-     * A POSIX compliant, node based filesystem built on top of Myriad.
-     *
-     * A header is placed into stream 1.
-     * Header format:
-     *   int32_t iMagicHeader  (A7188B39)
-     *   int8_t iVersion (1)
-     *   int32_t iNumNodes
-     *   NodeLookup[iNumNodes] nNode
-     *
-     * Node lookup:
-     *   int32_t iInode
-     *   int32_t iPosition
-     *
-     * The node headers or inode structures have a base size of 44 bytes.
-     * The name is stored in the directory format.
-     * Basic node header format:
-     *   int32_t iNode
-     *   int32_t iUser
-     *   int32_t iGroup
-     *   uint16_t uPerms
-     *   int16_t iLinks
-     *   uint32_t uStreamIndex
-     *   int64_t iATime
-     *   int64_t iMTime
-     *   int64_t iCTime
-     *
-     * Some types get special formats for their assosiated data stream, or
-     * other special considerations, here's a list:
-     *
-     * - typeFifo: No stream, uStreamIndex unused (probably)
-     * - typeChrDev: No stream, uStreamIndex is device hi/lo
-     * - typeDir: The stream contains a directory contents listing, described
-     *            below
-     * - typeBlkDev: No stream, uStreamIndex is device hi/lo
-     * - typeRegFile: The stream is the file data
-     * - typeSymLink: The stream is the destination of the symlink
-     * - typeSocket: No steram, uStreamIndex unused (probably)
-     *
-     * Directory streams have this simple listing format.  They contain a list
-     * of all child elements, with no particular order at the moment.  The . and
-     * .. entries are not listed, they are implicit:
-     *   int32_t iNumNodes
-     *   NodeTable[iNumNodes] nChildren
-     *
-     * NodeTable:
-     *   int32_t iInode
-     *   uint8_t uNameSize
-     *   char[uNameSize] sName
