-/**
- * Protocol version 2.0 description
- *
- * The following table shows the exact assembly of the 2.0 protocol.
- *
- * -->Header<--
- * The protocol header is always send first, and contains various
- * information about the data block to come.
- * The header is always of fixed length, and will be send unencrypted.
- *
- * Byte Number/Bytes Description
- * 00-02 Contains always the string "V2."
- * 03 This byte contains a possible subrelease number of the
- * protocol. This enables the receiver to make a version
- * check to ensure the compatibility and allows us to
- * release 2.x versions of the protocol with bugfixes or
- * enhancements.
- * 04 This byte is reserved for possible future extensions.
- * 05 Usually, this byte contains the character '0'. If the
- * VFS module is configured for encryption of the data,
- * this byte is set to 'E'.
- * 06-09 These bytes contain the character '0' by default, and
- * are reserved for possible future extensions. They have
- * no function in 2.0.
- * 10-27 17 bytes containing a string representation of the
- * number of bytes to come in the following data block.
- * It is right aligned and filled from the left with '0'.
- *
- * -->Data Block<--
- * The data block is send immediately after the header was send. It's length
- * is exactly what was given in bytes 11-28 from in the header.
- *
- * The data block may be send encrypted.
- *
- * To make the data block easy for the receiver to read, it is divided into
- * several sub-blocks, each with it's own header of four byte length. In each
- * of the sub-headers, a string representation of the length of this block is
- * to be found.
- *
- * Thus the formal structure is very simple:
- *
- * [HEADER]data[HEADER]data[HEADER]data[END]
- *
- * whereas [END] is exactly at the position given in bytes 11-28 of the
- * header.
- *
- * Some data the VFS module is capturing is of use for any VFS operation.
- * Therefore, there is a "common set" of data, that will be send with any
- * data block. The following provides a list of this data.
- * - the VFS function identifier (see VFS function ifentifier table below).
- * - a timestamp to the millisecond.
- * - the username (as text) who runs the VFS operation.
- * - the SID of the user who run the VFS operation.
- * - the domain under which the VFS operation has happened.
