[mateen maldar <mateen maldar gmail com>]

Hi,

   i'm looking for a complete guide or a pdf manual that explains all the
    tracker framework in details .
    I'm a newbie just started with tracker but unable to understand the entire
    framework.
    Let me  know if anyone has good resource which explains the tracker
    concepts.
    Regards,
    Mateen Maldar
