mdpack: Markdown Bundler

mdpack is a markdown bundler that enables the composition of markdown and HTML files, treating them similarly to how JavaScript modules are imported. It processes custom `@@import` statements to combine content from various files and can output the bundled result in both markdown and HTML formats. The package, currently at version 0.5.2 (last published in August 2018), provides both a Command Line Interface (CLI) and a Node.js API for programmatic use. Key features include a plugin system, allowing extensions for tasks like HTML minification or adding banners and footers to the bundled output. While the project's README mentions alternatives like `docz` and labels its section on it as "Deprecated" (referring to `docz` or its own aspiration), `mdpack` differentiates itself through its specific custom import syntax and its dual output capabilities for markdown and HTML. Its release cadence is currently inactive, given the last publish date.
