+Description:  Shreds sequences into shorter, potentially overlapping sequences.
+
+Usage:	shred.sh in=<file> out=<file> length=<number> minlength=<number> overlap=<number>
+
+in=<file>       Input sequences.
+out=<file>      Destination of output shreds.
+length=500      Desired length of shreds.
+minlength=1     Shortest allowed shred.  The last shred of each input sequence may be shorter than desired length.
+overlap=0       Amount of overlap between successive reads.
+reads=-1        If nonnegative, stop after this many input sequences.
+equal=f         Shred each sequence into subsequences of equal size of at most 'length', instead of a fixed size.
+median=0        If nonzero, randomly shred reads to a length with this median.
+variance=0      If median is nonzero, shred to lengths of median +-variance.
+qfake=30        Quality score, if using fastq output.
+
+Please contact Brian Bushnell at bbushnell@lbl.gov if you encounter any problems.
