  2.     File:        DocUtilP.cpp
  3.  
  4.     Contains:    Routines from DocUtils.cpp that are only used by the shell. They
  5.                 have been removed from DocUtils.cpp. DocUtils.cpp exposes
  6.                 private implementation of the shell, and we would like to
  7.                 remove the routines there from the public distribution.
