Hi,
I've started using httrack with command line from another application. 
The user's guide by Fred Cohen is pretty clear in explaining the wide variety
of options. But for me there's one question left: 
How can i check, wether a download has been completed? Check the existence of
hts-in_progress.lock or do i have to read hts-log.txt and look after the
string 'mirror complete'? Or is there meanwhile another way to prove this?
