+     "FastQ Screen is an application which allows you to search a large 
+dataset against a panel of different databases to build up a picture of where
+the sequences in your data originate.  The program was built as a quality
+control check for sequencing pipelines but may also have uses in metagenomics
+studies where mixed samples are expected.  The application generates both text
+and graphical output to inform you what proportion of your library was able to
+map, either uniquely or to more than one location, against each of your
+specified reference genomes.  The user should therefore be able to identify a
+clean sequencing experiment in which the overwhelming majority of reads are
+probably derived from a single genomic origin.")
