   8   * ABOUT THE TEMPLATE.PHP FILE
   9   *
  10   *   The template.php file is one of the most useful files when creating or
  11   *   modifying Drupal themes. You can add new regions for block content, modify
  12   *   or override Drupal's theme functions, intercept or make additional
  13   *   variables available to your theme, and create custom PHP logic. For more
  14   *   information, please visit the Theme Developer's Guide on Drupal.org:
  15   *   http://drupal.org/theme-guide
  16   *
  17   * OVERRIDING THEME FUNCTIONS
  18   *
  19   *   The Drupal theme system uses special theme functions to generate HTML
  20   *   output automatically. Often we wish to customize this HTML output. To do
  21   *   this, we have to override the theme function. You have to first find the
  22   *   theme function that generates the output, and then "catch" it and modify it
  23   *   here. The easiest way to do it is to copy the original function in its
  24   *   entirety and paste it here, changing the prefix from theme_ to STARTERKIT_.
  25   *   For example:
  26   *
  27   *     original: theme_breadcrumb()
  28   *     theme override: STARTERKIT_breadcrumb()
  29   *
  30   *   where STARTERKIT is the name of your sub-theme. For example, the
  31   *   zen_classic theme would define a zen_classic_breadcrumb() function.
  32   *
  33   *   If you would like to override any of the theme functions used in Zen core,
  34   *   you should first look at how Zen core implements those functions:
  35   *     theme_breadcrumbs()      in zen/template.php
  36   *     theme_menu_item_link()   in zen/template.php
  37   *     theme_menu_local_tasks() in zen/template.php
  38   *
  39   *   For more information, please visit the Theme Developer's Guide on
  40   *   Drupal.org: http://drupal.org/node/173880
  41   *
  42   * CREATE OR MODIFY VARIABLES FOR YOUR THEME
  43   *
  44   *   Each tpl.php template file has several variables which hold various pieces
  45   *   of content. You can modify those variables (or add new ones) before they
  46   *   are used in the template files by using preprocess functions.
  47   *
  48   *   This makes THEME_preprocess_HOOK() functions the most powerful functions
  49   *   available to themers.
  50   *
  51   *   It works by having one preprocess function for each template file or its
  52   *   derivatives (called template suggestions). For example:
  53   *     THEME_preprocess_page    alters the variables for page.tpl.php
  54   *     THEME_preprocess_node    alters the variables for node.tpl.php or
  55   *                              for node-forum.tpl.php
  56   *     THEME_preprocess_comment alters the variables for comment.tpl.php
  57   *     THEME_preprocess_block   alters the variables for block.tpl.php
  58   *
  59   *   For more information on preprocess functions and template suggestions,
  60   *   please visit the Theme Developer's Guide on Drupal.org:
  61   *   http://drupal.org/node/223440
  62   *   and http://drupal.org/node/190815#template-suggestions
