%description
Fast reverse complement of DNA and RNA sequences using a 'C++' lookup
table for O(1) per-base complement mapping. Supports full IUPAC ambiguity
codes, DNA and RNA modes, case preservation, and NA handling. Much faster
than other packages for computing reverse complements of many short
sequences such as primers, probes, and, k-mers.
