+/**
+ *  @short A class for command-line argument handling.
+ *
+ *  KCmdLineArgs provides simple access to the command-line arguments
+ *  for an application. It takes into account Qt-specific options,
+ *  KDE-specific options and application specific options.
+ *
+ *  This class is used in %main() via the static method
+ *  init().
+ *
+ *  A typical %KDE application using %KCmdLineArgs should look like this:
+ *
+ *  \code
+ *  int main(int argc, char *argv[])
+ *  {
+ *     // Initialize command line args
+ *     KCmdLineArgs::init(argc, argv, appName, programName, description, version);
+ *
+ *     // Tell which options are supported
+ *     KCmdLineArgs::addCmdLineOptions( options );
+ *
+ *     // Add options from other components
+ *     KUniqueApplication::addCmdLineOptions();
+ *
+ *     ....
+ *
+ *     // Create application object without passing 'argc' and 'argv' again.
+ *     KUniqueApplication app;
+ *
+ *     ....
+ *
+ *     // Handle our own options/arguments
+ *     // A KApplication will usually do this in main but this is not
+ *     // necessary.
+ *     // A KUniqueApplication might want to handle it in newInstance().
+ *
+ *     KCmdLineArgs *args = KCmdLineArgs::parsedArgs();
+ *
+ *     // A binary option (on / off)
+ *     if (args->isSet("some-option"))
+ *        ....
+ *
+ *     // An option which takes an additional argument
+ *     QCString anotherOptionArg = args->getOption("another-option");
+ *
+ *     // Arguments (e.g. files to open)
+ *     for(int i = 0; i < args->count(); i++) // Counting start at 0!
+ *     {
+ *        // don't forget to convert to Unicode!
+ *        openFile( QFile::decodeName( args->arg(i)));
+ *        // Or more convenient:
+ *        // openURL( args->url(i));
+ *
+ *     }
+ *
+ *     args->clear(); // Free up some memory.
+ *     ....
+ *  }
+ *  \endcode
+ *
+ *  The options that an application supports are configured using the
+ *  KCmdLineOptions class. An example is shown below:
+ *
+ *  \code
+ *  static const KCmdLineOptions options[] =
+ *  {
+ *     { "a", I18N_NOOP("A short binary option"), 0 },
+ *     { "b \<file>", I18N_NOOP("A short option which takes an argument"), 0 },
+ *     { "c \<speed>", I18N_NOOP("As above but with a default value"), "9600" },
+ *     { "option1", I18N_NOOP("A long binary option, off by default"), 0 },
+ *     { "nooption2", I18N_NOOP("A long binary option, on by default"), 0 },
+ *     { ":", I18N_NOOP("Extra options:"), 0 },
+ *     { "option3 \<file>", I18N_NOOP("A long option which takes an argument"), 0 },
+ *     { "option4 \<speed>", I18N_NOOP("A long option which takes an argument, defaulting to 9600"), "9600" },
+ *     { "d", 0, 0 },
+ *     { "option5", I18N_NOOP("A long option which has a short option as alias"), 0 },
+ *     { "e", 0, 0 },
+ *     { "nooption6", I18N_NOOP("Another long option with an alias"), 0 },
+ *     { "f", 0, 0 },
+ *     { "option7 \<speed>", I18N_NOOP("'--option7 speed' is the same as '-f speed'"), 0 },
+ *     { "!option8 \<cmd>", I18N_NOOP("All options following this one will be treated as arguments"), 0 },
+ *     { "+file", I18N_NOOP("A required argument 'file'"), 0 },
+ *     { "+[arg1]", I18N_NOOP("An optional argument 'arg1'"), 0 },
+ *     { "!+command", I18N_NOOP("A required argument 'command', that can contain multiple words, even starting with '-'"), 0 },
+ *     { "", I18N_NOOP("Additional help text not associated with any particular option") 0 },
+ *     KCmdLineLastOption // End of options.
+ *  };
+ *  \endcode
+ *
+ *  The I18N_NOOP macro is used to indicate that these strings should be
+ *  marked for translation. The actual translation is done by KCmdLineArgs.
+ *  You can't use i18n() here because we are setting up a static data
+ *  structure and can't do translations at compile time.
+ *
+ *  Note that a program should define the options before any arguments.
+ *
+ *  When a long option has a short option as an alias, a program should
+ *  only test for the long option.
+ *
+ *  With the above options a command line could look like:
+ *  \code
+ *     myapp -a -c 4800 --display localhost:0.0 --nooption5 -d /tmp/file
+ *  \endcode
+ *
+ *  Long binary options can be in the form 'option' and 'nooption'.
+ *  A command line may contain the same binary option multiple times,
+ *  the last option determines the outcome:
+ *  \code
+ *     myapp --nooption4 --option4 --nooption4
+ *  \endcode
+ *  is the same as:
+ *  \code
+ *     myapp --nooption4
+ *  \endcode
+ *
+ *  If an option value is provided multiple times, normally only the last
+ *  value is used:
+ *  \code
+ *     myapp -c 1200 -c 2400 -c 4800
+ *  \endcode
+ *  is usually the same as:
+ *  \code
+ *     myapp -c 4800
+ *  \endcode
+ *
+ *  However, an application can choose to use all values specified as well.
+ *  As an example of this, consider that you may wish to specify a
+ *  number of directories to use:
+ *  \code
+ *     myapp -I /usr/include -I /opt/kde/include -I /usr/X11/include
+ *  \endcode
+ *  When an application does this it should mention this in the description
+ *  of the option. To access these options, use getOptionList()
+ *
+ *  Tips for end-users:
+ *
+ *  @li Single char options like "-a -b -c" may be combined into "-abc"
+ *  @li The option "--foo bar" may also be written "--foo=bar"
+ *  @li The option "-P lp1" may also be written "-P=lp1" or "-Plp1"
+ *  @li The option "--foo bar" may also be written "-foo bar"
