-    (description "@code{Barrier} is software that mimics the functionality of
-a KVM switch, which historically would allow you to use a single keyboard and
-mouse to control multiple computers by physically turning a dial on the box to
-switch the machine you're controlling at any given moment.  Barrier does this
-in software, allowing you to tell it which machine to control by moving your
-mouse to the edge of the screen, or by using a keypress to switch focus to a
-different system.")
