   4  * \brief Header: Low-level protocol for MCFS
   5  *
   6  * \todo FIXME: This protocol uses 32-bit integers for the communication.
   7  * It is a problem on systems with large file support, which is now
   8  * default. This means that lseek is broken unless --disable-largefile
   9  * is used. 64-bit systems are probably broken even more.
