     - mesh with cells put into cellZones (-makeCellZones)
 
     Note:
-    - Should work in parallel but cellZone interfaces cannot align with
-    processor boundaries so use the correct option in decomposition to
-    preserve those interfaces.
+    - Should work in parallel.
+    cellZones can differ on either side of processor boundaries in which case
+    the faces get moved from processor patch to directMapped patch. Not

     - If a cell zone gets split into more than one region it can detect
     the largest matching region (-sloppyCellZones). This will accept any
     region that covers more than 50% of the zone. It has to be a subset
