Subject: Regex to find urls in text?

On our site, our resources have a description, which is often copied and
pasted from somewhere else.  Often these descriptions have urls in them,
just as normal text, and i'd like to automatically make these into
working links.

I was thinking of using gsub as below:

def description_with_links
  regex = ????
  self.description.gsub(regex) {|url|"<a href=\'#{url}'>#{url}</a>"}
end

The above should work ok, once i have the regex but i can't work it out.
Can anyone help?

thanks
max
