List_cats

I have searched the Codex and Support forums and WWW, and can’t find this info. This is the category tag in my theme:

<?php list_cats(0, ”, ‘name’, ‘asc’, ”, 1, 0, 1, 1, 1, 1, 0,”,”,”,”,”) ?>

I think I understand what everything outside the parentheses means. And I understand that the info inside the parentheses defines the parameters that govern how the categories are presented. But what, EXACTLY, do each one of those parameter codes mean? How can I modify the category parameters, if I don’t understand the current values?

Specifically, I want to make all categories display on the list, including categories that have no posts. But more generally, how can I know what all of these parameters mean?
