(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.
