Builds and installs Envoy protocol buffers and the following
dependencies:

* data-plane-api
* googleapis
* protoc-gen-validate
* opencensus-proto


How it works
------------

Clones the Envoy repository and associated dependencies to a temporary
location. Builds the proto files into virtual Python module and installs
the module with pip. The protobuf files are available in ``envoy_proto``.


Installation
------------

.. code::

    pip installl envoy-proto-builder

Usage
-----

Running with no arguments will install the Envoy files from the master branch.

.. code::

    usage: envoy-protobuf-builder [-h] [--version VERSION] [--src-dir SRC_DIR] [--no-clone]

    optional arguments:
      -h, --help         show this help message and exit
      --version VERSION  The Envoy version to build. Defaults to master.
      --src-dir SRC_DIR  The directory to clone the repositories to. If not specified a temporary
                         location is used.
      --no-clone         Build the files with cloning the repositories.
