 /**
- * Declares information about actions.
- *
- * Any module can define actions, and then call actions_do() to make those
- * actions happen in response to events.
- *
- * An action consists of two or three parts:
- * - an action definition (returned by this hook)
- * - a function which performs the action (which by convention is named
- *   MODULE_description-of-function_action)
- * - an optional form definition function that defines a configuration form
- *   (which has the name of the action function with '_form' appended to it.)
- *
- * The action function takes two to four arguments, which come from the input
- * arguments to actions_do().
- *
- * @return
- *   An associative array of action descriptions. The keys of the array
- *   are the names of the action functions, and each corresponding value
- *   is an associative array with the following key-value pairs:
- *   - 'type': The type of object this action acts upon. Core actions have types
- *     'node', 'user', 'comment', and 'system'.
- *   - 'label': The human-readable name of the action, which should be passed
- *     through the t() function for translation.
- *   - 'configurable': If FALSE, then the action doesn't require any extra
- *     configuration. If TRUE, then your module must define a form function with
- *     the same name as the action function with '_form' appended (e.g., the
- *     form for 'node_assign_owner_action' is 'node_assign_owner_action_form'.)
- *     This function takes $context as its only parameter, and is paired with
- *     the usual _submit function, and possibly a _validate function.
- *   - 'triggers': An array of the events (that is, hooks) that can trigger this
- *     action. For example: array('node_insert', 'user_update'). You can also
- *     declare support for any trigger by returning array('any') for this value.
- *   - 'behavior': (optional) A machine-readable array of behaviors of this
- *     action, used to signal additionally required actions that may need to be
- *     triggered. Modules that are processing actions should take special care
- *     for the "presave" hook, in which case a dependent "save" action should
