beamer is a simple command line tool for toggling and positioning a secondary monitor or projector on Linux.
It is a thin wrapper for xrandr to spare you typing out common setups in its verbose syntax. Consequently, it requires xrandr to be installed on your system.

Commands

Commands assume the first output listed by xrandr to be the main output (e.g. a laptops monitor).
