    The major problem we have here is that requirements are contained in

    What we do here, simply, is to chain the various requirements files (the
    ``requirements_files`` attribute, a list of paths to requirements files
    expressed as tuples of components) together, keeping a single entry for
    each package with the ones coming later overriding the first ones.

    The ``extras`` is a list of extra requirement to add and the ``remove``
    option is a list of keys (lowercase names of projects) not to install
    (despite being in some requirement files)
