Information system

We have a common information system (called the ``Talker'') that contains the information produced by any (automatic or commanded) action of the observing system. As more facilities use the Talker, it has become difficult to view all the information. This also includes the distinction between commands being executed from the command-line, through a user interface, or from a script. The messages provided in the Talker have been re-categorised and/or presented in a more organised way to allow an easier overview. This has been completed for the ALFOSC observing system. Improvement of the Talker information for the observing systems of the other instruments, and for the commands from the TCS will be completed in the current semester.
