Xdelta

Xdelta is a delta generator. That is, given two files it can produce a third file (often shorter), called a delta, which describes the differences between them. It can also apply deltas, that is given the original file and a delta it can produce the second file. The delta algorithm is faster than GNU diff for text files and works well on binary files too.

Xdelta also includes advanced features designed for use by version control systems such as CVS or PRCS. The exact form of these features changed pretty dramatically between Xdelta 0.x and Xdelta 1.x, so consult the Xdelta documentation if this interests you.

Mailing lists and newsgroups

There is a mailing list for xdelta announcements and discussion; to subscribe send a message to majordomo@XCF.Berkeley.EDU whose body is "subscribe xdelta-list".

One newsgroup for Xdelta (and other version control tools) is comp.software.config-mgmt.
