>     The <B
CLASS="GUIMENU"
>GNOME System Monitor</B
> menu entry starts a 
     program called <TT
CLASS="APPLICATION"
>gtop</TT
>. 
     <TT
CLASS="APPLICATION"
>gtop</TT
> is a graphical version of a text 
     program called <TT
CLASS="APPLICATION"
>top</TT
>. It displays information 
     about all the programs running on your computer. There are three ways 
     to start it:
    <P
></P
><UL
><LI
><P
>        At the command line, type <B
CLASS="COMMAND"
>gtop</B
>.
      </P

>       If you have the <TT
CLASS="APPLICATION"
>multi_load applet</TT
> running
       on your GNOME panel, then you can start gtop by right-clicking on
       the applet and selecting the <B
CLASS="COMMAND"
>Run gtop</B
> option.

>     UNIX and UNIX-like systems (Linux, Solaris, *BSD and so on) are 
     multi-tasking, which means that they can run more than one program
     at a time. Each program can run one or more "tasks", or processes.
     All these processes share processor (CPU) time and memory. Whilst
     only one process can talk to a CPU at a time, the processes take 
     turns at this which are very short. The result is that all the
     programs on the machine can proceed. gtop produces one or more 
     constantly-updated windows which show you snapshots of the state of 
     your system. The display can show you:

    <P
></P
><OL
TYPE="1"
><LI
><P
>        processes: which processes are currently the most active and what 
        they are doing;
      </P
></LI
><LI
><P
>        memory: how much memory is available and how much is in use;
      </P
></LI
><LI
><P
>        filesystems: how much of the filesystem is full or empty.
      </P
></LI
></OL
>
   </P
><P
>     The gtop window also shows some additional system information 
     at the bottom. In all windows, a menubar and toolbar are visible. 
     These let you customise the current display of information or 
     switch to a different display. In addition, you can get more 
     information on a particular process by clicking on the name of 
     that process in the process window.
   </P
><P
>      By default, gtop will begin with the first window: processes.
