function template_preprocess_page

Preprocess variables for page.tpl.php

Most themes utilize their own copy of page.tpl.php. The default is located inside "modules/system/page.tpl.php". Look in there for the full list of variables.

Uses the arg() function to generate a series of page template suggestions based on the current path.

Any changes to variables in this preprocessor should also be changed inside template_preprocess_maintenance_page() to keep all of them consistent.
