+     "Fastseg implements a very fast and efficient segmentation algorithm.
+It can segment data from DNA microarrays and data from next generation
+sequencing for example to detect copy number segments.  Further it can segment
+data from RNA microarrays like tiling arrays to identify transcripts.  Most
+generally, it can segment data given as a matrix or as a vector.  Various data
+formats can be used as input to fastseg like expression set objects for
+microarrays or GRanges for sequencing data.")
