struckdown is an experimental markdown/commonmark processing pipeline library inspired by Python's docutils and Sphinx.

Here is what exists today:
struckdown: a Rust library that implements a structured markdown processing library based onpulldown-cmark.struck: an experimental command line executable to play around with the library.
