Recursively download directory contents with wget.
Explanation - download all files and subfolders in ddd directory:
- recursively (-r),
- not going to upper directories, like ccc/... (-np),
- not saving files to hostname folder (-nH),
- but to ddd by omitting first 3 folders aaa, bbb, ccc (--cut-dirs=3),
- excluding index.html files (-R index.html)
(obviously this depends on robots.txt not being to strict)
