+       "The porechop package is a tool for finding and removing adapters from 
Oxford
+Nanopore reads.  Adapters on the ends of reads are trimmed off, and when a read
+has an adapter in its middle, it is treated as chimeric and chopped into
+separate reads.  Porechop performs thorough alignments to effectively find
+adapters, even at low sequence identity.  Porechop also supports demultiplexing
+of Nanopore reads that were barcoded with the Native Barcoding Kit, PCR
+Barcoding Kit or Rapid Barcoding Kit.")
