  fqlen - Select sequences by size (ver. 0.1)
 -------------------------------------------------------------------------------
  Synopsis:
    fqlen [options] FILE1 FILE2 ... FILEn

  -m, --min INT                   Minimum length to print a sequence
  -x, --max INT                   Maximum length to print a sequence
  -l, --len                       Add read length as comment
  -f, --fasta                     Force FASTA output (default: as INPUT)
  -w, --fasta-width INT           Paginate FASTA sequences (default: no)


  -n, --namescheme                Sequence name scheme:
                - "file" (Use file basename as prefix)
                - "num" (Numbered sequence (see also -p))
                - "raw" (Do not change sequence name (default))
  -p, --prefix STR                Use as sequence name prefix this string
  -c, --strip-comment             Remove sequence comment (default: no)
    
  FILEn                           A FASTA or FASTQ file, gzipped is ok

  Note that usage with multiple files can raise errors (eg. duplicate sequence
  name). Also, wrong formatting if mixing fasta and fastq files without 
  specifying --fasta.
