[aur-general] outdated package: "jpegtran" flagged as outdated since 2011-08-02

Hello, the package "jpegtran" is flagged outdated since 2011-08-02 and I want to use it. https://aur.archlinux.org/packages.php?ID=20176 Can the maintainer be triggered to update, or can the package maintainer be changed? if the maintainer don't want to update it, I could adopt it. Ciao, Oliver
