**Purpose**

Takes any dataset that conforms to the fasta format and normalizes it so that all lines of sequence except the last line per named sequence are of the same length.

@description@

  LINE_LENGTH=Integer           The line length to be used for the output fasta file.  Default value: 100.

  TRUNCATE_SEQUENCE_NAMES_AT_WHITESPACE=Boolean
                                Truncate sequence names at first whitespace.  Default value: false. Possible values: {true, false}
