Requires GitPython.

Grabs the most recent commits to a Git repository, as defined in settings.py. Inspired by Simon Willison's about page.

Example:

{% get_recent_commits 10 as commits %}
<ul>
{% for commit in commits reversed %}
    <li>{{ commit.commited_date }} - {{ commit.message }}</li>
{% endfor %}
</ul>
