    /// `GApplicationCommandLine` represents a command-line invocation of
    /// an application.
    ///
    /// It is created by [`Application`][crate::Application] and emitted
    /// in the [`command-line`][struct@crate::Application#command-line] signal and virtual function.
    ///
    /// The class contains the list of arguments that the program was invoked
    /// with. It is also possible to query if the commandline invocation was
    /// local (ie: the current process is running in direct response to the
    /// invocation) or remote (ie: some other process forwarded the
    /// commandline to this process).
    ///
    /// The `GApplicationCommandLine` object can provide the @argc and @argv
    /// parameters for use with the `GLib::OptionContext` command-line parsing API,
    /// with the [`ApplicationCommandLineExt::arguments()`][crate::prelude::ApplicationCommandLineExt::arguments()] function. See
    /// [gapplication-example-cmdline3.c][gapplication-example-cmdline3]
    /// for an example.
    ///
    /// The exit status of the originally-invoked process may be set and
    /// messages can be printed to stdout or stderr of that process.
    ///
    /// For remote invocation, the originally-invoked process exits when
    /// [`ApplicationCommandLineExt::done()`][crate::prelude::ApplicationCommandLineExt::done()] method is called. This method is
    /// also automatically called when the object is disposed.
    ///
    /// The main use for `GApplicationCommandLine` (and the
    /// [`command-line`][struct@crate::Application#command-line] signal) is 'Emacs server' like use cases:
    /// You can set the `EDITOR` environment variable to have e.g. git use
    /// your favourite editor to edit commit messages, and if you already
    /// have an instance of the editor running, the editing will happen
    /// in the running instance, instead of opening a new one. An important
    /// aspect of this use case is that the process that gets started by git
    /// does not return until the editing is done.
    ///
    /// Normally, the commandline is completely handled in the
    /// [`command-line`][struct@crate::Application#command-line] handler. The launching instance exits
    /// once the signal handler in the primary instance has returned, and
    /// the return value of the signal handler becomes the exit status
    /// of the launching instance.
