This makes it super easy to write something cool on Reddit or whatever, then just paste the markdown into an index.smd file in a new directory (named meaningfully) and poof it's in a webpage.

The core of all of it is a /var/www/cgi-bin/markdown-to-html program centered on:

    python3 -m markdown -x codehilite -x fenced_code -x toc

  # This works, with setup in /etc/apache2/conf-enabled/mod-ext_filter-adds.conf
  AddType text/markdown .md
  AddType text/markdown .smd 
  AddOutputFilter markdown-to-html            md
  AddOutputFilter markdown-to-shtml;INCLUDES smd

Separately, be cautious of people putting illegal content on your platform.

Also, nice project - I like the thinking here.

First thing that came to my mind: how do I "curl" a md to it?

But then, I don't know how you intend to manage spam/abuse
