"""This module implements the :origin:`searxng_msg <babel.cfg>` extractor to
extract messages from:

- :origin:`searx/searxng.msg`

The ``searxng.msg`` files are selected by Babel_, see Babel's configuration in

    searxng_msg = searx.babel_extract.extract
    [searxng_msg: **/searxng.msg]

A ``searxng.msg`` file is a python file that is *executed* by the
:py:obj:`extract` function.  Additional ``searxng.msg`` files can be added by:

1. Adding a ``searxng.msg`` file in one of the SearXNG python packages and
2. implement a method in :py:obj:`extract` that yields messages from this file.
