+merge paired-end reads from next-generation sequencing experiments.  FLASH is
+designed to merge pairs of reads when the original DNA fragments are shorter
+than twice the length of reads.  The resulting longer reads can significantly
+improve genome assemblies.  They can also improve transcriptome assembly when
+FLASH is used to merge RNA-seq data.")
