-> By default, when the lttv GUI starts with all the graphical modules loaded,
-it loads the statistics viewer, the control flow viewer, and the detailed event
-list inside a tab. Other viewers can be added later to this tab by interacting
-with the main window. Let's describe the operations available on the window :

-> This toolbar allows you to navigate through the basic functionnalities of LTTV.
-The first button opens a new window and the second one, a new tab. You can leave
-your mouse over the buttons to read the information provided by the tooltips.
-</P
-></LI
-><LI
-><P
-> This notebook, containing different tabs, lets you select the "Trace Set" you
-want to interact with. A trace set is an aggregation of traces, synchronised in
-time. You may also want to use one tab per viewer by simply cloning the traceset
-to a new tab. This way, you can have vertically stacked viewers in one tab, as
-well as different viewers, independant from the time interval. Note that once
-the Trace Set cloning is done, each trace set becomes completely independant.
-For Traceset cloning, see the File Menu.
-</P
-></LI
-><LI
-><P
-> These buttons let you control the computation in progress on a trace. As
-sometimes the computation may last for a while, you may want to stop it, restart
-it from the beginning or simply to continue from where you stopped. This is
-exactly what those three buttons offer you.
-</P
-></LI
-><LI
-><P
-> Buttons on the right side of the last spacer are semantically different from the
-others. While the other buttons at the left side of the bar are built in the
-lttv program and let you operate the basic functionnalities, the buttons at the
-right side let you add a viewer to the active Tab. They belong to the
-viewers themselves. The number of buttons that appears there should directly
-depend on the number of viewer's modules loaded.
-</P

-><LI
-><P
-> This is a tree representing the multiple statistics available for the current
-traceset. This is shown by the guistatistics viewer.
-</P
-></LI
-><LI
-><P
-> This is the Y axis of the guicontrolflow viewer. It shows the process list of
-the traced system. You may notice that it grows : it dynamically adds
-process when they appear in the trace.

-><P
-> This is a (missing) time bar for the X axis. Maybe will it be used for viewer
-specific buttons eventually. Work in progress.

-> The is the current time selected. The concept of current event and current time
-selected is synchronised in a Tab for all the viewers. The control flow viewer
-shows it a vertical white dotted line. You move this marker by clicking on the
-background of the process state graph. This graph shows evolution of each
-process's state through time. The meaning of the colors will be explained later.
-</P
-></LI
-><LI
-><P
-> This is the details event list. It shown the detailed information about each
-event of the trace. It is synchronised with the current time and current event,
-so selecting an event changes other viewer's current time and reciprocally.
-</P
-></LI
-><LI
-><P
-> You can enter the values of start time and end time you wish to see on the
-screen here. It also supports pasting time as text input, simply by clicking of
-the "Time Frame", "start" or "end:" fields. A valid entry consists of any
-digital input separated by any quantity of non digital characters. For example :
-"I start at 356247.124626 and stop at 724524.453455" would be a valid input
-for the "Time Frame" field.
-</P
-></LI
-><LI
-><P
-> This horizontal scrollbar modifies the window of time shown by all the viewers
-in the tab. It is linked with the fields below it (described at number 10 and
-12). Another way to modify the time shown is to use the zoom buttons of the
-toolbar (yes, the ones that looks like magnifying glasses).
-</P
-></LI
-><LI
-><P
-> This field works just like the "Time Frame" field. It modifies the current time
-selected by the viewers. For example, changing its value will change the current
-event selected by the detailed events list and the current time selected by the
-control flow viewer.
