   "@brief An object that represents an interior space.\n\n"

   "A zone is an invisible volume that encloses an interior space.  All objects that have "
   "their world space axis-aligned bounding boxes (AABBs) intersect the zone's volume are "
   "assigned to the zone.  This assignment happens automatically as objects are placed "
   "and transformed.  Also, assignment is not exclusive meaning that an object can be assigned "
   "to many zones at the same time if it intersects all of them.\n\n"

   "In itself, the volume of a zone is fully sealed off from the outside.  This means that while "
   "viewing the scene from inside the volume, only objects assigned to the zone are rendered while "
   "when viewing the scene from outside the volume, objects <em>exclusively</em> only assigned the "
   "zone are not rendered.\n\n"

   "Usually, you will want to connect zones to each other by means of portals.  A portal overlapping "
   "with a zone \n\n"

   "@tsexample\n"
   "// Example declaration of a Zone.  This creates a box-shaped zone.\n"
   "new Zone( TestZone )\n"
   "{\n"
   "   position = \"3.61793 -1.01945 14.7442\";\n"

   "   scale = \"10 10 10\";\n"
   "};\n"
   "@endtsexample\n\n"

   "@section Zone_zoneGroups Zone Groups\n\n"

   "Normally, Zones will not connect to each other when they overlap.  This means that if viewing "
   "the scene from one zone, the contents of the other zone will not be visible except when there "
   "is a portal connecting the zones.  However, sometimes it is convenient to represent a single interior "
   "space through a combination of Zones so that when any of these zones is visible, all other zones "
   "that are part of the same interior space are visible.  This is possible by employing \"zone groups\".\n\n"
