:
-
-| Compiler    | Minimum Version |
-| ----------- | --------------- |
-| GCC         | 4.8 |
-| Clang       | 3.8 |
-| MSVC++      | 14.1 |
-| Apple Clang | 8.1 |
-
-#### Build Tools
-
-The Google Cloud C++ Client Libraries can be built with
-[CMake](https://cmake.org) or [Bazel](https://bazel.io).  The minimal versions
-of these tools we test with are:
-
-| Tool       | Minimum Version |
-| ---------- | --------------- |
-| CMake      | 3.5 |
-| Bazel      | 0.24.0 |
-
-#### Libraries
-
-The libraries also depend on gRPC, libcurl, and the dependencies of those
-libraries. The Google Cloud C++ Client libraries are tested with the following
-versions of these dependencies:
-
-| Library | Minimum version |
-| ------- | --------------- |
-| gRPC    | v1.16.x |
-| libcurl | 7.47.0  |
-
-
-## Versioning
-
-Please note that the Google Cloud C++ client libraries do **not** follow
-[Semantic Versioning](http://semver.org/).
-
-**GA**: Libraries defined at a GA quality level are expected to be stable and
-any backwards-incompatible changes will be noted in the documentation. Major
-changes to the API will signaled by changing major version number
-(e.g. 1.x.y -> 2.0.0).
-
-**Beta**: Libraries defined at a Beta quality level are expected to be mostly
-stable and we're working towards their release candidate. We will address issues
-and requests with a higher priority.
-
-**Alpha**: Libraries defined at an Alpha quality level are still a
-work-in-progress and are more likely to get backwards-incompatible updates.
-Additionally, it's possible for Alpha libraries to get deprecated and deleted
-before ever being promoted to Beta or GA.
-

-
-# First install the development tools and OpenSSL. The development tools
-# distributed with CentOS (notably CMake) are too old to build
-# `cpp-cmakefiles`. In these instructions, we use `cmake3` obtained from
-# [Software Collections](https://www.softwarecollections.org/).
-

-RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
-RUN yum install -y centos-release-scl

-

-
-# ```bash

-

-FindProtobufTargets
--------------------
-
-A module to use `Protobuf` with less complications.
-
-Using ``find_package(Protobuf)`` should be simple, but it is not.
-
-CMake provides a ``FindProtobuf`` module. Unfortunately it does not generate
-`protobuf::*` targets until CMake-3.9, and `protobuf::protoc` does not
-appear until CMake-3.10.
-
-The CMake-config files generated by `protobuf` always create these targets,
-but on some Linux distributions (e.g. Fedora>=29, and openSUSE-Tumbleweed) there
-are system packages for protobuf, but these packages are installed without the
-CMake-config files. One must either use the ``FindProtobuf`` module, find the
-libraries via `pkg-config`, or find the libraries manually.
-
-When the CMake-config files are installed they produce the same targets as
-recent versions of ``FindProtobuf``. However, they do not produce the
-`Protobuf_LIBRARY`, `Protobuf_INCLUDE_DIR`, etc. that are generated by the
-module. Furthermore, the `protobuf::protoc` library is not usable when loaded
-from the CMake-config files: its ``IMPORTED_LOCATION`` variable is not defined.
-
-This module is designed to provide a single, uniform, ``find_package()``
-module that always produces the same outputs:
-
-- It always generates the ``protobuf::*`` targets.
-- It always defines ``ProtobufTargets_FOUND`` and ``ProtobufTargets_VERSION``.
-- It *prefers* using the CMake config files if they are available.
-- It fallsback on the ``FindProtobuf`` module if the config files are not found.
-- It populates any missing targets and their properties.
-
-The following :prop_tgt:`IMPORTED` targets are defined:
-
-``protobuf::libprotobuf``
-  The protobuf library.
-``protobuf::libprotobuf-lite``
-  The protobuf lite library.
-``protobuf::libprotoc``
-  The protoc library.
-``protobuf::protoc``
-  The protoc compiler.
-
-Example:
-
-.. code-block:: cmake
-
-  find_package(ProtobufTargets REQUIRED)
-  add_executable(bar bar.cc)
-  target_link_libraries(bar PRIVATE protobuf::libprotobuf)
