It provides a PDAL extension module to control Python interaction with PDAL.
Additionally, you can use it to fetch `schema`_ and `metadata`_ from PDAL operations.

Build
--------------------------------------------------------------------------------
You can build the extension with cmake in the standard way: create a build directory
at the top level of the source tree, run cmake from that build directory and then
run the build tool. If you're a developer, you can then include the build
directory in your PYTHONPATH and then execute Python programs using PDAL without
installation of the extension. This is an example of commands to be executed from
the directory containing this README file for a linux-like system using the Ninja
build tool:

.. code-block::

mkdir build
cd build
cmake -G Ninja ..
ninja
EXPORT PYTHONPATH=.
