These links are old and in need of udating. I will get around to doing it but it will take some time. They remain as a source of information and a good place to start a web search in this area. BUT beofre you start here, check out the Projects page which is more up to date. After a number of comments about the length and download time of the original Links page, I have split it into a number of smaller pages. This should make faster loading and gereally happier viewing.
