 173
 174    The original set of symbolic information in the symtab_command which contains
 175    the symbol and string tables must also be present when this load command is
 176    present.  When this load command is present the symbol table is organized
 177    into three groups of symbols:
 178        local symbols (static and debugging symbols) - grouped by module
 179        defined external symbols - grouped by module (sorted by name if not lib)
 180        undefined external symbols (sorted by name)
 181    In this load command there are offsets and counts to each of the three groups
 182    of symbols.
 183
 184    This load command contains a the offsets and sizes of the following new
 185    symbolic information tables:
 186        table of contents
 187        module table
 188        reference symbol table
 189        indirect symbol table
 190    The first three tables above (the table of contents, module table and
 191    reference symbol table) are only present if the file is a dynamically linked
 192    shared library.  For executable and object modules, which are files
 193    containing only one module, the information that would be in these three
 194    tables is determined as follows:
 195        table of contents - the defined external symbols are sorted by name
 196        module table - the file contains only one module so everything in the
 197                       file is part of the module.
 198        reference symbol table - is the defined and undefined external symbols
 199
 200    For dynamically linked shared library files this load command also contains
 201    offsets and sizes to the pool of relocation entries for all sections
 202    separated into two groups:
 203        external relocation entries
 204        local relocation entries
 205    For executable and object modules the relocation entries continue to hang
 206    off the section structures.  */
