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