The document discusses the creation of a web-based dashboard for maintainers of CRAN packages, highlighting the need for improved tools to manage package maintainability and address issues caused by dependency changes. It details the architecture of the maintainer tool, its required libraries, and installation procedures, along with links to its GitHub repository and a demo video. Future work includes enhancements for a command line interface and overall performance optimization.
