Okay, thanks for the tip Ben. I already updated the module to use this 
scheme.

Maybe we could push our repo to fd.o. What do you think guys? But I 
don't know exactly how the copyright and license stuffs will work 
though. All the fd.o repositories must be in MIT?

(btw, me and Paulo take the initiative to take the code and add our 
copyright there, so please Benjamin tell if something sounds strange to 
you there)
