Alad [1] filed a deletion request for yaourt [2]: This was already deleted twice and apparently resubmitted "by accident". PS. If you want to maintain pacdiffviewer [1], please submit it as a seperate project/package to make this fact clear. Looking over the makefile, it should suffice to include io.sh/util.sh/pacman.sh.
