    // is to put the icns file into resources and associate it with the
    // application as here. I have also left it in the .pro file, as instructed
    // by Qt, as well as manually adding a reference to it in the plist.info.

    // Later: This only works while the program is actually running. The icon
    // that appears in the dock after the program has been closed is the
    // default icon, so clearly there is something wrong with the configuration
    // that will need to be sorted out.
    //
    // Still later: the key is to manually delete the generated app bundle,
    // rerun qmake, and rebuild (see
    // https://stackoverflow.com/questions/4739175/qt-c-on-mac-application-icon-doesnt-set).

    // removed from the dock (trashing it seems safest) so the new one can be
