       The xxppoorrtt function's main purpose is to write an XML formatted
       representation of the data stored in one or several RRRRDDs. It can also
       extract numerical reports.

       If no _X_P_O_R_T statements are found, there will be no output.

       --ss|----ssttaarrtt _s_e_c_o_n_d_s (default end-1day)
           The time when the exported range should begin. Time in seconds
           since epoch (1970-01-01) is required. Negative numbers are relative
           to the current time. By default one day worth of data will be
           printed.  See also AT-STYLE TIME SPECIFICATION section in the
           _r_r_d_f_e_t_c_h documentation for a detailed explanation on how to specify
           time.

       --ee|----eenndd _s_e_c_o_n_d_s (default now)
           The time when the exported range should end. Time in seconds since
           epoch.  See also AT-STYLE TIME SPECIFICATION section in the
           _r_r_d_f_e_t_c_h documentation for a detailed explanation of ways to
           specify time.

       --mm|----mmaaxxrroowwss _r_o_w_s (default 400 rows)
           This works like the --ww|----wwiiddtthh parameter of _r_r_d_g_r_a_p_h.  In fact it
           is exactly the same, but the parameter was renamed to describe its
           purpose in this module. See _r_r_d_g_r_a_p_h documentation for details.

       ----sstteepp _v_a_l_u_e (default automatic)
           See rrdgraph documentation.

       ----eennuummddss
           The generated xml should contain the data values in enumerated
           tags.

            <v0>val</v0><v1>val</v1>

       DDEEFF::_v_n_a_m_e==_r_r_d::_d_s_-_n_a_m_e::_C_F
           See _r_r_d_g_r_a_p_h documentation.

       CCDDEEFF::_v_n_a_m_e==_r_p_n_-_e_x_p_r_e_s_s_i_o_n
           See _r_r_d_g_r_a_p_h documentation.

       XXPPOORRTT::_v_n_a_m_e::::_l_e_g_e_n_d
           At least one _X_P_O_R_T statement should be present. The values
           referenced by _v_n_a_m_e are printed. Optionally add a legend.

       The output is enclosed in an xxppoorrtt element and contains two blocks. The
       first block is enclosed by a mmeettaa element and contains some meta data.
       The second block is enclosed by a ddaattaa element and contains the data
       rows.

       Let's assume that the _x_p_o_r_t command looks like this:

         rrdtool xport \
                 --start now-1h --end now \
                 DEF:xx=host-inout.lo.rrd:output:AVERAGE \
                 DEF:yy=host-inout.lo.rrd:input:AVERAGE \
                 CDEF:aa=xx,yy,+,8,* \
                 XPORT:xx:"out bytes" \
                 XPORT:aa:"in and out bits"

       The resulting meta data section is (the values will depend on the RRD
       characteristics):

         <meta>
           <start>1020611700</start>
           <step>300</step>
           <end>1020615600</end>
           <rows>14</rows>
           <columns>2</columns>
           <legend>
             <entry>out bytes</entry>
             <entry>in and out bits</entry>
           </legend>
         </meta>

       The resulting data section is:
