Log message:
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.

This module implements the MultiMarkdown markdown syntax
extensions from <http://fletcherpenney.net/multimarkdown/>.
