23/* This file is part of NLM support for BFD, and contains the portions
24   that describe how NLM is represented externally by the BFD library.
25   I.E. it describes the in-file representation of NLM.  It requires
26   the nlm/common.h file which contains the portions that are common to
27   both the internal and external representations.
28
29   Note that an NLM header consists of three parts:
30
31   (1)  A fixed length header that has specific fields of known length,
32        at specific offsets in the file.
33
34   (2)  A variable length header that has specific fields in a specific
35        order, but some fields may be variable length.
36
37   (3)  A auxiliary header that has various optional fields in no specific
38        order.  There is no way to identify the end of the auxiliary headers
39        except by finding a header without a recognized 'stamp'.
40
41   The exact format of the fixed length header unfortunately varies
42   from one NLM target to another, due to padding.  Each target
43   defines the correct external format in a separate header file.  */
