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