I want the same type of thing, I think:  to download all .PDF files offered
(for free) by a certain website.  I don't need anything else.  So I have used
as a scan rule:

-* +www.example.net/*.html +*.pdf

I also used "not follow robots.txt rules" because I think that was an initial
problem.

However, I still get only the site's home page and the single PDF offered on
it, with no other content.

Any ideas will be appreciated.

Thanks for a great program.
