+generated in the kernel directly to userspace through character devices that
+are typically located in @file{/dev/input/}.
+
+This package also comes with bindings to @code{uinput}, the userspace input
+subsystem.  @code{uinput} allows userspace programs to create and handle input
+devices that can inject events directly into the input subsystem.")
