clone
     
         1. An exact copy of a product, made legally or
        illegally, from {documentation} or by {reverse engineering},
        and usually cheaper.
     
        E.g. "PC clone": a PC-BUS/{ISA}, {EISA}, {VESA}, or {PCI}
        compatible {x86}-based {microcomputer} (this use is sometimes
        misspelled "klone" or "PClone").  These invariably have much more
        bang per buck than the {IB PCM} they resemble.
     
        E.g. "Unix clone": An {operating system} designed to deliver a
        {Unix}-like environment without Unix licence fees or with
        additional "mission-critical" features such as support for
        {real-time} programming.
     
        2.  A {clonebot}.
