        !            25: .B /etc/exports
        !            26: .SH DESCRIPTION
        !            27: .I Exports
        !            28: specifies remote mount points for the
        !            29: .SM NFS
        !            30: mount protocol per the
        !            31: .SM NFS
        !            32: server specification; see
        !            33: ``Network File System Protocol Specification, RFC1094''.
        !            34: .LP
        !            35: Each line in the file specifies one remote mount point.
        !            36: The first field is the mount point directory path followed
        !            37: optionally by export options and specific hosts separated by white space.
        !            38: Only the first entry for a given local file system may specify the export
        !            39: options, since these are handled on a \fIper local file system\fR basis.
        !            40: If no specific hosts are specified,
        !            41: the mount point is exported to all hosts.
        !            42: .LP
        !            43: The export options are as follows:
        !            44: .B \-root=<uid>
        !            45: specifies how to map root's uid (default -2).
        !            46: The option \fB\-r\fR is synonyms for \fB\-root\fP
        !            47: in an effort to be backward compatible with older export file formats.
        !            48: .sp
        !            49: .B \-ro
        !            50: specifies that the file system should be exported Read-only
        !            51: (default Read/Write).
        !            52: The option \fB-o\fR is synonyms for \fB\-ro\fP
        !            53: in an effort to be backward compatible with older export file formats.
        !            54: .LP
        !            55: For example:
        !            56: .RS
        !            57: /usr -root=0 rickers snowhite.cis.uoguelph.ca
        !            58: .br
        !            59: /usr/local 131.104.48.16
        !            60: .br
        !            61: /u -root=5
        !            62: .br
        !            63: /u2 -ro
        !            64: .RE
        !            65: .sp
        !            66: given that \fB/usr\fR, \fB/u\fR and \fB/u2\fR are
        !            67: local file system mount points, specifies the following:
        !            68: .RS
        !            69: \fB/usr\fR
        !            70: is exported to hosts \fIrickers\fR and \fIsnowhite.cis.uoguelph.ca\fR with
        !            71: root mapped to root.
        !            72: .br
        !            73: \fB/usr/local\fR
        !            74: is exported to host \fI131.104.48.16\fR with root mapped to root.
        !            75: .br
        !            76: \fB/u\fR
        !            77: is exported to all hosts with root mapped to uid 5.
        !            78: .br
        !            79: \fB/u2\fR
        !            80: is exported to all hosts Read-only with root mapped to -2.
        !            81: .RE
        !            82: .LP
        !            83: Note that \fB/usr/local -root=5\fR would have been incorrect,
        !            84: since \fB/usr\fR and \fB/usr/local\fR reside in the same local file system.
