By way of example with the addition of Ubuntu 19.04


(1) New .rpc files for each pair (one for each codebase)

  cp release_15p5_ubuntu_18p4.rpc release_15p5_ubuntu_19p4.rpc
  cp release_17p7_ubuntu_18p4.rpc release_17p7_ubuntu_19p4.rpc
  cp release_19p8_ubuntu_18p4.rpc release_14p7_ubuntu_19p4.rpc
  cp trunk_ubuntu_18p4.rpc trunk_ubuntu_19p4.rpc

(2) Create a new row file for the new codebase

    cp sys_lnx_ubuntu1804.rpc sys_lnx_ubuntu1904.rpc

(3) Edit the page_list.txt file

    add the four new pairs file
    add the new row file

    Note the row file will just ensure the two BuildRes.* tables will
    be built, e.g, 

        BuildRes.LNXUbuntu1904
        BuildRes.LNXUbuntu1904Brief

    The BuildTest.Ubuntu19p4 still needs to be build by hand on the serve

(4) Edit the dashboard.txt file
    Add the line for the new row

(5) On oceanai, create a new Row BuildTest file:

   $ cd /home/web/moos-ivp/pmwiki/wiki.d
   $ cp BuildTest.Ubuntu18p4 BuildTest.Ubuntu19p4
   then edit, commit the file to version control

(6) In project-vandv/bin/super_build.sh, Part 8:
    elif [[ "${OS}" == *Ubuntu-20.10* ]] ; then
       SUFFIX="_ubu_2010"
