    # use absolute paths for naming shared libraries, and exclude the

    # requires that you compile everything twice, which is a pain.
    # So that behaviour is only enabled if SCOABSPATH is set to a
    # non-empty value in the environment.  Most likely only useful for
    # creating official distributions of packages.
