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.
