+ (description
+ "@dfn{Zero-variance control variates} (ZV-CV) is a post-processing method
+to reduce the variance of Monte Carlo estimators of expectations using the
+derivatives of the log target. Once the derivatives are available, the only
+additional computational effort is in solving a linear regression problem.
+This method has been extended to higher dimensions using regularisation. This
+package can be used to easily perform ZV-CV or regularised ZV-CV when a set of
+samples, derivatives and function evaluations are available. Additional
+functions for applying ZV-CV to two estimators for the normalising constant of
+the posterior distribution in Bayesian statistics are also supplied.")
