+/**
+ * Implementation of hook_requirements().
+ *
+ * @return
+ *   An array describing the status of the site regarding available updates.
+ *   If there is no update data, only one record will be returned, indicating
+ *   that the status of core can't be determined. If data is available, there
+ *   will be two records: one for core, and another for all of contrib
+ *   (assuming there are any contributed modules or themes enabled on the
+ *   site). In addition to the fields expected by hook_requirements ('value',
+ *   'severity', and optionally 'description'), this array will contain a
+ *   'reason' attribute, which is an integer constant to indicate why the
+ *   given status is being returned (UPDATE_NOT_SECURE, UPDATE_NOT_CURRENT, or
+ *   UPDATE_UNKNOWN). This is used for generating the appropriate e-mail
+ *   notification messages during update_cron(), and might be useful for other
+ *   modules that invoke update_requirements() to find out if the site is up
+ *   to date or not.
+ *
+ * @see _update_message_text()
