%description
The LibXDiff library implements basic and yet complete functionalities
to create file differences/patches to both binary and text files. It
uses memory files as file abstraction to achieve both performance and
portability. For binary files, it implements (with some modification)
the algorithm described in "File System Support for Delta Compression"
by Joshua P. MacDonald. For text files, it follows directives described
in "An O(ND) Difference Algorithm and Its Variations" by Eugene W.
Myers. Memory files used by the library are basically a collection of
buffers that store the file content.
