Smu is capable to parse very large documents.  As long as you avoid an huge
amount of indents it scales just great.

Smu was started as a rewrite of Markdown but became something more
lightweight and consistent.  The biggest difference between Markdown
and smu is that smu doesn't support reference style links.")
