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