"Maim" is a relatively popular, highly minimal screenshotting utility. It's mainly used by users that want to keep their system as minimal as possible. wozniak and I currently use a manually compiled version of it, as Funtoo does not have it in its kits.
I think it would benefit the Funtoo community if an ebuild for it is provided.
"Maim" is easy to autogen using GitHub YAML, and the ebuild is not complicated. I currently have an autogen ready for inclusion, as well as for its dependency "slop", which, while we do have in our kits, is not autogenned.
