I want to get user's default screenshooter application. Like, in a fresh install Ubuntu, it is gnome-screenshot, or in Xubuntu it is xfce4-screenshooter. Or maybe Distro A's screenshooter is imagemagick's import, I don't know.
How can I check this?
I'm trying to test whether the user has a screenshooter, a screen capture utility. If so, I'll use it and capture screen, for example.
How can I accomplish this?
