And there comes the idea I was talking about. I think that scripts should
behave according to the operating from where they are running on. I'm doing
some changes to scripts for doing so, but it will take me few days to have
something useable.
I also think that every portable code should be welcome whenever it doesn't
break anything in ArchLinux and made scripts runnable on other OSes.

What do you guys think?
