Xrn has a graphical windows interface and
only runs on the RCS workstations.
Xrn uses a window that is divided into a top
half and a bottom half. The top half usually contains the list of
articles in a group and buttons to indicate what you can do with the articles.
The
bottom half usually contains the article that you are reading and more
buttons allowing you to react to the article. (There
are exceptions to both these cases.) See memo RPI.112, Using UNIX
Workstations, for
further details about using the RCS workstations.
