Author: uwe Date: 2007-09-01 22:20:41 +0200 (Sat, 01 Sep 2007) New Revision: 2759
Added: trunk/util/superiotool/superiotool.c Removed: trunk/util/superiotool/probe_superio.c Modified: trunk/util/superiotool/Makefile Log: Rename probe_superio.c to superiotool.c. Flesh out Makefile with all the usual stuff, e.g. install targets etc.
