hook_form_alter - in module or in template.php

Question

I wanted to perform a quick alteration of ubercart form data (I want to remove links to product nodes in the shopping-cart). I found a solution that involves implementing hook_form_alter() by creating a new module (link and code below).

My question is, do I have to make a new module or can I just add this function into my theme's template.php file? I tried the later but I couldnt get it to work (I renamed the function to theNameOfMyTheme_form_alter).

(The bigger issue here is me trying to get my head round all this drupal 6 override stuff. Eg if I come across some code that I want to alter, how can you tell if you are supposed to create a module or change your theme?).

http://www.ubercart.org/forum/support/2298/remove_product_links_shopping_cart

function your_module_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'uc_cart_view_form') {
    foreach($form['items'] as $key => $item) {
      if(!empty($item['desc']['#value'])) {
        $form['items'][$key]['desc']['#value'] = strip_tags($item['desc']['#value']);
      }
    }
  }
}

Adding to Clive's solution, just to confirm for anyone else looking for this: hook_form_alter isn't called for themes in Drupal 6.
