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