Awesome wrapper tool to set background
awsetbg [-fctaFCTA wallpaper] [-uU wallpapersetter] [-m #] [-bB fbsetrootoptions ...] [-rR path] [-l]
awsetbg is a wrapper that tries to find a suitable background setting application and then tries to set the wallpaper using that application. You do not have to configure awsetbg, since it just uses the first application it finds.
Furthermore, it remembers the last wallpaper set, so you do not have to edit anything to change the wallpaper.
