Detailed Description

Implementations of the framework for the SearXNG engines.

- :py:obj:`searx.enginelib.EngineCache`
- :py:obj:`searx.enginelib.Engine`
- :py:obj:`searx.enginelib.traits`

There is a command line for developer purposes and for deeper analysis.  Here is
an example in which the command line is called in the development environment::

  $ ./manage pyenv.cmd bash --norc --noprofile
  (py3) python -m searx.enginelib --help

.. hint::

   The long term goal is to modularize all implementations of the engine
   framework here in this Python package.  ToDo:

   - move implementations of the :ref:`searx.engines loader` to a new module in
     the :py:obj:`searx.enginelib` namespace.
