 /**
- * Returns TRUE if the user is currently viewing the dashboard.

+ *
+ * This function checks if the user is currently viewing the dashboard and has

+ * decide whether or not the dashboard content should be displayed to the
+ * current user.
+ *
+ * Although the menu system normally handles the above tasks, it only does so
+ * for the main page content. However, the dashboard is not part of the main
+ * page content, but rather is displayed in special regions of the page (so it
+ * can interface with the Block module's method of managing page regions). We
+ * therefore need to maintain this separate function to check the menu item for
+ * us.

+ *   TRUE if the dashboard should be visible on the current page, FALSE
+ *   otherwise.
