        !             3: dmsdosd \- dmsdos daemon for background compression
        !             4: .SH SYNOPSIS
        !             5: 
        !             6: .BI dmsdosd " directory [level [debug]]"

        !             8: .SH DESCRIPTION
        !             9: .I dmsdosd 
        !            10: does compression for the dmsdos driver in the background when
        !            11: the system is idle. This may reduce system load when there are much data
        !            12: to compress because the dmsdos driver can leave the data as they are and
        !            13: pass them to the daemon to do the job of compression.
        !            14: .I directory
        !            15: must be the mountpoint of a CVF that is served by dmsdos.
        !            16: In fact,
        !            17: .I directory
        !            18: may be also a subdirectory of the mountpoint. (If you mount more than
        !            19: one dmsdos partition it doesn't matter which one you specify. There is
        !            20: also no need to restart the daemon when additional partitions are mounted -
        !            21: the daemon automatically handles them all.)
        !            22: 
        !            23: .I level
        !            24: is the compression level. It must be in the range of
        !            25: .BR 1 " - " 12 .
        !            26: If no
        !            27: .I level
        !            28: is given, it defaults to 12.
        !            29: 
        !            30: If the parameter
        !            31: .I debug
        !            32: is given, dmsdosd prints a lot of debug information to stderr and doesn't
        !            33: put itself into the background.
        !            34: 
        !            35: Note that you must run
        !            36: .I dmsdosd
        !            37: as root. The daemon refuses to run if started by another user. It also
        !            38: doesn't start if it finds already one instance of
        !            39: .I dmsdosd
        !            40: running.
        !            41: 
        !            42: You can kill the daemon at any time (even when it is under heavy work).
        !            43: Send a SIGINT to let the daemon finish its actual work and then exit.
        !            44: Send a SIGTERM to make the daemon exit as soon as possible. You should not 
        !            45: send a SIGKILL.

        !            48: .I dmsdosd 
        !            49: can only be started when a CVF has already been mounted by the
        !            50: dmsdos driver. 
        !            51: 
        !            52: You must kill 
        !            53: .I dmsdosd
        !            54: before you can unmount the CVF that was given in the command line.
        !            55: 
        !            56: Older versions (below 0.9.0.12) didn't run in the background, didn't check 
        !            57: for already running processes and didn't use stderr for error and debug
        !            58: messages. This manual page is not valid for them.
