Initial import of p5-Text-Markdown-1.0.3:

Markdown is a text-to-HTML filter; it translates an easy-to-read
/ easy-to-write structured text format into HTML. Markdown's text
format is most similar to that of plain text email, and supports
features such as headers, *emphasis*, code blocks, blockquotes,
and links.

Markdown's syntax is designed not as a generic markup language,
but specifically to serve as a front-end to (X)HTML. You can use
span-level HTML tags anywhere in a Markdown document, and you can
use block level HTML tags (like <div> and <table> as well).
