+for estimate the significance of overlap among ChIP peak data sets, and
+incorporate GEO database for user to compare the own dataset with those
+deposited in database.  The comparison can be used to infer cooperative
+regulation and thus can be used to generate hypotheses.  Several visualization
+functions are implemented to summarize the coverage of the peak experiment,
+average profile and heatmap of peaks binding to TSS regions, genomic
+annotation, distance to TSS, and overlap of peaks or genes.")
