+    (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.")
