<![CDATA[
FLASH (Fast Length Adjustment of SHort reads) is an accurate and fast tool
to merge paired-end reads that were generated from DNA fragments whose
lengths are shorter than twice the length of reads.  Merged read pairs result
in unpaired longer reads, which are generally more desired in genome
assembly and genome analysis processes.

Briefly, the FLASH algorithm considers all possible overlaps at or above a
minimum length between the reads in a pair and chooses the overlap that
results in the lowest mismatch density (proportion of mismatched bases in
the overlapped region).  Ties between multiple overlaps are broken by
considering quality scores at mismatch sites.  When building the merged
sequence, FLASH computes a consensus sequence in the overlapped region.
