Package deltarpm

Create deltas between rpms

http://gitorious.org/deltarpm/deltarpm

A deltarpm contains the difference between an old
and a new version of a rpm, which makes it possible
to recreate the new rpm from the deltarpm and the old
one. You don't have to have a copy of the old rpm,
deltarpms can also work with installed rpms.
