When I say steal I don't mind if people do some copy/paste (really) I just would like a word of credits if possible.
I'm no pro in the domain, but everyone can modify it (I don't know if the credits part is too much...). I wouldn't like to be seen as a guy who wants to copyright things which are so simple (and even if I wanted it, which is not the case, I wouldn't be able so)
Thanks for pointing this out, of course everyone can play with the script (which is well commented I think).
Edit : I've corrected the readme file. The "new" version is online.
