xdelta: xdelta (Binary delta generator) xdelta: xdelta: Xdelta is an application program designed to compute changes between xdelta: files. These changes (deltas) are similar to the output of the "diff" xdelta: program in that they may be used to store and transmit only the xdelta: changes between files. However, unlike diff, the output of Xdelta is xdelta: not expressed in a human-readable format. xdelta: Xdelta uses a fast, linear algorithm and performs well on both binary xdelta: and text files. xdelta: xdelta:
