Extending Semiologic Pro Features
=================================


1. Registering features
-----------------------

add to the skin.php or custom.php file:

	sem_features::register($feature_sets);

where:

	$feature_sets = array(
		'feature_set_key1' => array (
			'feature_key1',
			'feature_key2',
			),
		'feature_set_key2' => array
			(
			'feature_key3',
			'feature_key4',
			)
		);



2. Registering feature handlers
-------------------------------

add to the skin.php or custom.php file:

	sem_pro_features::register(
		$feature_key,
		$plugin_file,
		$activate,
		$deactivate,
		$is_enabled,
		);

where:

- $feature_key is the feature's key
- $plugin_files is a plugin file, e.g. 'my_plugin.php' (optional, can also be an array of files)
- $activate is a callback function that gets called when you activate (optional)
- $deactivate is a callback function that gets called when you deactivate (optional)
- $is_enabled is a callback function that gets called when you check if the feature is active (optional)


3. Extending docs
-----------------

add to a skin.php or custom.php file:

	function extend_docs($sem_docs)
	{
		$sem_docs['feature_sets'][$key] = array(
			'name' => $name,
			'excerpt' => $excerpt,
			'content' => $content,
			);

		$sem_docs['features'][$key] = array(
			'name' => $name,
			'excerpt' => $excerpt,
			'content' => $content,
			);

		return $sem_docs;
	} # extend_docs

	add_filter('options_sem_docs', 'extend_docs');

where the variables are self-explanatory
