+ Mini symbols
+
+ Mini symbols provide read-only access to the symbol table.
+ They use less memory space, but require more time to access.
+ They can be useful for tools like nm or objdump, which may
+ have to handle symbol tables of extremely large executables.
+
+ The <<bfd_read_minisymbols>> function will read the symbols
+ into memory in an internal form. It will return a <<void *>>
+ pointer to a block of memory, a symbol count, and the size of
+ each symbol. The pointer is allocated using <<malloc>>, and
+ should be freed by the caller when it is no longer needed.
+
+ The function <<bfd_minisymbol_to_symbol>> will take a pointer
+ to a minisymbol, and a pointer to a structure returned by
+ <<bfd_make_empty_symbol>>, and return a <<asymbol>> structure.
+ The return value may or may not be the same as the value from
+ <<bfd_make_empty_symbol>> which was passed in.
