+     "Given a set of genomic sites/regions (e.g. ChIP-seq peaks, CpGs,
+differentially methylated CpGs or regions, SNPs, etc.) it is often of interest
+to investigate the intersecting genomic annotations.  Such annotations include
+those relating to gene models (promoters, 5'UTRs, exons, introns, and 3'UTRs),
+CpGs (CpG islands, CpG shores, CpG shelves), or regulatory sequences such as
+enhancers.  The annotatr package provides an easy way to summarize and
+visualize the intersection of genomic sites/regions with genomic
+annotations.")
