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.
