... soooooo ...
Shouldn't we make UPP one of first things in the world supporting it? I think it can earn some nice share of PR.
I'm willing to look a bit into it, but need somebody who will keep nagging me and help with tedious stuff. Like reading the link I posted, because I don't have time right now, and write here what's the state of the format and if it's ready to be implemented.
And if there's some MIT/BSD compatible license lib, so it's just about upp plugin wrapper, or we have to recreate it from definition.
If anyone else is interested in this, write it here, so we know about each other and can coordinate our effort.
