+    (description
+      "This package contains a collection of functions to deal with
+nonparametric measurement error problems using deconvolution
+kernel methods.  We focus two measurement error models in the
+package: (1) an additive measurement error model, where the
+goal is to estimate the density or distribution function from
+contaminated data; (2) nonparametric regression model with
+errors-in-variables.  The R functions allow the measurement errors
+to be either homoscedastic or heteroscedastic.  To make the
+deconvolution estimators computationally more efficient in R,
+we adapt the \"Fast Fourier Transform\" (FFT) algorithm for
+density estimation with error-free data to the deconvolution
+kernel estimation.  Several methods for the selection of the
+data-driven smoothing parameter are also provided in the package.
+See details in: Wang, X.F.  and Wang, B. (2011).  Deconvolution
+estimation in measurement error models: The R package decon.
