This is a Jupyter notebook based environment for SELinux policy analysis that let’s you mix queries, Python code, and Markdown formatted notes into an executable document.

I really think that this is the most productive environment that I’ve seen for real policy analysis (and I’ve been working on SELinux policy analysis and tools for almost 15 years). The ability to quickly create custom tools to answer hard questions combined inline with well-formatted documentation makes a huge difference. > > > > SPAN has been used so far to analyze 3 large, complex, custom systems with very large policies (hundreds of custom domains).

Jupyter notebooks are an interactive environment that let you write text (in Markdown) and code together. You can get a feel for what's possible in this awesome notebook on Regex Golf from XKCD: http://nbviewer.jupyter.org/url/norvig.com/ipython/xkcd1313.ipynb <http://nbviewer.jupyter.org/url/norvig.com/ipython/xkcd1313.ipynb>.
