gnu-netcat and openbsd-netcat perform same function,only 1 can be or needs to be installed, both included because of conflicts.There are used to check that network is "up" at various points in program.
Auracle and trizen are both AUR helpers you can installone or both depending on preference. Auracle is a more minimalist helper.trizen is more fully featured.Auracle is used for -u and -n functions, plus step 24 of the package list makerAuracle is new and still in development hence the -git extension.libnotify should be installed on the vast majority of Arch systems already.dialog should already be installed in an arch linux system installed bythe arch linux installation guide on wiki. If you install Arch some other wayIt may not be there, so included as depends.expac is used a lot and will be already installed on many systems.pacman_contrib contains numerous tools(checkupdates pacache etc)related to pacman.
