- New: "debian" directory holding the paraphernalia needed to create a
        Debian/Ubuntu package.
    - New: In buildCoriolis, add a Debian packaging method.
    - Change: In coriolis2.spec, the build/install procedure now makes uses of
        the top-level Makefile.
    - Change: In FindBoostrap, detection of the distribution type. Finally not
        needed but kept here, just in case. Based on "lsb_release".
    - Change: In FindPythonSitePackages, simplificate the detection of the Python
        site-package directory. No longer on-the-fly generate a python script.
