The package itself used "Linux" which I modified to GNU/Linux but I'll
remove it altogether and reword it.

OK, there is so many different vendors supported so I figured I'd
include the full list, I'll try including a full list of vendors
instead.

I still have not fixed the issue where CUPS tried to find the
gutenprint-5.3 filter binary within it's own package folder instead of
gutenprint's. I'd appreciate some help for that. Otherwise will come to
investigate soon, busy with other things now but wont last too long.
