%description
    bsdiff and bspatch are tools for building and applying patches to
    binary files. By using suffix sorting (specifically, Larsson and
    Sadakane's qsufsort) and taking advantage of how executable files
    change, bsdiff routinely produces binary patches 50-80% smaller than
    those produced by Xdelta, and 15% smaller than those produced by
    .RTPatch (a commercial patch tool).
