+    (description
+      "This package provides a collection of miscellaneous basic statistic
+functions and convenience wrappers for efficiently describing data.
+The author's intention was to create a toolbox, which facilitates the
+(notoriously time consuming) first descriptive tasks in data analysis,
+consisting of calculating descriptive statistics, drawing graphical
+summaries and reporting the results.  The package contains furthermore
+functions to produce documents using MS Word (or PowerPoint) and functions
+to import data from Excel.  Many of the included functions can be found
+scattered in other packages and other sources written partly by Titans
+of R.  The reason for collecting them here, was primarily to have them
+consolidated in ONE instead of dozens of packages (which themselves might
+depend on other packages which are not needed at all), and to provide a
+common and consistent interface as far as function and arguments naming,
+NA handling, recycling rules etc.  are concerned.  Google style guides
+were used as naming rules (in absence of convincing alternatives).
+The BigCamelCase style was consequently applied to functions borrowed
+from contributed R packages as well.")
