-		Header-Only C++ Mathematical Optimization Library for 'Armadillo'
-		// 'Ensmallen' is a templated C++ mathematical optimization
-		library (by the 'MLPACK' team) that provides a simple set of
-		abstractions for writing an objective function to optimize.
-		Provided within are various standard and cutting-edge
-		optimizers that include full-batch gradient descent techniques,
-		small-batch techniques, gradient-free optimizers, and
-		constrained optimization. The 'RcppEnsmallen' package includes
-		the header files from the 'Ensmallen' library and pairs the
-		appropriate header files from 'armadillo' through the
-		'RcppArmadillo' package. Therefore, users do not need to
-		install 'Ensmallen' nor 'Armadillo' to use 'RcppEnsmallen'.
-		Note that 'Ensmallen' is licensed under 3-Clause BSD,
-		'Armadillo' starting from 7.800.0 is licensed under Apache
-		License 2, 'RcppArmadillo' (the 'Rcpp' bindings/bridge to
-		'Armadillo') is licensed under the GNU GPL version 2 or later.
-		Thus, 'RcppEnsmallen' is also licensed under similar terms.
-		Note that 'Ensmallen' requires a compiler that supports 'C++11'
-		and 'Armadillo' 8.400 or later.
