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 ('<div>', '<table>' etc.). Note that by default Markdown isn't
interpreted in HTML block-level elements, unless you add a 'markdown=1"'
attribute to the element. See the Text::Markdown manpage for details.
