fbsetbg(1) is a wrapper that tries to find a suitable background-setting app and then
tries to set the wallpaper using that app. You don’t have to configure fbsetbg. It just
uses the first app it can find.
Furthermore it supports remembering the last set wallpaper so you don’t have to edit the
style or init-file to change the wallpaper.
It aims to provide clear error messages in a window that make debugging problems easy.
