  Description
 
  The ostream_withassign class is a variant of ostream that allows object
  assignment. The predefined objects cout, cerr, and clog are objects of
  this class and thus may be reassigned at run time to a different ostream
  object.
 
  A program that normally sends output to stdout, for example, could be
  temporarily directed to send its output to a disk file.
 
  Predefined Objects
 
  There are three predefined objects of class ostream_withassign. They are
  connected as follows:
 
  cout   Standard output (file descriptor 1).
 
  cerr   Unit buffered standard error (file descriptor 2).
 
  clog   Fully buffered standard error (file descriptor 2).
 
  Unit buffering, as used by cerr, means that characters are flushed after
  each insertion operation. The objects cin, cerr, and clog are tied to
  cout so that use of any of these will cause cout to be flushed.
