URI

            GUI\URI

        Open any kind of URI (Uniform Resource Identifier), e.g.  html  link  or
        file names, for example:
          GUI\URI  "http://www.iram.fr/IRAMFR/GILDAS/"  "GILDAS Web Page"
          GUI\URI  gag_doc:pdf/gildas-intro.pdf         "GILDAS Introduction"

        The choice of the software used to open the URI is let as much as possi-
        ble to the system (which should itself honor the user's preferences).
