% This is an almost-replacement for the standard {url} pakage.
% However, it should be used as a function "\url{www.foo/bar}" rather
% than as font-changer "{\url www.foo/bar}". To maintain compatibility
% with both packages, this and the standard one, we suggest that both styles
% be used at the same time, namely "{\url{www.foo/bar}}".
