nbsphinx is a Sphinx extension that provides a source parser for
*.ipynb files. Custom Sphinx directives are used to show Jupyter
Notebook code cells (and of course their results) in both HTML and
LaTeX output. Un-evaluated notebooks -- i.e. notebooks without
stored output cells -- will be automatically executed during the
Sphinx build process.
