function template_preprocess_maintenance_page

Process variables for maintenance-page.tpl.php.

The variables array generated here is a mirror of template_preprocess_page(). This preprocessor will run its course when theme_maintenance_page() is invoked. An alternate template file of maintenance-page--offline.tpl.php can be used when the database is offline to hide errors and completely replace the content.

The $variables array contains the following arguments:

• $content
