-7z Format description (2.30 Beta 25)
------------------------------------
-
-This file contains description of 7z archive format. 
-7z archive can contain files compressed with any method.
-See "Methods.txt" for description for defined compressing methods.

-Notes about Notation and encoding
----------------------------------
-
-7z uses little endian encoding.
-
-7z archive format has optional headers that are marked as
-[]
-Header
-[]
-
-REAL_UINT64 means real UINT64.
-
-UINT64 means real UINT64 encoded with the following scheme:
-
-  Size of encoding sequence depends from first byte:
-  First_Byte  Extra_Bytes        Value
-  (binary)   
-  0xxxxxxx               : ( xxxxxxx           )
-  10xxxxxx    BYTE y[1]  : (  xxxxxx << (8 * 1)) + y
-  110xxxxx    BYTE y[2]  : (   xxxxx << (8 * 2)) + y
-  ...
-  1111110x    BYTE y[6]  : (       x << (8 * 6)) + y
-  11111110    BYTE y[7]  :                         y
-  11111111    BYTE y[8]  :                         y
