Zinnia entry summary

I'm currently building a blogging site with Django / Zinnia (latest version), and am having some trouble with controlling the entries summary.

Two questions:

• How can I display an entry summary? (in a sidebar) I cannot find template tags or parameters that control that specific point.
• How can I control the length of the summary? (e.g. max 130 characters)

Zinnia's Entry model has an excerpt attribute, if thats what you mean my summary.

You'll need to override entry-detail template if you want to add the summary to sidebar for a blog entry.

And to limit characters for excerpt you can extend the entry model
