- * @file llworld.h
- * @brief Collection of viewer regions in the vacinity of the user.
- *
- * Represents the whole world, so far as 3D functionality is conserned.
- * Always contains the region that the user's avatar is in along with
- * neighboring regions. As the user crosses region boundaries, new
- * regions are added to the world and distant ones are rolled up.
