# rofi-bang
#
# Allows execution of arbitrary commands through rofi by
# invoking shell scripts. These shell scripts can in turn
# of course be other rofi commands, which allows the creation
# of chained rofi executions (e.g. !c 1+2) to run a
# calculator script within rofi and immediately execute it.
# Hence, rofi-bang.
