  27 --  This package contains the routines to output error messages and the
  28 --  scanner for the project files. It replaces Errout and Scn.
  29 --  It is not dependent on the GNAT tree packages (Atree, Sinfo, ...).
  30 --  It uses the same global variables as Errout, located in package
  31 --  Err_Vars. Like Errout, it also uses the common variables and routines
  32 --  in package Erroutc.
