lamelos [1] filed a deletion request for gulden-bin [2]: Gulden.com now provides an AppImage instead of a standalone binary image. I've created a new package for the AppImage, see: https://aur.archlinux.org/packages/gulden-appimage/.
That package supersedes this one, so this one can be deleted. [1] https://aur.archlinux.org/account/lamelos/ [2] https://aur.archlinux.org/pkgbase/gulden-bin/
