"""RushNotesMerge.py

            EXPERIMENTAL - USE WITH CARE

Merge .queue file with hero's note to generate fresh .merge file

normal usage 
$> ./pyfpdb/RushNotesMerge.py "/home/foo/.wine/drive_c/Program Files/Full Tilt Poker/heroname.xml"

The generated file can then replace heroname.xml (if all is well).
