+     "This package implements quantile smoothing.  It contains a dataset used
+to produce human chromosomal ideograms for plotting purposes and a collection
+of arrays that contains data of chromosome 14 of 3 colorectal tumors.  The
+package provides functions for painting chromosomal icons, chromosome or
+chromosomal idiogram and other types of plots.  Quantsmooth offers options
+like converting chromosomal ids to their numeric form, retrieving the human
+chromosomal length from NCBI data, retrieving regions of interest in a vector
+of intensities using quantile smoothing, determining cytoband position based
+on the location of the probe, and other useful tools.")
