@brief FACT++ - The FACT slow control software

@author thomas.bretz@epfl.ch et al.
@version 1.0
 
@section install_sec Installation

FACT++ can be downloaded from the svn by

\verbatim
   svn checkout https://fact.isdc.unige.ch/svn/trunk/FACT++ [localdir]
\endverbatim

it includes a dim version which is automatically compiled.

For compilation use

\verbatim
   ./configure
   make
\endverbatim

Check the \b ./configure options with \b --help. It might look 
confusing, but some features like FITS or QT4 can be switched off,
if the necessary library is not at hand and the feature is not needed.
For example, if the GUI is not needed its compilation can be switched
off by disabling QT4 support with \b --without-qt4.

In principle configure also supports

\verbatim
   make install
\endverbatim

which would install the package and the libraries in your system,
although at the moment this is not recommended

@subsection packages Required packages

hesitate to report it, so that it can be added to the list below.

@section Demo Current demonstration programs

- \b dserver2: A virtual board (A TCP/IP server). It is sending a
  "hello" message after accepting a communication and then in 3s
  intervals the current UTC time. The board can be set to state 1 or back
  to state 0 (just as a demonstration)
- \b dclient5: A control program. It accesses two viratual boards (start them
  with 'dserver2 5000' and 'dserver2 4001') If both boards are connected the START
  command can be issued to get them to state 'Running'. In this state
  an asynchronous time stamp can be requested sending the TIME command.
  to get back from Running to Connected use STOP. 
- \b test3: a dim console which allows to control all dim servers
  by sending commands via the dim network.
- Both, \b dclient5 and \b test3 accept the command line options -c0, -c1, -c2
  to switch between different console types (or no console in the case of
  \b dclient5). In the console you get help with 'h' and the available
  command with 'c' You get the avilable command-line options with --help

First start the two dserver2s. Then start a dclient5 (if you want it
with console use one of the -c options) and a test3 console (with one
of the console options if you like) you can now control the hardware
boards with the START, STOP and TIME commands or stop (Ctrl-C) and
start one of the programs to see what's happening. In the test3 case
you first have to \e cd to the server to which you want to talk by \b
DATA_LOGGER. Don't forget to start \b dns if you want to control dclient5
from test3 via Dim.

@section exitcodes Exit Code
@section newcommand How to add a new command?
@section description How to add help textes to services and commands?

@section addtab How to add a new tab in the gui?

Do the following steps in exactly this order:
- Insert the new page from the context menu of the QTabWidget
- Copy the QDockWidget from one of the other tabs to the clipboard
- Paste the copied QDockWidget and add it to the new tab (only the tab should be highlited)
- Now click on the context menu of the region in the tab (QWidget) and change the layout to grid layout


@section Documentation

Each program has an extensive help text (except the examples). This help text can
be displayed with the \b --help option. For each program a man-page is automatically
created (from the help-output), which (at the moment) can be accessed with <B>man
FILE</B>.
