-    It is also used to describe how the option is used - it may be a flag (e.g. \c{-v})
-    or take an argument (e.g. \c{-o file}).

-/*!
-    \since 5.2
-    \class QCommandLineParser
-    \inmodule QtCore
-    \ingroup tools
-
-    \brief The QCommandLineParser class provides a means for handling the
-    command line options.
-
-    QCoreApplication provides the command-line arguments as a simple list of strings.
-    QCommandLineParser provides the ability to define a set of options, parse the
-    command-line arguments, and store which options have actually been used, as
-    well as option values.
-
-    Any argument that isn't an option (i.e. doesn't start with a \c{-}) is stored
-    as a "positional argument".
-
-    The parser handles short names, long names, more than one name for the same
-    option, and option values.
-
-    Options on the command line are recognized as starting with a single or
-    double \c{-} character(s).
-    The option \c{-} (single dash alone) is a special case, often meaning standard
-    input, and not treated as an option. The parser will treat everything after the
-    option \c{--} (double dash) as positional arguments.
-
-    Short options are single letters. The option \c{v} would be specified by
-    passing \c{-v} on the command line. In the default parsing mode, short options
-    can be written in a compact form, for instance \c{-abc} is equivalent to \c{-a -b -c}.
-    The parsing mode for can be set to ParseAsLongOptions, in which case \c{-abc}
-    will be parsed as the long option \c{abc}.
-
-    Long options are more than one letter long and cannot be compacted together.
-    The long option \c{verbose} would be passed as \c{--verbose} or \c{-verbose}.
-
-    Passing values to options can be done using the assignment operator: \c{-v=value}
-    \c{--verbose=value}, or a space: \c{-v value} \c{--verbose value}, i.e. the next
-    argument is used as value (even if it starts with a \c{-}).
-
-    The parser does not support optional values - if an option is set to
-    require a value, one must be present. If such an option is placed last
-    and has no value, the option will be treated as if it had not been
-    specified.
-
-    The parser does not automatically support negating or disabling long options
-    by using the format \c{--disable-option} or \c{--no-option}. However, it is
-    possible to handle this case explicitly by making an option with \c{no-option}
-    as one of its names, and handling the option explicitly.
-
-    Example:
-    \snippet code/src_corelib_tools_qcommandlineparser_main.cpp 0
-
-    Known limitation: the parsing of Qt options inside QCoreApplication and subclasses
-    happens before QCommandLineParser exists, so it can't take it into account. This
-    means any option value that looks like a builtin Qt option, will be treated by
-    QCoreApplication as a builtin Qt option. Example: \c{--profile -reverse} will
-    lead to QGuiApplication seeing the -reverse option set, and removing it from
-    QCoreApplication::arguments() before QCommandLineParser defines the \c{profile}
-    option and parses the command line.

-    \enum QCommandLineParser::SingleDashWordOptionMode
-
-    This enum describes the way the parser interprets command-line
-    options that use a single dash followed by multiple letters, as as \c{-abc}.
-
-    \value ParseAsCompactedShortOptions \c{-abc} is interpreted as \c{-a -b -c},
-    i.e. as three short options that have been compacted on the command-line,
-    if none of the options take a value. If \c{a} takes a value, then it
-    is interpreted as \c{-a bc}, i.e. the short option \c{a} followed by the value \c{bc}.
-    This is typically used in tools that behave like compilers, in order
-    to handle options such as \c{-DDEFINE=VALUE} or \c{-I/include/path}.
-    This is the default parsing mode. New applications are recommended to
-    use this mode.
-
-    \value ParseAsLongOptions \c{-abc} is interpreted as \c{--abc},
-    i.e. as the long option named \c{abc}. This is how Qt's own tools
-    (uic, rcc...) have always been parsing arguments. This mode should be
-    used for preserving compatibility in applications that were parsing
-    arguments in such a way.
