Yes, but that doesnt help us. To use the method of Xdelta, the user needs to
have the old debian package on his system, which isn't the case normally. We
need the deltas of every individual file, so that we can patch the binaries
directly instead of patching a complete debian package.
How can we make xdelta to compare directories and create deltas for every file
it finds and also add files that are new as deltas?? any suggestions?? or is
there a better suited program for this somewhere?
