 /* dmesg.c -- Print out the contents of the kernel ring buffer
  * Created: Sat Oct  9 16:19:47 1993
  * Revised: Thu Oct 28 21:52:17 1993 by faith@cs.unc.edu
  * Copyright 1993 Theodore Ts'o (tytso@athena.mit.edu)
  * This program comes with ABSOLUTELY NO WARRANTY.
  * Modifications by Rick Sladkey (jrs@world.std.com)
- * from util-linux; adapted for busybox
+ * Larger buffersize 3 June 1998 by Nicolai Langfeldt, based on a patch
+ * by Peeter Joot.  This was also suggested by John Hudson.
+ * 1999-02-22 Arkadiusz Mi¶kiewicz <misiek@misiek.eu.org>
+ * - added Native Language Support
+ *
+ * from util-linux -- adapted for busybox by 
+ * Erik Andersen <andersee@debian.org>. I ripped out Native Language 
+ * Support, replaced getopt, added some gotos for redundant stuff.
