    Can anyone suggest a good tutorial for reading
    and writing binary files in Perl or send me some tips or examples?
    I tried using pack and unpack and seek and read
    but things don't work as expected so I must be missing
    some subtle details.

    For example: I tried reading a .RAW image file (no header info) and
    writing it back out
    using seek read and print.
    It almost worked but any part of the image that was black
    threw things off. I suspect maybe the zeros (black) were somehow
    being interpreted as EOF or NUL or something.
    I also suspect that there are issues with word boundries I don't quite
    grasp.

    Thanks,
    -Steve
