+reads to long reference sequences.  It is particularly good at aligning reads
+of about 50 up to 100s or 1,000s of characters, and particularly good at
+aligning to relatively long (e.g. mammalian) genomes.  Bowtie 2 indexes the
+genome with an FM Index to keep its memory footprint small: for the human
+genome, its memory footprint is typically around 3.2 GB.  Bowtie 2 supports
+gapped, local, and paired-end alignment modes.")
