 262    into three groups of symbols:
 263        local symbols (static and debugging symbols) - grouped by module
 264        defined external symbols - grouped by module (sorted by name if not lib)
 265        undefined external symbols (sorted by name)
 266    In this load command there are offsets and counts to each of the three groups
 267    of symbols.

 271        table of contents
 272        module table
 273        reference symbol table
 274        indirect symbol table
 275    The first three tables above (the table of contents, module table and
 276    reference symbol table) are only present if the file is a dynamically linked
 277    shared library.  For executable and object modules, which are files
 278    containing only one module, the information that would be in these three
 279    tables is determined as follows:
 280        table of contents - the defined external symbols are sorted by name
 281        module table - the file contains only one module so everything in the
 282                       file is part of the module.
 283        reference symbol table - is the defined and undefined external symbols
 284
 285    For dynamically linked shared library files this load command also contains
 286    offsets and sizes to the pool of relocation entries for all sections
 287    separated into two groups:
 288        external relocation entries
