**********************************************
* QuickTime 5 Install/Archive Package Format *
**********************************************
- values use big endian (network) byte order
- general terms: integer = signed value
- general values: byte/char/octet = 8-bit value ; short/word = 16-bit value ;
long = 32-bit value
- binary values: base-2 long unsigned values (values from 0 and 1)
- octal values: base-8 long unsigned values (values from 0 through to 7)
- decimal values: base-10 long unsigned values (values from 0 through to 9)
- hexadecimal (hex) values: base-16 long unsigned values
(values from 0 to 9 and A to F)
- atom offsets: values relative to atoms only
and are used to skip to the next atom
- long mac file version: byte hex version + byte hex revision
+ byte hex revision stage + byte hex non-final number
- mac version revision stages: development = 0x20 ; alpha = 0x40 ;
beta = 0x60 ; release = 0x80
FILE INFO
Suffix = ".pkg" ; Mac OS Type = "pack" ; Mac OS Creator = "qtup" ;
MIME="application/x-quicktime-install-package"
Standard single fork binary file that only uses a resource fork on HFS/HFS+ volumes
to store mac specific file info.
Unknown atoms can be safely skipped over, atoms can be in any order, all
lowercase long ASCII text strings used for atom names/types are reserved for
use by Apple and packages can contain multiple file atoms.
The format is limited to a total size of 2^32 bytes (< 4.3 GB).
