| NL2BR Extension |
| =============== |
| |
| A Python-Markdown extension to treat newlines as hard breaks; like |
| GitHub-flavored Markdown does. |
| |
| Usage: |
| |
| >>> import markdown |
| >>> print markdown.markdown('line 1\\nline 2', extensions=['nl2br']) |
| <p>line 1<br /> |
| line 2</p> |
| |
| Copyright 2011 [Brian Neal](http://deathofagremmie.com/) |
| |
| Dependencies: |
| * [Python 2.4+](http://python.org) |
| * [Markdown 2.1+](http://packages.python.org/Markdown/) |
