create_initial_taxonomies ( No parameters )
Defined at:
Codex:

Creates the initial taxonomies.

This function fires twice: in wp-settings.php before plugins are loaded (for backward compatibility reasons), and again on the {@see 'init'} action. We must avoid registering rewrite rules before the {@see 'init'} action.
