Description: Provides tools for implementing Retrieval-Augmented
        Generation (RAG) workflows with Large Language Models (LLM).
        Includes functions for document processing, text chunking,
        embedding generation, storage management, and content
        retrieval. Supports various document types and embedding
        providers ('Ollama', 'OpenAI'), with 'DuckDB' as the default
        storage backend. Integrates with the 'ellmer' package to equip
        chat objects with retrieval capabilities. Designed to offer
        both sensible defaults and customization options with
        transparent access to intermediate outputs.  For a review of
        retrieval-augmented generation methods, see Gao et al. (2023)

        Survey" <doi:10.48550/arXiv.2312.10997>.
