+ Xdelta3 is a set of tools designed to compute changes between binary
+ files. These changes (delta files) are similar to the output of the
+ "diff" program, in that they may be used to store and transmit only
+ the changes between files. The "delta files" that Xdelta3 manages are
+ stored in RFC3284 (VCDIFF) format.
