Binutils is supposed to use tabs.

containing only one module, the information that would be in these three

table of contents - the defined external symbols are sorted by name
|
|
module table - the file contains only one module so everything in the
|
|
file is part of the module.
|
|
reference symbol table - is the defined and undefined external symbols
|
|
|
|
For dynamically linked shared library files this load command also contains
|
|
offsets and sizes to the pool of relocation entries for all sections
|
