%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) "Retrieval-Augmented Generation for Large Language Models: A
Survey" <doi:10.48550/arXiv.2312.10997>.
