  19 // This header assigns a level implemenation trait to a collection type
  20 // for all primitives.  It is needed so that archives which are meant to be
  21 // portable don't write class information in the archive.  Since, not all
  22 // compiles recognize the same set of primitive types, the possibility
  23 // exists for archives to be non-portable if class information for primitive
  24 // types is included.  This is addressed by the following macros.
