%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.
