Novella is a build system for processing files in a temporary directory isolated from the project source code. It is designed for the preprocessing of documentation source code such as Markdown files before they are passed into a static site generator such as Mkdocs or Hugo. Novella was designed as the backbone for Pydoc-Markdown, but can be used independently.
Check out the Novella Documentation for more information.
Note: Novella is currently a work in progress project and is considered unstable.
