+		'Rcpp' Integration for the 'Armadillo' Templated Linear Algebra
+		Library // 'Armadillo' is a templated C++ linear algebra
+		library (by Conrad Sanderson) that aims towards a good balance
+		between speed and ease of use. Integer, floating point and
+		complex numbers are supported, as well as a subset of
+		trigonometric and statistics functions. Various matrix
+		decompositions are provided through optional integration with
+		LAPACK and ATLAS libraries.  The 'RcppArmadillo' package
+		includes the header files from the templated 'Armadillo'
+		library. Thus users do not need to install 'Armadillo' itself
+		in order to use 'RcppArmadillo'. From release 7.800.0 on,
+		'Armadillo' is licensed under Apache License 2; previous
+		releases were under licensed as MPL 2.0 from version 3.800.0
+		onwards and LGPL-3 prior to that; 'RcppArmadillo' (the 'Rcpp'
+		bindings/bridge to Armadillo) is licensed under the GNU GPL
+		version 2 or later, as is the rest of 'Rcpp'. Armadillo
+		requires a C++11 compiler.
