cl-evdev is meant to be a drop-dead simple driver for teasing out events from Linux’s /dev/input drivers. It was originally designed for the Navi project, as part of the silica keyboard handling routines.

Note: this code is by no means complete, and is less than alpha quality code. I’ve tested it on SBCL and Ubuntu Linux 3.x as well as the embedded Linux kernel built for Intel Edison boards, but nothing else.

Use your typical ASDF system definition package, be it the old, deprecated ASDF, or quicklisp.
