"""**Chains** are easily reusable components linked together.

Chains encode a sequence of calls to components like models, document retrievers,
other Chains, etc., and provide a simple interface to this sequence.

The Chain interface makes it easy to create apps that are:

    - **Stateful:** add Memory to any Chain to give it state,
    - **Observable:** pass Callbacks to a Chain to execute additional functionality,
      like logging, outside the main sequence of component calls,
    - **Composable:** combine Chains with other components, including other Chains.

**Class hierarchy:**

.. code-block::

    Chain --> <name>Chain  # Examples: LLMChain, MapReduceChain, RouterChain
