+     "Kallisto is a program for quantifying abundances of transcripts from
+RNA-Seq data, or more generally of target sequences using high-throughput
+sequencing reads.  It is based on the novel idea of pseudoalignment for
+rapidly determining the compatibility of reads with targets, without the need
+for alignment.  Pseudoalignment of reads preserves the key information needed
+for quantification, and kallisto is therefore not only fast, but also as
+accurate as existing quantification tools.")
