How to make a separator in my menu, between the links?

basically, i have a menu with the following items: "home", "site map", and "content" , displayed horizontally.

I would like them to appear like this: "home | site map | content"

, with "|" spacers in between... how can i do this?

btw, i also posted this question here: http://drupal.org/node/128618#comment-220369
...i'm new here, and didnt think my post would be recognized there after i had already done it... sorry.

thanks,
