or take an argument (e.g. \c{-o file}).

\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.
