The eprintf removed and replaced with err & warn. Option parsing no longer tries to find missing optargs, which are getopts should notice. Few complier warnings got to be removed as well. Finally the commments will no longer exceed standard terminal width. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
