I already posted the command line from doit.log; here is the one from
hts-log.txt:

(winhttrack -qw%e1C2%Pns0%s%uN0%I0p3DaK0H0%kf2A25000%f#f -F "Mozilla/4.5
(compatible; HTTrack 3.0x; Windows 98)" -%F "<!-- Mirrored from %s%s by
HTTrack Website Copier/3.x [XR&CO'2010], %s -->" -%l "nl, en, *"
<http://auto.howstuffworks.com/stirling-engine.htm> -O1 E:\I\Escape
-auto.howstuffworks.com/* +auto.howstuffworks.com/stirling-engine* )

Thanks for looking into this!
