Add Google Analytics Without Plugin to Each theme

[Master Shake]

How can I Add Google Analytics tracking to every wordpress theme without using a plugin? Is there just one file I can modify?

Try this:

file: wp-includes/general-template.php

find:
function wp_footer() {
do_action('wp_footer');


add below:
?>
<!----Google Analytics Code----->
<?

Thanks! That seems to work fine.
