Hello, World!
============
Author Name, <author@domain.foo>
you can write text http://example.com[with links], optionally
using an explicit link:http://example.com[link prefix].
* single quotes around a phrase place 'emphasis'
** alternatively, you can put underlines around a phrase to add _emphasis_
* astericks around a phrase make the text *bold*
* pluses around a phrase make it +monospaced+
- escape characters are supported
- you can escape a quote inside emphasized text like 'here\'s johnny!'
