[themes] Determine Home Page

[Tom Holmes Jr.]

I'm a newbie to Drupal Theme development, and I'm starting with 
BlueMarine because we want a table based theme.
We're porting a static HTML web-site to Drupal, and it's all table-based.  
I'm gonna have to use that Import-HTML module to get the main content 
into Drupal.

So this static web-site has it's own primary links in the header, and 
it's not consistent.
One one home-page I have 6 items, on most of the other pages it is 3 
items, and a few have 4 items.
So, I am just wondering how I can determine which page is the home page ...
then I can do some PHP to determine how to output that header menu.

BTW, I did order the Drupal 5 Themes book, I own the Packt Drupal book, 
and the Pro Drupal Development book.
I am also on the Drupal site and looking at the documentation of how to 
create a theme.
So, I am doing as much research as possible.  

Thanks!
