    _\bE_\bx_\bp_\bo_\br_\bt_\bs specifies remote mount points for the NFS mount pro-
    tocol per the NFS server specification; see ``Network File
    System Protocol Specification, RFC1094''.

    Each line in the file specifies one remote mount point.  The
    first field is the mount point directory path followed
    optionally by export options and specific hosts separated by
    white space.  Only the first entry for a given local file
    system may specify the export options, since these are han-
    dled on a _\bp_\be_\br _\bl_\bo_\bc_\ba_\bl _\bf_\bi_\bl_\be _\bs_\by_\bs_\bt_\be_\bm basis.  If no specific hosts
    are specified, the mount point is exported to all hosts.

    The export options are as follows: -\b-r\bro\boo\bot\bt=\b=<\b<u\bui\bid\bd>\b> specifies how
    to map root's uid (default -2).  The option -\b-r\br is synonyms
    for -\b-r\bro\boo\bot\bt in an effort to be backward compatible with older
    export file formats.

    -\b-r\bro\bo specifies that the file system should be exported Read-
    only (default Read/Write).  The option -\b-o\bo is synonyms for
    -\b-r\bro\bo in an effort to be backward compatible with older export
    file formats.

    For example:
         /usr -root=0 rickers snowhite.cis.uoguelph.ca
         /usr/local 131.104.48.16
         /u -root=5
         /u2 -ro

    given that /\b/u\bus\bsr\br, /\b/u\bu and /\b/u\bu2\b2 are local file system mount
    points, specifies the following:
         /\b/u\bus\bsr\br is exported to hosts _\br_\bi_\bc_\bk_\be_\br_\bs and
         _\bs_\bn_\bo_\bw_\bh_\bi_\bt_\be._\bc_\bi_\bs._\bu_\bo_\bg_\bu_\be_\bl_\bp_\bh._\bc_\ba with root mapped to root.
         /\b/u\bus\bsr\br/\b/l\blo\boc\bca\bal\bl is exported to host _\b1_\b3_\b1._\b1_\b0_\b4._\b4_\b8._\b1_\b6 with root
         mapped to root.
         /\b/u\bu is exported to all hosts with root mapped to uid 5.
         /\b/u\bu2\b2 is exported to all hosts Read-only with root mapped
         to -2.

    Note that /\b/u\bus\bsr\br/\b/l\blo\boc\bca\bal\bl -\b-r\bro\boo\bot\bt=\b=5\b5 would have been incorrect,
    since /\b/u\bus\bsr\br and /\b/u\bus\bsr\br/\b/l\blo\boc\bca\bal\bl reside in the same local file sys-
    tem.

    It would be nice if the export options were not tied to
    local mount points.
