Chris@0:  * ABOUT THE TEMPLATE.PHP FILE
Chris@0:  *
Chris@0:  *   The template.php file is one of the most useful files when creating or
Chris@0:  *   modifying Drupal themes. You can add new regions for block content, modify
Chris@0:  *   or override Drupal's theme functions, intercept or make additional
Chris@0:  *   variables available to your theme, and create custom PHP logic. For more
Chris@0:  *   information, please visit the Theme Developer's Guide on Drupal.org:
Chris@0:  *   http://drupal.org/theme-guide
Chris@0:  *
Chris@0:  * OVERRIDING THEME FUNCTIONS
Chris@0:  *
Chris@0:  *   The Drupal theme system uses special theme functions to generate HTML
Chris@0:  *   output automatically. Often we wish to customize this HTML output. To do
Chris@0:  *   this, we have to override the theme function. You have to first find the
Chris@0:  *   theme function that generates the output, and then "catch" it and modify it
Chris@0:  *   here. The easiest way to do it is to copy the original function in its
Chris@0:  *   entirety and paste it here, changing the prefix from theme_ to STARTERKIT_.
Chris@0:  *   For example:
Chris@0:  *
Chris@0:  *     original: theme_breadcrumb()
Chris@0:  *     theme override: STARTERKIT_breadcrumb()
Chris@0:  *
Chris@0:  *   where STARTERKIT is the name of your sub-theme. For example, the
Chris@0:  *   zen_classic theme would define a zen_classic_breadcrumb() function.
Chris@0:  *
Chris@0:  *   If you would like to override any of the theme functions used in Zen core,
Chris@0:  *   you should first look at how Zen core implements those functions:
Chris@0:  *     theme_breadcrumbs()      in zen/template.php
Chris@0:  *     theme_menu_item_link()   in zen/template.php
Chris@0:  *     theme_menu_local_tasks() in zen/template.php
Chris@0:  *
Chris@0:  *   For more information, please visit the Theme Developer's Guide on
Chris@0:  *   Drupal.org: http://drupal.org/node/173880
Chris@0:  *
Chris@0:  * CREATE OR MODIFY VARIABLES FOR YOUR THEME
Chris@0:  *
Chris@0:  *   Each tpl.php template file has several variables which hold various pieces
Chris@0:  *   of content. You can modify those variables (or add new ones) before they
Chris@0:  *   are used in the template files by using preprocess functions.
Chris@0:  *
Chris@0:  *   This makes THEME_preprocess_HOOK() functions the most powerful functions
Chris@0:  *   available to themers.
Chris@0:  *
Chris@0:  *   It works by having one preprocess function for each template file or its
Chris@0:  *   derivatives (called template suggestions). For example:
Chris@0:  *     THEME_preprocess_page    alters the variables for page.tpl.php
Chris@0:  *     THEME_preprocess_node    alters the variables for node.tpl.php or
Chris@0:  *                              for node-forum.tpl.php
Chris@0:  *     THEME_preprocess_comment alters the variables for comment.tpl.php
Chris@0:  *     THEME_preprocess_block   alters the variables for block.tpl.php
Chris@0:  *
Chris@0:  *   For more information on preprocess functions and template suggestions,
Chris@0:  *   please visit the Theme Developer's Guide on Drupal.org:
