This directory contains the code to extract specific sections of user-specific
configuration files for different parts of Pigweed.

There are two different supported structures for extracting sections:

.. code-block:: yaml

   section_title:
     foo: bar

.. code-block:: yaml

   config_title: section_title
   foo: bar

In addition, section titles can be nested:

.. code-block:: yaml

   section_title:
     subtitle:
       subsubtitle:
         foo: bar

.. code-block:: yaml

   config_title: section_title.subtitle.subsubtitle
   foo: bar

Similar data structures are also supported in JSON and TOML.
