xdelta delta -0 old.cpio new.cpio delta
writedeltarpm new.rpm delta info new.delta.rpm
Finally, remove the temporary working files old.cpio, new.cpio, and delta.
Using applydeltarpm, you can reconstruct the new RPM from the file system if
the old package is already installed:
applydeltarpm new.delta.rpm new.rpm
To derive it from the old RPM without accessing the file system, use the -r option:
applydeltarpm -r old.rpm new.delta.rpm new.rpm
See /usr/share/doc/packages/deltarpm/README" for technical details.
