How to truncate content on One Page template

Permalink Browser Info Environment
On my primary blog page I've set the Blog List template to One Page, and it's showing the post contents instead of descriptions, as it should. The only thing I can't figure out is how to truncate the content and have a "read more" link that would go to the entry's page. Is there a way to do this? Some posts are just too long, would prefer they be kept to the first paragraph in the Blog List.

This is a great package, makes setting up a simple blog very easy. Thanks!
