Re: ACPI+Userspace

[Jeremy Moles <jeremy-9vekgGPT+OA7YuNMryXyOw@public.gmane.org>]

Well, spent some time Friday night and went ahead and did it. README
included, along with some stuff in the source which may/may not be
correct. :/ In particular, the sscanf may be hackish... I do mostly C++
and python code, so I'm not that good C string stuff. All comments are
welcome.

P.S. The Makefile has "make in" and "make out" targets. Any OS that lets
you type "make out" at a commandline--and then do something
interesting--is just fine by me. :)
