+//! This class provide handy parsing of command-line arguments. First you should add
+//! arguments to %PICLI with function \a addArgument(). Then you can check if there
+//! is some argument in application command-line with function \a hasArgument(),
+//! or obtain argument value by \a argumentValue().
+//!
+//! \~russian
+//! Этот класс предоставляет удобный механизм для разбора аргументов командной строки.
+//! Сперва необходимо добавить аргументы в %PICLI с помощью методов \a addArgument().
+//! Далее можно проверять аргументы на наличие в командной строке методом \a hasArgument(),
+//! а также получать их значения при помощи \a argumentValue().
+//!
+//! \~english \section PICLI_sec1 Example
+//! \~russian \section PICLI_sec1 Пример
+//! \~\code
+//! int main(int argc, char ** argv) {
+//! 	PICLI cli(argc, argv);
+//! 	cli.addArgument("console");
+//! 	cli.addArgument("debug");
+//! 	cli.addArgument("Value", "v", "value", true);
+//! 	if (cli.hasArgument("console"))
+//! 		piCout << "console active";
+//! 	if (cli.hasArgument("debug"))
+//! 		piCout << "debug active";
+//! 	piCout << "Value =" << cli.argumentValue("Value");
+//! 	return 0;
