+I very much doubt that you can use the code "as is" for a real system, but feel
+free to take it as a starting point if that seems helpful. Since it's under a
+0-clause BSD license, which essentially makes it public domain, you're welcome
+to do as you please. If the code was helpful to you I'd *appreciate* an email,
+but it's certainly not required.
