2 the unpacking manifest is a structure defined in terms of bytes.
3 the exe's manifest offset is set to point to the beginning of this structure.
7 0 => 3 number of chunks in the TOC
8 4 => 4+N-1 first manifest item, with length N
9 4+N => 4+N+M-1 second item, with length M
12 each bundle chunk has a structure:
16 0 => 3 size of the data component of the chunk
17 4 => 4+S-1 the file system target location for this chunk, as a zero
18 terminated string (of length S). this string comes from the
19 target defined in the packing manifest.
21 then the data starts after the end of the TOC; each chunk occupies the space
22 declared for it in the manifest.
