Segment named ORIGINAL contains the original code, disassembled or provided in
a binary form. Subsequent four segments will be relocated to addresses
specified by their "start" attributes ("offset" can also be used) and then will
overwrite whatever was at these locations in the ORIGINAL segment. In the end,
resulting binary output file will thus contain original data with the exception
of four sequences starting at $9000, $f7e8, $8000 and $e5b7, which will sport
code from their respective segments. How long these sequences will be depends
on the lengths of corresponding segments - they can even overlap, so think what
you're doing.

Finally, note that OVERWRITE segments should be the final segments loaded to a
particular memory area, and that they need at least one of "start" or "offset"
