Nice! I have found some broken links and strange grammar, though:

* index.html: There are archives of the main GNU Wget list at
** fly.cc.fer.hr
** www.geocrawler.com
(neither works)

* wgetdev.html
** Translation Project page
(doesn't work)

* faq.html
** 3.1 [..]
Yes, starting from version 1.10, GNU Wget support files larger than 2GB.
(should be supports)

Re: links conversion; non-existent index.html

[Ulf Harnhammar]

The following Unix command removes all files called index.html
in the current and below directories:

find . -type f -name 'index.html' -print -exec rm -f {} \;

That might be one way to solve your problem.
