%description
The LibXDiff library implements basic and yet complete functionalities to 
create file differences/patches to both binary and text files. The library 
uses memory files as file abstraction to achieve both performance and 
portability. For binary files, LibXDiff implements both (with some 
modification) the algorithm described in File System Support for Delta 
Compression by Joshua P. MacDonald, and the algorithm described in 
Fingerprinting By Random Polynomials by Michael O. Rabin. While for text 
files it follows directives described in An O(ND) Difference Algorithm 
and Its Variations by Eugene W. Myers.

This is a merged fork of the forks of the original libxdiff (0.23) found 
in the git and libgit2 source code, converted into a shared library.
