 Class
-    Foam::writeFuns
+    Foam::vtkWriteOps
 
 Description
-    Various functions for collecting and writing binary data.
-
-    The LITTLE_ENDIAN is based on 32bit words.
-    It is not clear how 64bit labels should be handled, currently they are
-    split into two 32bit words and swapWord applied to these two.
-
-    writeFuns should be a namespace rather than a class.
+    VTK ASCII and binary write functions
