In what order does httrack crawl a site? Does it do it 
width first, or depth first? e.g. does it follow the first 
link on the home page to the second level, then follow the 
first link it finds there to the third level, and so on 
until it reaches the boundary of the site, then move up a 
level and follow the next link there (depth first). Or is 
the behavior to follow each of the links in the home page 
to the second level (width first).

Many thanks
