+--  This child package contains the routines to translate a unit name to
+--  a file name taking into account Source_File_Name pragmas. It also
+--  contains the auxiliary routines used to record data from the pragmas.
+
+--  Note: the reason we split this into a child unit is that the routines
+--  for unit name translation have a significant number of additional
+--  dependencies, including osint, and hence sdefault. There are a number
+--  of tools that use utility subprograms in the Fname parent, but do not
+--  need the functionality in this child package (and certainly do not want
+--  to deal with the extra dependencies).

+
+   function File_Name_Of_Spec (Name : Name_Id) return File_Name_Type;
