 * info_netbsd.cpp is part of the KDE program kcminfo.  This displays
 * various information about the OpenBSD system it's running on.
 *
 * Originally written by Jaromir Dolecek <dolecek@ics.muni.cz>. CPU info
 * code has been imported from implementation of processor.cpp for KDE 1.0
 * by David Brownlee <abs@NetBSD.org> as found in NetBSD packages collection.
 * Hubert Feyer <hubertf@NetBSD.org> enhanced the sound information printing
 * quite a lot, too.

 * The code is placed into public domain. Do whatever you want with it.
