  46    ---------------------------
  47
  48    --  GNAT requires that there be a one to one correspondence between source
  49    --  file names (as used in the Osint package interface) and unit names as
  50    --  defined by the Uname package. This correspondence is defined by the
  51    --  two subprograms defined here in the Fname package.
  52
  53    --   For full rules of file naming, see GNAT User's Guide. Note that the
  54    --   naming rules are affected by the presence of Source_File_Name pragmas
  55    --   that have been previously processed.
  56
  57    --  Note that the file name does *not* include the directory name. The
  58    --  management of directories is provided by Osint, and full file names
  59    --  are used only for error message purposes within GNAT itself.
