/** ApplicationCommandLine - A command-line invocation of an application.
 * ApplicationCommandLine represents a command-line invocation of an
 * application. It is created by Application and emitted in the "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 ApplicationCommandLine object can provide the argc and argv parameters
 * for use with the Glib::OptionContext command-line parsing API, with the
 * get_arguments() method.
 *
 * The exit status of the originally-invoked process may be set and messages
 * can be printed to stdout or stderr of that process. The lifecycle of the
 * originally-invoked process is tied to the lifecycle of this object (ie: the
 * process exits when the last reference is dropped).
 *
 * The main use for ApplicationCommandline (and the "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.
