Process theme data.

Use this file to run your theme specific implimentations of theme functions, such preprocess, process, alters, and theme function overrides.

Preprocess and process functions are used to modify or create variables for templates and theme functions. They are a common theming tool in Drupal, often used as an alternative to directly editing or adding code to templates. Its worth spending some time to learn more about these functions - they are a powerful way to easily modify the output of any template variable.

Preprocess and Process Functions SEE: http://drupal.org/node/254940#variables-processor 1. Rename each function and instance of "adaptivetheme_subtheme" to match your subthemes name, e.g. if your theme name is "footheme" then the function name will be "footheme_preprocess_hook". Tip - you can search/replace on "adaptivetheme_subtheme". 2. Uncomment the required function to use.
