+ If a binary contains object files for multiple architectures (e.g. it is a
+ Mach-O universal binary), symbolize the object file for a given architecture.
+ You can also specify architecture by writing ``binary_name:arch_name`` in the
+ input (see example above). If architecture is not specified in either way,
