  27 --  This child package contains the routines to translate a unit name to
  28 --  a file name taking into account Source_File_Name pragmas. It also
  29 --  contains the auxiliary routines used to record data from the pragmas.
  30
  31 --  Note: the reason we split this into a child unit is that the routines
  32 --  for unit name translation have a significant number of additional
  33 --  dependencies, including osint, and hence sdefault. There are a number
  34 --  of tools that use utility subprograms in the Fname parent, but do not
  35 --  need the functionality in this child package (and certainly do not want
  36 --  to deal with the extra dependencies).
