  64 #       The following sed script is commented here.
  65 #       The first three expressions in the sed script
  66 #       insures that we only have lines
  67 #       that contain file names and the external
  68 #       declarations associated with each file.
  69 #       The next two parts of the sed script put the pattern
  70 #       (in this case the file name) into the hold space
  71 #       and creates the "filename filename" lines and
  72 #       writes them out. The first part is for .o files,
  73 #       the second is for .o's in archives.
  74 #       The last 2 sections of code are exactly alike but
  75 #       they handle different external symbols, namely the
  76 #       symbols that are defined in the text section, data section, bss
  77 #       section or common symbols and symbols
  78 #       that are referenced but not defined in this file.
  79 #       A line containing the symbol (from the pattern space) and
  80 #       the file it is referenced in (from the hold space) is
  81 #       put into the pattern space.
  82 #       If its text, data, bss or common it is written out to the
  83 #       symbol definition (symdef) file, otherwise it was referenced
  84 #       but not declared in this file so it is written out to the
  85 #       symbol referenced (symref) file.
