Re : duplicate parts

[jean legrand <kkwweett yahoo fr>]

with some effort (missing docs), I have written this solution. Sorry in advance for the identation. 
I've left the loop range idea away and the script only copies the content of a part into another, both parts given in arguments.
I'm not very happy with the constant 2147483647 but I don't know how to say "find for all times".
Also, I think there is a more elegant way to find a part from its name but I can't find out which one.

Can you help me improve this code ?
