/*
 testqtargs -- is there really a bug in TDECmdLineArgs or am I on crack?

  I used the following compile options:

  g++ -g -Wall -o testqtargs testqtargs.cpp  -I/usr/X11R6/include \
  -I/opt/qt3/include -I/opt/trinity/include -L/usr/X11R6/lib -L/opt/qt3/lib \
  -L/opt/trinity/lib -lqt -ltdecore

  if invoked like this ./testqtargs --bg blue --caption something --hello hi

  The program should list argv[] then produce output like this:
  
  qt arg[0] = background
  qt arg[1] = blue
  arg bg = blue
  arg caption = something
  arg hello = hi

  Instead for me it prints:

  qt arg[0] = -background
  qt arg[1] = blue
  arg caption = something
  arg hello = hi

  See the extra dash in qt arg[0]?  I believe that is the cause of the problem.
  --bg is aliased to --background but If you try it with --background or 
  -background, you get the same thing.

  in tdecore/tdeapplication.cpp, TDECmdLineOption qt_options is defined and used 
  by the static method Kapplication::addCmdLineOptions to add the Qt options
  but its' entries look like this:

  { "background <color>", I18N_NOOP("sets the default background color and an\n
application palette (light and dark shades are\ncalculated)."), 0},

  it looks for "background"  instead of "-background" so never find the arg.

  Software:  g++ 2.95, tdelibs from CVS Jan 28, Qt 3.01
  OS: Debian GNU/Linux 3.0 (sid)
