In order to be able to run QTads on your system, you will need to have the
following libraries installed.  You can install them using your Linux
distribution's package manager:

  * Qt 4 GUI library
  * SDL library

If you're using Ubuntu 11.10 or newer, or have KDE installed, you have Qt
already installed.  If not, the package is usually called something like
"libqt4" or "libqt4-gui".  Likewise, the SDL package is most likely called
"libsdl", "libsdl1.2" or "libsdl1.2debian".

If you have a system where you compiled SDL yourself, make sure that it
was built with audio and timers support.  (Anything else, like video, is
not needed.)
