Excerpts, please!

Hey,
Zuari is a hot candidate for my blog. But I have the same problem. I’d like to stick to using excerpts.
“Read more” is not an option unfortunately, as this would mean that I’d have to edit several hundred posts…
I hoped it would be as easy as replacing “the_content” with “the_excerpt” in some files, but it is not.
So it would be great if you could add that option.
Cheers!
M.
