-- the GNAT tree packages (Atree, Sinfo, ...). It uses exactly the same global
-- variables as Errout, located in package Err_Vars. Like Errout, it also uses
-- the common variables and routines in package Erroutc.
+--
+-- Parameters are set through Err_Vars.Error_Msg_File_* or
+-- Err_Vars.Error_Msg_Name_*, and replaced automatically in the messages
+-- ("{{" for files, "%%" for names).
+--
+-- However, in this package you can configure the error messages to be sent
+-- to your own callback by setting Report_Error in the flags. This ensures
+-- that applications can control where error messages are displayed.
