**What it does**

Sequence shuffling to obtain new random sequences.

Shuffling options
  --output FILENAME           output to specified FASTA file
  --seed INT                  seed for PRNG, zero to use random data source (0)
  --shuffle FILENAME          shuffle order of sequences pseudo-randomly
  --topn INT                  output just first n sequences
