+     "The ACE file format is used in genomics to store contigs from sequencing
+machines.  This tools converts it into FASTQ format.  Both formats contain the
+sequence characters and their corresponding quality information.  Unlike the
+FASTQ file, the ACE file stores the quality values numerically.  The
+conversion algorithm uses the standard Sanger formula.  The package
+facilitates insertion into pipelines, and content inspection.")
