Thanks, v8 uses that format. v8 will be the core, the hookup into the stack recording path, the statistics file, the documentation and the basic selftest, with your comments on 01-03 addressed. The binary export will carry the generation in its header, so I would like the core and the cookie format to settle first; the binary export, its parser and the capacity boot parameter will follow as a separate series. If you would rather have them in the same series, I can include them. So there is no need to look at 04-10 of v7. Thanks, Pengfei Li
