+.Os
+.Sh NAME
+.Nm mount_reiserfs
+.Nd mount a ReiserFS file system
+.Sh SYNOPSIS
+.Nm
+.Pa special
+.Pa node
+.Sh DESCRIPTION
+The
+.Nm
+utility attaches the ReiserFS file system residing on the device
+.Pa special
+to the global file system namespace at the location
+indicated by
+.Pa node .
+.Pp
+This command is normally executed by
+.Xr mount 8
+at boot time, but can be used by any user to mount a
+ReiserFS file system on any directory that they own (provided,
+of course, that they have appropriate access to the device that
+contains the file system).
+.Sh EXAMPLES
+To mount a ReiserFS volume located in
+.Pa /dev/ad1s1 :
+.Pp
+.Dl "mount_reiserfs /dev/ad1s1 /mnt"
+.Sh SEE ALSO
+.Xr mount 2 ,
+.Xr unmount 2 ,
+.Xr fstab 5 ,
+.Xr mount 8
+.Sh CAVEATS
+This utility is primarily used for read access to a ReiserFS volume.
+Writing to a volume is currently unsupported.
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Fx 6.0 .
+.Sh AUTHORS
+The ReiserFS kernel implementation was written by
+.An Hans Reiser (http://www.namesys.com/) ,
+and ported to
+.Fx
+by
+.An Jean-Sébastien Pédron <dumbbell@FreeBSD.org> .
+.Pp
+The
+.Nm
+utility and manual were written by
+.An Jean-Sébastien Pédron <dumbbell@FreeBSD.org> .
