+ "@command{bsdiff} and @command{bspatch} are tools for building and
+applying patches to binary files. By using suffix sorting (specifically
+Larsson and Sadakane's @code{qsufsort}) and taking advantage of how
+executable files change, bsdiff routinely produces binary patches 50-80%
+smaller than those produced by @code{Xdelta}.")
