NAME
       srec_stewie - Stewie's binary file format

DESCRIPTION
       If you have a URL for documentation of this format, please let me know.

       Any  resemblance	 to  the Motorola S-Record is superficial, and extends
       only to the data	records.  The header records and  termination  records
       are  completely different.  None	of the other Motorola S-Records	record
       type are	available.

   The Records
       All records start with an ASCII capital S character, value  0x53,  fol-
       lowed by	a type specifier byte.	All records consist of binary bytes.

   The Header Record
       Each file starts	with a fixed four byte header record.

			     +-----+------+------+------+
			     |0x53 | 0x30 | 0x30 | 0x33	|
			     +-----+------+------+------+
   The Data Records
       Each data record	consists of 5 fields. These are	the type field,	length
       field, address field, data field, and the checksum.  The	 lines	always
       start with a capital S character.

	      +-----+------+---------------+---------+------+----------+
	      |0x53 | Type | Record Length | Address | Data | Checksum |
	      +-----+------+---------------+---------+------+----------+
       Type    The  type  field	is a one byte field that specifies whether the
	       record has a two-byte address field (0x31),  a  three-byte  ad-
	       dress  field  (0x32)  or	a four-byte address field (0x33).  The
	       address is big-endian.

       Record Length
	       The record length field is a one	byte field that	specifies  the
	       number of bytes in the record following this byte.

       Address This  is	 a  2-,	 3- or 4-byte address that specifies where the
	       data in the record is to	be loaded into memory.

       Data    The data	field contains the  executable	code,  memory-loadable
	       data or descriptive information to be transferred.

       Checksum
	       The checksum is a one byte field	that represents	the least sig-
	       nificant	byte of	the one's complement of	the sum	of the	values
	       represented  by	the  bytes  making up the record's length, ad-
	       dress, and data fields.

   The Termination Record
       Each file ends with a fixed two byte termination	record.

				    +-----+------+
				    |0x53 | 0x38 |
				    +-----+------+
   Size	Multiplier
       In general, binary data will expand in sized by approximately 1.2 times
       when represented	with this format.

EXAMPLE
       Here  is	 an  hex-dump  example	file.	It  contains  the data "Hello,
       World[rq] to be loaded at address 0.
	      0000: 53 30 30 33	53 31 10 00 00 48 65 6C	6C 6F 2C 20  S003S1...Hello,
	      0010: 57 6F 72 6C	64 0A 9D 53 38			     World..S8
