    <help>
This tool clips adapter sequences from a fastq file and outputs either a
fasta or fastq file of clipped reads with renumbered fasta/fastq headers.

By default clipped sequences with unknown nucleotides are kept, but 
can be discarded by setting "Accept reads containing N?" to reject.

Min size and max size filter clipped reads on their size.

Note that unclipped reads that satisfy the min and max size conditions are kept.
