+    (description
+     "Multivariate data analysis is the simultaneous observation of more than
+one characteristic.  In contrast to the analysis of univariate data, in this
+approach not only a single variable or the relation between two variables can
+be investigated, but the relations between many attributes can be considered.
+For the statistical analysis of chemical data one has to take into account the
+special structure of this type of data.  This package contains about 30
+functions, mostly for regression, classification and model evaluation and
+includes some data sets used in the R help examples.  It was designed as a R
+companion to the book \"Introduction to Multivariate Statistical Analysis in
+Chemometrics\" written by K. Varmuza and P. Filzmoser (2009).")
