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