option to set the attributes of the newly created section.
@item --dump-section @var{sectionname}=@var{filename}
Place the contents of section named @var{sectionname} into the file
@var{filename}, overwriting any contents that may have been there

as raw binary data, without applying any relocations. The option can
be specified more than once.
@item --rename-section @var{oldname}=@var{newname}[,@var{flags}]
Rename a section from @var{oldname} to @var{newname}, optionally
