This package contains a copy of FOF 2.x with its class prefixes renamed from FOF to F0F
    (F-zero-F). Moreover, the installation path changed from
    JPATH_LIBRARIES . '/fof' to JPATH_LIBRARIES . '/f0f' (again: that's f-zero-f). The same
    goes for the FOF_INCLUDED constant which is now called F0F_INCLUDED (again: that's
    f-zero-f). If you want to use this version please remember to change these instances from FOF to
    F0F.
