This takes a list of urls as an argument and generates a unnumbered html list consisting of those urls inside links to those urls. It is for use for refering to pages on which urls occur.
Obviously, if the URLs are file urls, then the machine they are being read on must be the same as the one the file urls refer to.
This method puts out a url inside a link refering to that url. I don't want to encourage this for general use: it's much better to use a description generally. This program, however, deals directly with links so it suits us here.
