These are experiments, and watch the time-stamps of the packages.

Note that these are (and will remain for the time being) development packages. They
create a directory /opt/nemo_4.2 (and a symlink from /opt/nemo_4.2 -> /opt/nemo) but
contain the full .git history, so you can simply do things like

        source /opt/nemo/nemo_start.sh
        mknemo -u tsf

assuming you have a generic version. With some luck this may give you arbitrary upgrades.
The testsuite can be run as follows

        $NEMO/src/scripts/testsuite
