/**
 * Convenience function to display large blocks of text in several places.
 *
 * There are many instances where Ubercart modules have configurable blocks of
 * text. These usually come with default messages, like e-mail templates for new
 * orders. Because of the way default values are normally set, you're then stuck
 * having to copy and paste a large chunk of text in at least two different
 * places in the module (when you're wanting to use the variable or to display
 * the settings form with the default value). To cut down code clutter, this
 * hook was introduced. It lets you put your messages in one place and use the
 * function uc_get_message() to retrieve the default value at any time (and from
 * any module).
 *
 * The function is very simple, expecting no arguments and returning a basic
 * associative array with keys being message IDs and their values being the
 * default message. When you call uc_get_message(), use the message ID you set
 * here to refer to the message you want.
 *
 * Note: When using t(), you must not pass it a concatenated string! So our
 * example has no line breaks in the message even though it is much wider than
 * 80 characters. Using concatenation breaks translation.
 *
 * @return
 *   An array of messages.
 */
function hook_uc_message() {
  $messages['configurable_message_example'] = t('This block of text represents a configurable message such as a set of instructions or an e-mail template.  Using hook_uc_message to handle the default values for these is so easy even your grandma can do it!');
  return $messages;
}

/**
 * Adds status messages to the "Store administration" page.
 *
 * This hook is used to add items to the store status table on the main store
 * administration screen. Each item gets a row in the table that consists of a
 * status icon, title, and description. These items should be used to give
 * special instructions, notifications, or indicators for components of the cart
 * enabled by the modules. At a glance, a store owner should be able to look
 * here and see if a critical component of your module is not functioning
 * properly.
 *
 * For example, if the catalog module is installed and it cannot find the
 * catalog taxonomy vocabulary, it will show an error message here to alert the
 * store administrator.
 *
 * @return
 *   An array of store status items which are arrays with the following keys:
 *   - status: "ok", "warning", or "error" depending on the message.
 *   - title: The title of the status message or module that defines it.
 *   - desc: The description; can be any message, including links to pages and
 *     forms that deal with the issue being reported.
