[themes] Autogenerated Lists

[Peter Anderson]

Hi Miles,

The theme() function outputs code in a way that allows users to override 
it if necessary. To see how any theme() function works, look it up on 
http://api.drupal.org (making the first parameter part of the function 
name).
For example: theme('links', ...) would become theme_links(): 
http://api.drupal.org/api/function/theme_links/6
And theme('image', ...) would become theme_image(): 
http://api.drupal.org/api/function/theme_image/6

The primary and secondary links are output via a theme function as 
they're placed into an unordered list (see the code at the above URL). 
This makes it easy to output the primary or secondary links anywhere in 
your page template without having to re-write the unordered list each 
time; but you can always override the theme function in your 
template.php file if you want to change the unordered list to something 
else.

Variables such as $page_title aren't output via a theme function as 
they're just that; variables. They don't have any formatting associated 
with them, so you have to format them yourself in page.tpl.php, like 
putting them in H1 tags or whatever.
Hope that helps explain it a bit.
