usage: fastqAnalyze [-stats] [-o output.fastq] input.fastq
  If no options are given, input.fastq is analyzed and a best guess for the
  QV encoding is output.  Otherwise, the QV encoding is converted to Sanger-style
  using this guess.

  In some cases, the encoding cannot be determined.  When this occurs, no guess is
  output.  For conversion, you can force the input QV type with:

  -solexa     input QV is solexa
  -illumina   input QV is illumina
  -sanger     input QV is sanger

  -o          sanger-style-output.fastq

  If -stats is supplied, no QV analysis or conversion is performed, but some simple
  statistics are computed and output to stdout.
