+random effect models through simple C++ templates.  The package combines
+@code{CppAD} (C++ automatic differentiation), @code{Eigen} (templated
+matrix-vector library) and @code{CHOLMOD} (sparse matrix routines available
+from R) to obtain an efficient implementation of the applied Laplace
+approximation with exact derivatives.  Key features are: Automatic sparseness
+detection, parallelism through BLAS and parallel user templates.")
