Gnus /ɡᵊˈnuːz/, or Gnus Network User Services, is a message reader which is part of GNU Emacs. (It also works in XEmacs.) It supports reading and composing both e-mail and news and can also act as an RSS reader, web processor, and directory browser for both local and remote filesystems.Gnus blurs the distinction between news and e-mail, treating them both as "articles" that come from different sources.
