xdelta implemented in java

xdelta implemented in java: "This library implements Josh MacDonalds xdelta binary diff algorithm in java. More information on this algorithm can be found here.

Included is some java code for finding primes copyrighted by Roedy Green. See separate copyright note for that code.

This implementation uses the GDIFF file format for storing binary deltas. There is also a patcher that takes a source file and a patch file in this format and produces the original file.

Some links to other delta / diff implementations (some in java).

* libXDiff implements basic yet complete functionalities to create file diffs for binary and text files.
* jrcs, both an rcs implementation and difference engine in java.
* GNU diff ported to java.
* BDiff, a binary diff tool implemented in C. It uses an LZ77-like algorithm which uses the old file as dictionary.
* XML diff and merge tools, from IBM AlphaWorks
* not a java tool, but the google directory's page on File Comparison."
